圆筒形锂电池生产工艺流程英语
圆筒形锂电池生产工艺流程英语Cylindrical Lithium-Ion Battery Production Process.Cylindrical lithium-ion batteries are a common type of battery used in various electronic devices, such as laptops, smartphones, and power tools. The production process of cylindrical lithium-ion batteries involves several key steps:1. Raw Material Preparation.The first step in the production process is the preparation of the raw materials. The main raw materials used in the production of cylindrical lithium-ion batteries are lithium, cobalt, nickel, manganese, and aluminum. These materials are obtained from various sources and are processed to meet the required specifications.2. Cathode and Anode Production.The cathode and anode are the two electrodes of a lithium-ion battery. The cathode is typically made of a lithium-metal oxide compound, such as lithium cobalt oxide (LiCoO2) or lithium nickel manganese cobalt oxide (NMC). The anode is typically made of a carbon-based material, such as graphite or silicon.The cathode and anode materials are synthesized through a series of chemical processes. The cathode material is typically synthesized by mixing lithium salts with metal salts and then heating the mixture at high temperatures. The anode material is typically synthesized by mixing carbon precursors with a binder and then heating the mixture at high temperatures.3. Electrode Coating.Once the cathode and anode materials have been synthesized, they are coated onto metal current collectors. The current collectors are typically made of aluminum or copper. The cathode material is coated onto the positive current collector, and the anode material is coated ontothe negative current collector.The electrode coating process is typically carried out using a slurry method. The cathode or anode material is mixed with a solvent and a binder to form a slurry. The slurry is then coated onto the current collector using a doctor blade or a slot die coater.4. Electrode Drying and Calendering.After the electrodes have been coated, they are dried to remove the solvent. The electrodes are then calendered to improve their density and electrical conductivity. Calendering is a process in which the electrodes are passed through a series of rollers under pressure.5. Cell Assembly.The next step in the production process is the cell assembly. The cell assembly process involves stacking the electrodes together with a separator between them. The separator is a porous material that prevents the electrodesfrom making contact with each other and causing a short circuit.The electrodes and separator are typically stacked together in a winding machine. The winding machine rolls the electrodes and separator into a cylindrical shape.6. Cell Formation.Once the cells have been assembled, they are subjected to a formation process. The formation process involves charging and discharging the cells several times under controlled conditions. The formation process helps to stabilize the electrochemical reactions within the cells and improve their performance.7. Cell Testing.After the cells have been formed, they are tested to ensure that they meet the required specifications. The cells are tested for capacity, voltage, and internal resistance. The cells that do not meet the specificationsare rejected.8. Cell Packaging.The final step in the production process is the cell packaging. The cells are typically packaged in a metal can or a plastic pouch. The packaging protects the cells from the environment and prevents them from being damaged.The cylindrical lithium-ion battery production process is a complex and multi-step process. The quality of the batteries depends on the quality of the raw materials, the precision of the manufacturing processes, and the quality control procedures.。
锂电池生产工艺流程讲解
锂电池生产工艺流程讲解英文回答：Lithium-ion batteries are widely used in various electronic devices, electric vehicles, and renewable energy systems due to their high energy density and long cycle life. The production process of lithium-ion batteries involves several key steps. Let me explain it in detail.1. Electrode Preparation: The first step is to prepare the positive and negative electrodes. The positive electrode is typically made of lithium cobalt oxide (LiCoO2), while the negative electrode is made of graphite. The active materials are mixed with binders, conductive additives, and solvents to form a slurry. The slurry is then coated onto a metal foil and dried to form a thin electrode.2. Electrolyte Preparation: