Title:
POLYMER SOLID ELECTROLYTE AND NONAQUEOUS BATTERY USING SAME
Document Type and Number:
Japanese Patent JP3948805
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a high-polymer solid electrolyte having sufficient ion- conductivity and excelling in a shape-holding property and mechanical strength, and a nonaqueous battery using this and excelling in a discharge-capacity maintaining rate.
SOLUTION: In a cross-linked copolymer obtained by cross-linking a copolymeric composition into which 100 pts.wt. of a copolymer, composed of 50 to 70 wt.% of a repeated unit derived from aliphatic conjugate diene and 30 to 95 wt.% of a repeated unit derived from a polar compound shown by formula (1), is compounded with 0.1 to 10 pts.wt. of an organic peroxide, cross- linkage density of the cross-linked copolymer is 1.0×10-5 mol/cc or more, a value of modulus of tensile modulus of elasticity conforming to JIS K7127 is 0.1 kgf/cm2 or more, and a γ-butyrolactone or an ethylene carbonate and a chain carbonate are used as main constituents of a nonaqueous solvent.
