PURPOSE:To provide a lithium ion conductive polymer electrolyte with a good lithium ion conductive property and prevent the electrolyte from reacting with lithium, by using polyvinyl alkyl ether as an organic polymer for making a complex substance with a lithium salt. CONSTITUTION:A lithium ion conductive polymer electrolyte is made of a complex substance of a lithium salt and an organic polymer which is polyvinyl alkyl ether whose alkyl group has three or more carbon atoms and is preferably a methyl group or an ethyl group. The number average molecular weight of the polymer is not less than 5,000 and is usually 10,000-200,000. The polymer is solid or semisolid at the room temperature. |
