Gurley 数 ：一定体积的气体，在一定压力条件下通过 一定面积的隔膜所需要的时间。与隔膜装配的电池的内阻 成正比，即该数值越大，则内阻越大。
单纯比较两种不同隔膜的 Gurley 数是没有意义的，因 为可能两种隔膜的微观结构完全不一样；但同一种隔膜的 Gurley 数的大小能很好的反应出内阻的大小，因为同一 种隔膜相对来说微观结构是一样的或可比较的。
采用该法的具有代表性的公司有日本旭化成、东燃及美 国Entek等，目前主要用于单层的PE隔膜。
湿法 PE 的微孔结构 （20,000倍）
虽然孔隙率和透气性 可控范围大，但由于 湿法工艺需要消耗大 量的有机溶剂，一方 面要考虑溶剂的回收 利用，工艺复杂度增 加，使成本增加，另 一方面，污染环境。
从干、湿两种方法上看，干法双向拉伸工艺生 产的隔膜在物理性能、机械性能方面更占优势， 能够满足动力电池大电流充放电的要求。所以， 干法双向拉伸工艺生产的隔膜更适合应用于电 动汽车用动力电池。
干法双拉 PE 的微孔结构 （20,000倍）

湿法
湿法又称相分离法或热致相分离法，将高沸点小分子作 为致孔剂添加到聚烯烃中，加热熔融成均匀体系，然后降 温发生相分离，拉伸后用有机溶剂萃取出小分子，可制备 出相互贯通的微孔膜材料。
目前所使用的电极颗粒一般在 10 微米的量级，而所使 用的导电添加剂则在 10 纳米的量级，不过很幸运的是 一般碳黑颗粒倾向于团聚形成大颗粒。一般来说，亚微 米孔径的隔膜足以阻止电极颗粒的直接通过，当然也不 排除有些电极表面处理不好，粉尘较多导致的一些诸如 微短路等情况。

液态电解液锂离子电池隔膜综述
液态电解液锂离⼦电池隔膜综述⼀、隔膜种类⽬前根据隔膜材料构成可分为三种，三种材质及其各⾃主要特点，具体如下图所⽰。
⼆、隔膜要求及表征。
隔膜的基本功能是阻电⼦通离⼦，就是为正负极提供物理连接，允许⾃由离⼦（锂离⼦）流动，阻隔电⼦的流动。
考虑到电池的能量、功率密度、循环寿命和安全等特性，对隔膜的要求如下：1）化学稳定性。
要求不与电解液及电极材料反映。
2）厚度。
原则上是越薄越好，但是考虑其均⼀性、稳定性和安全性，需要选取合适的厚度。
隔膜厚度⼀般在20微⽶左右。
3）孔隙率。
合适的孔隙率有助于保留⾜够的电解液，以提供⾃由离⼦的传输，但是过⾼的孔隙率不利于材料⾼温热关断，在融化或软化时更容易收缩，引起安全问题。
⼀般锂离⼦电池隔膜的孔隙率在40%左右。
4）孔径。
孔径必须⼩于电极材料离⼦尺⼨，包括电极活性材料、导电添加剂等。
现实情况下，考虑空隙的曲折机构有助于阻⽌粒⼦到达相反电极侧，亚微⽶孔径的薄膜能够阻⽌正负极粒⼦的相互渗透。
5）渗透性。
隔膜不应该限制电池的电性能。
通常隔膜的存在会增加电解液的有效电阻4~5倍。
均匀渗透性的隔膜对于电池的长循环寿命很重要。
渗透性不均匀会导致不均匀⼀的电流密度分布，这被证实为锂离⼦电池负极锂枝晶形成的主要原因。
6）机械强度。
隔膜的机械强度可通过纵向拉伸⽅向和横向拉伸⽅向的拉伸强度、撕裂强度和穿刺强度表征。
7）浸润性。
隔膜在电解液中需要很快的浸润，并长久保持电解液。
前者有利于电池的组装，后者有利于电池的寿命。
8）尺⼨稳定性。
电池在电解液内要保持平坦，不能发⽣弯曲或倾斜。
9）热收缩。
考虑到聚烯烃材料的晶体和⾮晶象的密度不同，即使隔膜很低孔隙率，在温度达到软化温度后，就会发⽣收缩。
10）关闭。
锂离⼦电池隔膜在低于热失控温度时有电池关闭的能⼒，且关闭后不会造成机械完整性的损失。
对于锂离⼦电池使⽤的PE-PP双层隔膜，具有130℃的关闭温度，165摄⽒度的融化温度。
三、隔膜类型及制造考虑到隔膜结构和组成，隔膜类型分为：微孔聚合物隔膜、⽆纺布隔膜和⽆机复合隔膜。
