Patent ID: 7410729

Claim:
A non-aqueous electrolyte cell comprising: a positive electrode; a negative electrode; and a polymer electrolyte, wherein: the polymer electrolyte is formed from a prepolymer electrolyte having a prepolymer wherein the prepolymer is polymerized, the prepolymer electrolyte further comprising a non-aqueous solvent and an electrolyte salt; the prepolymer includes a polyester-based monomer; and the prepolymer electrolyte further includes a vinylene carbonate derivative and cyclic acid anhydride, said cyclic acid anhydride is a component separate from the polyester-based monomer; wherein the polyester-based monomer is at least one selected from the group consisting of the following formulas 1,2,3,3′,3″ and 4; CH2═CR—CO—(O—A1-CO) m -O—R1 Formula 1 R:H, R1:CH 3 ,A1:C 5 H 10 , m =6; CH 2 ═CR2—CO—(O-A2-CO) m 1-CH 2 —CH 2 —(O-A2-CO) m 1-CO—CR2═CH 2 Formula 2 R2:H,A2:C 5 H 10 ,m 1=4;