The electrolyte is acrucial component of the lithium-ion battery. It consistsof a lithium salt dissolved in an organic solvent. The most commonly used lithium salt is lithium hexafluorophosphate (LiPF6). The electrolyte is prepared by dissolving the lithium salt in the solvent under controlled conditions.3. Cell Assembly: The next step is to assemble the battery cell. The positive and negative electrodes are stacked together with a separator in between to prevent short circuits. The separator is typically made of a porous polymer material that allows the flow of lithium ions while preventing the direct contact between the electrodes. The electrodes and separator are then rolled or folded into a compact structure.4. Electrolyte Filling: Once the cell is assembled, it is filled with the electrolyte. The electrolyte is injected into the cell through small openings or ports. Care must be taken to ensure that the cell is filled with the correct amount of electrolyte to avoid overfilling or underfilling.5. Sealing: After the electrolyte filling, the cell is sealed to prevent leakage. The sealing process involvesapplying a heat-sealable material or using a laser to weld the cell edges together. This ensures that the cell is hermetically sealed and prevents the escape of electrolyteor the ingress of moisture or contaminants.6. Formation: The final step is the formation process, which involves charging and discharging the battery to activate the electrodes and stabilize the cell performance. During the formation process, the battery undergoes several cycles of charging and discharging at specific voltages and currents. This helps to improve the battery's capacity and overall performance.中文回答：锂离子电池由于其高能量密度和长循环寿命，在各种电子设备、电动车和可再生能源系统中得到广泛应用。

Mixing(配料)Mix solvent and bound separately with positive and negative active materials. Make into positive and negative pasty materials after stirring at high speed till uniformity.Coating（涂布）Now, we are in coating line. We use back reverse coating. This is the slurry-mixing tank. The anode（Cathode）slurry is introduced to the coating header by pneumaticity from the mixing tank. The slurry is coated uniformly on the copper foil, then the solvent is evaporated in this oven. （下面的依据情况而定）There are four temperature zones, they are independently controlled. Zone one sets at 55 degree C, zone two sets at 65 degree C, zone three sets at 80 degree C, zone four sets at 60 degree C. The speed of coating is 4 meters per minute.You see the slurry is dried. The electrode is wound to be a big roll and put into the oven. The time is more than 2 hours and temperature is set at 60 degree C.Throughout the coating, we use micrometer to measure the electrode thickness per about 15 minutes. We do this in order to keep the best consistency of the electrode.Vocabulary:coating line 涂布车间back reverse coating 辊涂coating header 涂布机头Al/copper foil 铝/铜箔degree C 摄氏度temperature zones 温区wind to be a（big）roll 收卷evenly/uniformly 均匀oven 烘箱evaporate 蒸发electrode 极片CuttingCut a roll of positive and negative sheet into smaller sheets according to battery specification and punching request.PressingPress the above positive and negative sheets till they become flat.PunchingPunching sheets into electrodes according to battery specification,ElectrodeAfter coating we compress the electrode with this cylindering machine at about 7meters per minute. Before compress we clean the electrode with vacuum and brush to eliminate any particles. Then the compressed electrode is wound to a big roll. We use micrometer to measure the compressed electrode thickness every 10 minutes. After compressing we cut the web into large pieces. We tape the cathode edge to prevent any possible internal short. The large electrode with edge taped is slit into smaller pieces. This is ultrasonic process that aluminum tabs are welded onto cathodes using ultrasonic weld machine. We tape the weld section to prevent any possible internal short. And finally, we clean the finished electrodes with vacuum and brush.Vocabulary:cylindering 柱形辊压vacuum 真空particle 颗粒wound 旋紧卷绕micrometer 千分尺internal short 内部短路slit 分切ultrasonic 超声波weld 焊接Anode makingIn anode making process, we cut the material into certain length strips. At the mean time, we put a small piece of insulation tape to the tab in order to prevent any possible internal short. Then the prepared nickel tab is riveted on anode and pat plain. We also tape the rivet section to prevent any possible internal short. And finally, we