First claim
Opening claim text (preview).
The invention claimed is: 1. An electrolyte, comprising: an electrolyte solution that comprises an electrolyte salt and a non-aqueous solvent to dissolve the electrolyte salt, wherein: the non-aqueous solvent is ethylene carbonate, and the electrolyte salt is a lithium salt; and a polymer compound holding the electrolyte solution, wherein the polymer compound includes a copolymer having at least two kinds of repeating units represented by a general formula (1) (In the formula, X represents an oxymethylene group, Y represents a pentafluoroethyl group, R1 represents a methyl group, n and m each represent a molar ratio (n:m) of the two kinds of repeating units, and the n and m satisfy the relationship of 45≤n≤95 and 5≤m≤55). 2. The electrolyte according to claim 1 , wherein the polymer compound further contains a vinylidene fluoride polymer having at least a repeating unit derived from vinylidene fluoride. 3. The electrolyte according to claim 2 , wherein the vinylidene fluoride polymer is at least one of polyvinylidene fluoride and a vinylidene fluoride-hexafluoropropylene copolymer. 4. The electrolyte according to claim 2 , wherein a mass ratio of the copolymer and the vinylidene fluoride polymer is in a range of 20:80 to 50:50.
