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.