clean the finished electrodes with vacuum and brush.Jelly rollThis is Jelly roll, a manual winding process. In the course of Jelly roll, firstly, we place the separator in between central pins, press the foot switch to turn central pins about 120 degrees. Secondly, place the anode to the edge of central pins, and turn central pins about 180 degrees. Lastly, place the cathode to the edge of central pins. During the winding process, we apply tension by pressing the electrodes and the separator. We put the termination tape at the end.After Jelly roll, we check the short circuit, then form the Jelly roll by pressing, so that it is easier to insert the Jelly roll into the can.Control points:1. When winding to the end of the anode, covering the anode completely by the separator.2. In the whole process, it is the most important points to ensure the best alignment among the cathode, the anode and the separator for the Jelly roll. The separator has to cover the anode and the cathode, and the anode has to cover the cathode completely. These points are mainly checked before short checking.Vocabulary:Jelly roll 卷绕Manual 手工的Separator 隔膜纸central pin 卷针foot switch 脚踏开关anode 负极片cathode 正极片termination tape 尾端胶纸short circuit 短路alignment 整齐Taping & insertingPut the tape on the two side of J/R, To prevent J/R being hurt in the insertion process.Put a piece of tape between cathode tab and J/R .Because anode electrode is wider than cathode electrode.Put the bottom tape.Insert the finished J/R into the can manually and then short circuit check by multi-meter.Spot welding Ni tab to cap.Ultrasonic welding the Al tab to cap using ultrasonic weld.We have the second spot welding to ensure the best contact between the tab and cap.Apply top insulator, to prevent Ni tab contacting with can.Final J/R insertion by the centrifuge.Cap positioning by hand. Then check the cap in the suitable position, or the defects is put into red bin ,Finally , short circuit check again to ensure that there be no internal short J/R flowing to next line.Vocabulary:J/R 极芯tape 胶纸electrode 极片multi-meter 万用表Spot welding 点焊Ni tab 极耳Ultrasonic weld 超焊Insulator 隔圈centrifuge machine 甩壳机defect 次品red bin 红盒Laser weldingThis is the Laser welding room! The first process is welding for the aluminum cap, specially connect the rivet with the weld plate to prevent the cell impedance excursion.The second process is the Laser seam welding. In the process, it must ensure the intensity and airproof characters of the weld.After the cell is welded, we would perform the leak checking, the short circuit checking and the weighing checking.Vocabulary:Laser welding room 激光焊接车间Cap 盖板Rivet 铆钉Plate 镍片impedance excursion 内阻漂移intensity 强度leak checking 检漏short circuit checking 测短路weighing checking 称重Oven drying electrolyte filling and storingThis is the process of cells oven drying at 80℃ for more than 12 hours under vacuum. After oven drying, the cells are transferred to the process of electrolyte filling through this channel. The electrolyte filling performs in dry room. The electrolyte is injected in two times so that it can be filled easily and sufficiently. When filling, vacuum first, then inject electrolyte. After that, we repeat vacuum and vent to room pressure several times. Finally the cell is put off at room pressure, then weigh the cell in order to check the amount of electrolyte. After weighing, we seal with tape onto the filling port to prevent the cells absorbing water during storing.We store the filled cells for 24 hours at room temperature so that the electrolyte can be saturated sufficiently by the anodes and cathodes.Vocabulary:oven drying 烘烤vacuum 真空electrolyte filling 注液electrolyte 电解液room pressure 大气压filling port 注液孔storing 陈化saturated 浸润anode 正极cathode 负极Pre-charge and ball sealAt first, we place a piece of absorb cotton above the filling port to absorb the excess electrolyte. This is the first process.The second process is performing a pre-charge at 0.1C rate for 390 minutes.After the pre-charge, we take a voltage checking to the cell at once. If the voltage is lower than the standard, it needs to be re-charged.The fourth process is the ball seal. we must complete this process in 15 minutes.First, put the steel ball in the right place. Then, give pressure to it so that the steel ball can fill the filling port.In the whole process, we must make sure that the temperature and humidity are in the regular range.Finally, the process is cleaning to eliminate the electrolyte on the cell