Title:
HIGH POLYMER GEL ELECTROLYTE AND SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP3460941
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a high polymer gel electrolyte that can realize high ion conductivity and excellent dynamic characteristics with good balance, is excellent in electrolytic solution retention at high temperatures and is easy to manufacture.
SOLUTION: This high polymer gel electrolyte comprises a matrix polymer and an electrolytic solution that is contained in it and is made by dissolving an ionic compound in a nonaqueous organic solvent; the matrix polymer is made by forming a high polymer network by diffusing a compound containing not less than two polymer functional groups in the same molecule and another compound having a polymer functional group and containing an amide group into vinylidene fluoride copolymer and polymerizing them together.
