  • Polymer electrolytes and lithium secondary battery containing the same
    Patent number: 6833219
    Abstract: A polymer electrolyte for use in a lithium secondary battery prepared by polymerizing a composition including 0.1 to 90% by weight of a first compound represented by formula 1, a second compound represented by formula 2 or a mixture thereof, 0.1 to 90% by weight of a third compound represented by formula 3, and 9.8 to 99.8% by weight of a nonaqueous organic solvent containing 0.5 to 2.0 M of a lithium salt. Formula 1 is CH(R1)═C(R2)—C(═O)O—R3-N(R4)(R5), Formula 2 is CH(R1)═C(R2)—C(═O)O—R3-CN, and Formula 3 is Z—{—Y—X—C(R2)═CH(R1)}n.