surface with acetone solvent.Vocabulary:filling port 注液孔electrolyte 电解液pre-charge 预先充电ball seal 封口voltage checking 量电压regular range 合格范围eliminate 消除acetone solvent 丙酮溶剂Aging and FormationThis is the aging room. We age cells at 35~40 Degree C for 7 days. The temperature is controlled by two heating instruments which are set at 38 Degree C. Then we transfer cells to the testing workshop. First, we check the voltage of cells with multi-meters. According to voltage, we divide the cells into acceptables and defects. Formation is done at 1.0 Capacity rate for 140 minutes to 4.2 Voltage. After that, check thickness and impedance. At last, we transfer the acceptables to the storehouse.Vocabulary:aging room 老化房heating instrument 加热器testing workshop 检测车间acceptables 良品defects 次品formation 化成thickness 尺寸，厚度impedance 内阻storehouse 仓库标识牌内容(中文) 英文1 正极球磨Cathode Ball Mill Mixing2 负极球磨Anode Ball Mill Mixing3 正极混浆Cathode Slurry Mixing4 负极混浆Anode Slurry Mixing5 正极涂布Cathode Coating6 负极涂布Anode Coating7 极片烘烤Electrode Drying 8 正极压片Cathode Compress9 负极压片Anode Compress 10 正极分大片Cathode Cutting11 正极分小片Cathode Slitting 12 负极分大片Anode Cutting13 负极分小片Anode Slitting 14 切镍带Anode Tab Cutting15 极耳铆接Anode Riveting 16 极耳贴胶纸Anode Tab Taping17 大片贴胶纸Cathode Edge Taping 18 刷片Electrode Brushing19 极耳超焊#1 Cathode Tab Welding #1装配车间英语极片烘烤Electrode Drying Area裁隔膜纸Separator Cutting壳体贴膜Out-film Apply超焊铝镍带Cathode Tab Welding贴内壁胶纸Inner Insulation Taping卷绕Jelly Roll Winding检验#1 Checking Station#1整形Jelly Roll Forming贴侧面胶纸J/R Side Taping贴上端胶纸J/R Top Taping贴底部胶纸J/R Bottom Taping装壳Jelly Roll Insertion点焊负极Anode Tab Welding剪正极耳Cathode Tab Cutting 超焊正极耳#2 Cathode Tab Welding #2二次点焊Spot Welding套隔圈Insulator Insertion甩壳Final J/R Insertion卡盖板Cap Installation检验#2 Checking Station #2点焊盖板Cap Pre—Welding激光焊接Laser Seam welding 整形Forming检验漏气Leak Checking短路测试Hi—pot称重分档Weighing Sorting。

锂电工艺流程英语
锂电工艺流程英语Lithium-ion batteries, commonly referred to as Li-ion batteries, have revolutionized the energy storage industry, powering our portable electronics, electric vehicles, and even grid-scale energy storage systems. The manufacturing process of these batteries involves several complex steps, each requiring precision and expertise. In this comprehensive guide, we'll explore the English terminology and steps involved in the Lithium-ion battery manufacturing process.**1. Material Preparation**The first step in the Lithium-ion battery manufacturing process is the preparation of raw materials. This involves selecting high-quality cathode and anode active materials, as well as suitable electrolytes and separators. The cathode and anode materials are typically composed of lithium compounds and carbon-based materials, respectively. **2. Electrode Fabrication**Once the raw materials are prepared, the next step is to fabricate the electrodes. This involves mixing theactive materials with binders and conductive additives, and then coating them onto a metal current collector. The most common metal current collectors are aluminum for the cathode and copper for the anode.**3. Electrode Drying and Cutting**After coating, the electrodes undergo a drying process to remove any moisture. Once dry, they are cut into the desired shape and size, ready for the next step in the manufacturing process.**4. Cell Assembly**Cell assembly is a crucial step, where the electrodes, electrolyte, and separator are combined to form the battery cell. The separator, typically made of porous polypropylene or polyethylene, is placed between the cathode and anode to prevent direct contact and thus, short-circuiting. The electrolyte, which is a liquid or solid material, is then added to facilitate the movement of ions between the electrodes.**5. Welding and Sealing**After assembly, the cell is sealed and welded to ensure its structural integrity and prevent leakage of the electrolyte. This step is crucial for ensuring the safety and performance of the battery.**6. Formation and Testing**The formed battery cell is then subjected to a formation process, which involves charging and discharging the cell to activate it. Following formation, the cell is tested to ensure its performance meets specifications. This testing may include capacity testing, internal resistance testing, and cycling tests.**7. Packaging and Final Testing**Once the individual cells are tested and approved, they are packaged into the final battery pack. This packaging may include additional safety features such as thermal cut-off devices and fuses. The final battery pack is then tested again to ensure it meets the required performance and safety standards.