Hsu3 3C STOBA (Self-Terminated Oligomers with hyper-Branched Architecture) 20 09 (R&D 100 Awards) Lithium-ion batteries are provided with the properties of high energy densities, high power densities and long cycle life. Therefore, Lithium-i on batteries are provided with the most development value in the 3C electr onic industry field and Electrical Vehicle market. One of the key technolo gies is high power lithium batteries material and the other is the safety issue of lithium-ion batteries. Industrial Technology Research Institute h as developed the nano-polymer material STOBA (Self-Terminated Oligomers wi th hyper-Branched Architecture) that can enhance the safety issue of lithi um-ion batteries. On the other hand, this material can preserve the basic capacity and high temperature cycle life. Therefore, this novel technology of STOBA in lithium-ion battery obtains the R&D 100 Awards for 2009. /Key Words (High Safety Lithium-ion Batteries) with hyper-Branched Ar chitecture) STOBA (Self-Terminated Oligomers (Thermal Runaway) 3C 2006 (DELL) 410 SONY 077 275 2009/11 2006/8 2006/12 2007/3 2007/3 2007/6 2007/7 2007/8 2008/3 SONY SANYO SANYO SANYO NEC SONY PANASONIC NEC Note-PC Note-PC DELL LENOVO KDDI AU 355 20 2 — >100 — Note-PC TOSHIBA NOKIA AU (NOKIA) IBM 2009 iPhone (APPLE) 3C (Thermal Runaway) 1990 Sony Energetic Inc.
