Patent ID: 7387852

Claim:
A polymer electrolyte comprising a polymerized product formed by polymerizing a multifunctional isocyanurate monomer of Formula (1) below in a polymer electrolyte forming composition containing the multifunctional isocyanurate monomer, a lithium salt, and a non-aqueous organic solvent: where A 1 , A 2 , and A 3 are independently C 1 -C 10 alkylene groups or C 1 -C 10 arylene groups; and Z 1 , Z 2 , and Z 3 are substitute groups of Formula (2) below: where X is each of R 1 and R 2 is at least one independently selected from the group consisting of hydrogen, C 1 -C 10 alkyl, C 1 -C 10 fluorinated alkyl, C 1 -C 10 aryl, and C 1 -C 10 fluorinated aryl; m is an integer from 0 to 10; and n is an integer from 0 to 5 and wherein the non-aqueous organic solvent is selected from the group consisting of ethylene carbonate, propylene carbonate, dimethyl carbonate, methylethyl carbonate, diethyl carbonate, methylpropyl carbonate, ethylpropyl carbonate, methylbutyl carbonate, tetrahydrofuran, 2-methyltetrahydrofuran, diethoxyethane, methylformate, ethylformate, triglyme, tetraglyme, fluorobenzene, difluorobenzene, γ-butyrolactone, and mixtures of at least two of the foregoing solvents, and the amount of the organic solvent is in the range of 10-5000 parts by weight with respect to 100 parts by weight of the monomer.
