Title:
FLAME-RETARDANT SOLID ELECTROLYTE
Document Type and Number:
Japanese Patent JP3729610
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a solid electrolyte that restrains ignition due to short- circuit in a battery by employing an electrolyte consisting of an ion conductive polymer containing a frame-retardant group for skeleton or nonion conductive polymer, an electrolytic salt, and an organic solvent.
SOLUTION: A flame-retardant group is introduced by at least one kind of compound to be selected from formulas I and II. In formula I, R1 denotes aliphatic hydrocarbon containing halogen or aromatic hydrocarbon containing halogen, R'OR1; R2 denotes H, CH3; n denotes 1 to 3. In formula II, R2 denotes H, CH3; R3 denotes aliphatic or aromatic hydrocarbon; R4 denotes H, aliphatic or aromatic hydrocarbon; m denotes 1 to 3, and n denotes 1 to 20. In formula III, R2 denotes H, CH3; R3 denotes aliphatic or aromatic hydrocarbon, (R3O)m-R5; n denotes 1 to 20. Skeleton of ion conductivity polymer is preferably deformed alkylene oxide and/or glycidyl ether or the like, and skeleton of non-ion conductivity polymer is vinylidene fluoride acrylonitrile, or methyl methacrylate.