**8. Quality Control and Shipping**Quality control is an ongoing process throughout the manufacturing process. However, a final inspection is conducted before the batteries are shipped to customers. This inspection ensures that each battery meets therequired specifications and is safe for use.In conclusion, the Lithium-ion battery manufacturing process is a complex and meticulous procedure, requiring precision and expertise. Understanding the terminology and steps involved in this process is crucial for ensuring the safety, performance, and reliability of the final product. As the demand for Lithium-ion batteries continues to grow, so does the importance of understanding and improving their manufacturing processes.**锂电池生产工艺流程详解**锂电池，特别是锂离子电池（Li-ion），已彻底改变了储能行业，为便携式电子设备、电动汽车甚至电网级储能系统提供了动力。

锂电工艺流程英语
锂电工艺流程英语The lithium-ion battery manufacturing process involves multiple intricate steps that transform raw materials into functional battery components. Here's a brief overview of the lithium-ion battery production process in English:First, raw materials, including lithium compounds, cobalt, nickel, manganese, graphite, and electrolytes, are sourced and carefully inspected to ensure they meet the required quality standards. Next, these materials undergo a meticulous preparation process, where they are mixed in precise ratios to create the cathode, anode, and electrolyte components of the battery. The cathode is typically composed of lithium-based compounds, while the anode is made of graphite or other carbon-based materials. The electrolyte, which facilitates the flow of ions between the cathode and anode, is formulated separately.After the preparation of the battery components, the next step is the assembly process. This involves coating the cathode and anode materials onto metal foils, which are then cut into thin strips called electrodes. These electrodes are stacked or wound together with separators in between to prevent direct contact, creating a cell structure.The assembled cells are then placed into a battery housing, and the electrolyte is injected into the cells. The housing is sealed tightly to prevent any leaks or contamination.Following assembly, the batteries undergo a series of testing procedures to ensure they meet performance and safety standards. This includes checking for proper voltage, capacity, and internal resistance, as well as conducting safety tests to ensure the batteries do not overheat or explode under normal operating conditions. Finally, the batteries are packaged and prepared for shipment to their end-use applications, such as portable electronic devices or electric vehicles.It's worth noting that the lithium-ion battery manufacturing process is highly automated and requires precision equipment to ensure consistent quality and safety. Additionally, the process may vary slightly depending on the specific type of lithium-ion battery being produced, such as lithium-cobalt oxide, lithium-iron phosphate, or lithium-titanate batteries.。

锂电工序英文名称
Cathode slurryThis is the cathode slurry mixing room. First ,we mix the powder with NMP in the mixing tank .And the NMP is added to the mixing tank in three times. Add more NMP to the mixing tank to adjust the slurry viscosity. Finally, transfer the slurry to the coating line after slurry sifting.Anode slurryThis is the anode powder process. First, we mix CMC with water in that anode binder mixing room, and after weighing, the raw material is transferred into the mixing tank. Then, we add the anode binder solution to the mixing tank in 3 times. After that, we add the SBR for the final mixing. and then, we add more water to adjust the slurry viscosity. Next we sift the slurry in that sifting room. Finally, we transfer the finished slurry to the coating line.Vocabulary:viscosity 粘性sifting 筛CoatingNow, we are in coating line. We use back reverse coating. This is the slurry-mixing tank. The anode （Cathode）slurry is introduced to the coating header by pneumaticity from the mixing tank. The slurry is coated uniformly on the copper foil, then the solvent is evaporated in this oven. There are four temperature zones, they are independently controlled. Zone one sets at 55 degree C, zone two sets at 65 degree C, zone three sets at 80 degree C, zone four sets at 60 degree C. The speed of coating is 4 meters per minute.You see the slurry is dried. The electrode is wound to be a big roll and