Patent ID: 8802285

Claim:
A lithium battery, comprising: a cathode; an anode; and an organic electrolytic solution, wherein a film is present on a surface of the anode or cathode, the film being a polymerization product of a cycloolefin monomer, wherein the polymerization product of the cycloolefin monomer is a compound represented by Formula 13: wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , and R 10 in Formula 13 are each independently a hydrogen atom, a halogen atom, a hydroxyl group, a carboxyl group, an amino group, a cyano group, a substituted or unsubstituted C 1-20 alkyl group, a substituted or unsubstituted C 1-20 alkoxy group, a substituted or unsubstituted C 2-20 alkenyl group, a substituted or unsubstituted C 2-20 alkynyl group, a substituted or unsubstituted C 6-30 aryl group, a substituted or unsubstituted C 7-30 arylalkyl group, a substituted or unsubstituted C 7-30 alkylaryl group, a substituted or unsubstituted C 1-20 heteroalkyl group, a substituted or unsubstituted C 4-30 heteroaryl group, a C 7-30 arylcarbonyl group, a C 2-20 alkyloxycarbonyl group, a C 2-20 alkylcarbonyl group, or a C 2-20 alkylcarbonyloxy group, wherein R 4 and R 5 together may also represent ═O, R 7 and R 9 may also be bound to each other to form a five-membered ring or six-membered ring structure, or a hetero cyclic structure, and R 8 and R 10 together may also represent single bond, and n is an integer of 1 to 100,000.
