SAFT Lithium-Ion Polymer Battery Technology 2000-01-3611

SAFT has successfully developed a high energy lithium-ion polymer rechargeable battery delivering 130 Wh/kg and 245 Wh/l as energy densities. The electrolyte, prepared by a phase inversion process, consisted of a porous polymer matrix filled and swollen by a liquid. The electrodes consisted of lithium cobalt oxide (LiCoO2) and graphite as intercalation compounds. Cells were tested for performance including GSM cycling, power, temperature, and charge retention. Also, cells were subjected to safety testing such as nail penetration, crush, over charge and +160C oven storage. This paper focuses on performance and safety data