put into the oven. The time is more than 2 hours and temperature is set at 60 degree C.Throughout the coating, we use micrometer to measure the electrode thickness per about 15 minutes. We do this in order to keep the best consistency of the electrode. Vocabulary:coating line 涂布车间back reverse coating 辊涂coating header 涂布机头Al/copper foil 铝/铜箔degree C 摄氏度temperature zones 温区wind to be a（big）roll 收卷evenly/uniformly 均匀oven 烘箱evaporate 蒸发electrode 极片ElectrodeAfter coating we compress the electrode with this cylindering machine at about 7meters per minute. Before compress we clean the electrode with vacuum and brush to eliminate any particles. Then the compressed electrode is wound to a big roll. We use micrometer to measure the compressed electrode thickness every 10 minutes. After compressing we cut the web into large pieces. We tape the cathode edge to prevent any possible internal short. The large electrode with edge taped is slit into smaller pieces. This is ultrasonic process that aluminum tabs are welded onto cathodes using ultrasonic weld machine. We tape the weld section to prevent any possible internal short. And finally, we clean the finished electrodes with vacuum and brush.Vocabulary:cylindering 柱形辊压vacuum 真空particle 颗粒wound 旋紧卷绕micrometer 千分尺internal short 内部短路slit 分切ultrasonic 超声波weld 焊接Anode makingIn anode making process, we cut the nickel roll into certain length strips. At the mean time, we put a small piece of insulation tape to the tab in order to prevent any possible internal short. Then the prepared nickel tab isriveted on anode and pat plain. We also tape the rivet section to prevent any possible internal short. And finally, we clean the finished electrodes with vacuum and brush.Jelly rollThis is Jelly roll, a manual winding process. In the course of Jelly roll, firstly, we place the separator in between central pins, press the foot switch to turn central pins about 120 degrees. Secondly, place the anode to the edge of central pins, and turn central pins about 180 degrees. Lastly, place the cathode to the edge of central pins. During the winding process, we apply tension by pressing the electrodes and the separator. We put the termination tape at the end.After Jelly roll, we check the short circuit, then form the Jelly roll by pressing, so that it is easier to insert the Jelly roll into the can.Control points:1. When winding to the end of the anode, covering the anode completely by the separator.2. In the whole process, it is the most important points to ensure the best alignment among the cathode, the anode and the separator for the Jelly roll. The separator has to cover the anode and the cathode, and the anode has to cover the cathode completely. These points are mainly checked before short checking.Vocabulary:Jelly roll 卷绕Manual 手工的Separator 隔膜纸central pin 卷针foot switch 脚踏开关anode 负极片cathode 正极片termination tape 尾端胶纸short circuit 短路alignment 整齐Taping&insertingPut the tape on the two side of J/R, To prevent J/R being hurt in the insertion process.Put a piece of tape between cathode tab andJ/R .Because anode electrode is wider than cathode electrode.Put the bottom tape.Insert the finished J/R into the can manually and then short circuit check by multi-meter.Spot welding Ni tab to cap.Ultrasonic welding the Al tab to cap using ultrasonic weld.We have the second spot welding to ensure the best contact between the tab and cap.Apply top insulator, to prevent Ni tab contacting with can.Final J/R insertion by the centrifuge.Cap positioning by hand. Then check the cap in the suitable position, or the defects is put into red bin ,Finally , short circuit check again to ensure that there be no internal short J/R flowing to next line.Vocabulary:J/R 极芯tape 胶纸electrode 极片multi-meter 万用表Spot welding 点焊Ni tab 极耳Ultrasonic weld 超焊Insulator 隔圈centrifuge machine 甩壳机defect 次品red bin 红盒Laser weldingThis is the Laser welding room! The first process is welding for the aluminum cap, specially connect the rivet with the weld plate to prevent the cell impedance excursion.The second process is the Laser seam welding. In the process, it must ensure the intensity and airproof characters of the weld.After the cell is welded, we would perform the leak checking, the short circuit checking and the weighing checking.Vocabulary:Laser welding room 激光焊接车间Cap 盖板Rivet 铆钉Plate 镍片impedance excursion 内阻漂移intensity 强度leak checking 检漏short circuit checking 测短路weighing checking 称重Oven drying electrolyte filling and storingThis is the process of cells