Document Type and Number:
Japanese Patent JP2699280
Kind Code:
B2
Abstract:
A solid polymeric electrolyte is constituted by a solid solution of an ionic compound in a cross-linked polyether, wherein this latter is the copolymerization product of a vinyl-ether of formula: R-(O-CH2-CH2)n-O-CH=CH2 (I) wherein: R is the methyl or ethyl radical; and n is an integer comprised within the range of from 1 to 16; with a di-vinyl-ether of formula: CH2=CH-(O-CH2-CH2)m-O-CH=CH2 (II) wherein: m is an integer comprised within the range of from 1 to 16; with a molar ratio of the di-vinyl-ether (II) to the vinyl-ether (I) comprised within the range of from 1/100 to 10/100; with said polyether having a weight average molecular weight of about 10,000, and a glass transition temperature (Tg) comprised within the range of from -60 DEG C to -80 DEG C. Such a a solid polymeric electrolyte is used in the manufacturing of high-energy-density electrochemical generators.
