Abstract

A non-aqueous electrolyte cell that excels in the high-temperature cycle characteristics and that is without the possibility of solution leakage. The non-aqueous electrolyte cell includes a polymer electrolyte. This polymer electrolyte is a polymerization of a prepolymer included in a prepolymer electrolyte that includes a non-aqueous solvent, an electrolyte salt, and the prepolymer. The prepolymer includes a polyester-based monomer. The polymer electrolyte further includes a vinylene carbonate derivative and cyclic acid anhydride.