oven drying at 80℃for more than 12 hours under vacuum. After oven drying, the cells are transferred to the process of electrolyte filling through this channel. The electrolyte filling performs in dry room. The electrolyte is injected in two times so that it can be filled easily and sufficiently. When filling, vacuum first, then inject electrolyte. After that, we repeat vacuum and vent to room pressure several times. Finally the cell is put off at room pressure, then weigh the cell in order to check the amount of electrolyte. After weighing, we seal with tape onto the filling port to prevent the cells absorbing water during storing.We store the filled cells for 24 hours at room temperature so that the electrolyte can be saturated sufficiently by the anodes and cathodes.Vocabulary:oven drying 烘烤vacuum 真空electrolyte filling 注液electrolyte 电解液room pressure 大气压filling port 注液孔storing 陈化saturated 浸润anode 正极cathode 负极Pre-charge and ball sealAt first, we place a piece of absorb cotton above the filling port to absorb the excess electrolyte. This is the first process.The second process is performing a pre-charge at 0.1C rate for 390 minutes.After the pre-charge, we take a voltage checking to the cell at once. If the voltage is lower than the standard, it needs to be re-charged.The fourth process is the ball seal. we must complete this process in 15 minutes.First, put the steel ball in the right place. Then, give pressure to it so that the steel ball can fill the filling port.In the whole process, we must make sure that the temperature and humidity are in the regular range.Finally, the process is cleaning to eliminate the electrolyte on the cell surface with acetone solvent.Vocabulary:filling port 注液孔electrolyte 电解液pre-charge 预先充电voltage checking 量电压ball seal 封口regular range 合格范围eliminate 消除acetone solvent 丙酮溶剂Aging and FormationWelcome! I am the owner! This is the high temperature aging room. Because the temperature is very high, Let’s go out and I will introduce it. We age the cells at 35~40 Degree Celsius for 7 days. The temperature is controlled by two heating units. Then we transfer the cells to the testing workshop.Let me introduce the next process. First, we check the volt of cells with multi-meters over there. In this process we must ensure the multi-meters can normally work. Then we charge the cells at 1 C rate to 4.2.V olt.

锂电池包装车间工艺流程
锂电池包装车间工艺流程英文回答：The process flow of lithium battery packaging in the workshop involves several steps to ensure the safe and efficient packaging of the batteries. Here is a detailed explanation of the process flow:1. Battery Inspection: Before packaging, the batteries need to go through a thorough inspection to check for any defects or damages. This includes checking the voltage, capacity, and overall condition of each battery. Any batteries that fail the inspection will be rejected andsent for further analysis or disposal.2. Battery Sorting: Once the batteries pass the inspection, they are sorted based on their specifications and requirements. This includes sorting them by size, voltage, and capacity. The sorting process helps in organizing the batteries for the subsequent packaging steps.3. Cell Wrapping: The next step is to wrap each individual battery cell with a protective layer. This layer acts as a barrier against moisture, dust, and other external factors that could potentially damage the battery. The wrapping process involves using a heat-sealing machine to securely wrap the battery cells.4. Battery Assembly: After wrapping, the battery cells are assembled into battery packs. This involves connecting the cells together in a series or parallel configuration, depending on the desired voltage and capacity of the final battery pack. The assembly process requires precision and accuracy to ensure the proper functioning of the battery pack.5. Battery Enclosure: Once the battery pack is assembled, it is enclosed in a protective casing. The casing provides additional protection to the battery pack and helps in preventing any external damage. The enclosure process involves placing the battery pack into a pre-designed casing and securing it with screws or clips.6. Labeling and Packaging: The final step in the process is to label and package the battery packs. Each battery pack is labeled with important information such as voltage, capacity, and safety warnings. The packs are then carefully packaged in boxes or cartons, ready for shipment or distribution.中文回答：锂电池包装车间的工艺流程包括多个步骤，以确保电池的安全有效地进行包装。
