    摘要: A polymer electrolyte capable of obtaining superior discharge characteristics and a battery using it are provided. A cathode (21) and an anode (22) are wound with a separator (24) in between. After that, the wound body is contained inside a package member. Then, an electrolytic composition containing a solvent, polyvinyl acetal or the derivative thereof, and lithium hexafluorophosphate is added thereto. Polyvinyl acetal or the derivative thereof is polymerized by using lithium hexafluorophosphate as a catalyst. Thereby, a polymer electrolyte (23) is formed, and the discharge characteristics are improved.

    摘要: A battery is provided which has a high capacity and can improve battery characteristics, such as cycle characteristics. The battery includes a spirally wound electrode body, wherein a cathode and an anode are wound with a separator in between. The anode includes, for example, simple substances, alloys, compounds of metal elements or metalloid elements capable of forming an alloy with Li, the like and combinations thereof. An electrolytic solution wherein an electrolyte salt is dissolved in a solvent is impregnated in the separator. For the electrolyte salt, a light metallic salt having B—O bond or P—O bond, such as difluoro[oxalato-O,O′]lithium borate and tetra fluoro[oxalato-O,O′]lithium phosphate, can be used. By forming a stable coating, decomposition reaction of the solvent can be inhibited, and reaction between the anode and the solvent can be prevented.
