Document Type and Number:
WIPO Patent Application WO/2017/154449
Kind Code:
A1
Abstract:
A gel electrolyte is provided which has a low matrix polymer concentration and which can maintain a gel state. This gel polymer contains a matrix polymer, and a nonaqueous electrolytic solution comprising a lithium-containing electrolyte dissolved in a non-aqueous solvent, wherein the matrix polymer is a copolymer including vinylidene fluoride units and fluorine atom-containing monomer units, and, for the concentration C (mass%) of the matrix polymer in the gel electrolyte, the melting temperature Tm of the matrix polymer satisfies the equation Tm ≧ 145 - C (I) (In expression (I), 0.1 ≦ C ≦ 30).
