高分子電解質リチウム二次電池
Document Type and Number:
Japanese Patent JP4004158
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a high polymer electrolyte lithium secondary battery having a large discharge capacity and good charge-discharge cyclic characteristics. SOLUTION: A lithium secondary battery includes a high polymer electrolyte formed by impregnating homopolymer having a weight mean molecular weight 2×103-5×105 as a polymeride of monomers expressed by a formula with non- aqueous electrolytic solution. In the formula, R1-R3 are H or 1-4C alkyl group, being identical or different, provided that at least two of them are H and at least one of H in R1-R3 is substituted with F, and R4 and R5 are 1-4C alkylene group, being identical or different, and R6-R8 are H or 1-4C alkyl group, being identical or different, provided that at least two of them are H and at least one of H in R6-R8 is substituted with F.
