Separator, gel electrolyte, non-aqueous electrolyte and battery using them

An inorganic compound with a specific inductive capacity not less than 12 is contained in a gelated electrolyte. This improves the degree of dissociation of a lithium compound as an electrolytic salt contained in the gelated electrolyte, the dielectric constant of the gelated electrolyte and ion conductivity, while preventing crystallization under a low temperature environment.

This improves the degree of dissociation of the lithium compound as an electrolytic salt and the degree of dissociation of the lithium compound as an electrolytic salt, while preventing crystallization under a low temperature environment.
