LITHIUM ION SECONDARY BATTERY AND CHARGE/DISCHARGE CONTROLLING SYSTEM THEREOF |
摘要 |
A lithium ion secondary battery includes a positive electrode containing a composite lithium oxide, a negative electrode capable of absorbing and desorbing lithium ions, a sheet-like separator interposed between the positive electrode and the negative electrode, a non-aqueous electrolyte and a porous electron-insulating film attached to the surface of the negative electrode. The sheet-like separator is a monolayer film made of polypropylene resin or a multilayer film whose layer to be in contact with the positive electrode is made of polypropylene resin. The porous electron-insulating film includes an inorganic oxide filler and a binder. The sheet-like separator has a thickness not less than 1.5 times the thickness of the porous electron-insulating film. |
