| 摘要 |
The invention relates to a polymer electrolyte for a lithium secondary battery. The polymer electrolyte comprises:
a non-aqueous organic solvent;
a lithium salt; and
a polymer being obtained by polymerization of at least one monomer represented by Formula 1: A - polyesterpolyol - B
wherein the polyesterpolyol is being obtained by condensation of at least one alcohol having from 2 to 6 OH groups and at least one dicarboxylic acid, the polyesterpolyol having a weight average molecular weight ranging from about 100 to about 10,000,000, and each of A and B are linked to terminal OH groups of the polyesterpolyol, each of A and B being selected from the group consisting of CH 2 =CR-C(=O)-, CH 2 =CR-O-CH 2 -, CH 2 =CR-, CH 2 =CR-O-C(=O)-, CH 2 =CH-CH 2 -O-, CH 2 =CH-S(=O) 2 -, and CH 2 =CR-C(=O)-O-CH 2 CH 2 -NH-C(=O)-, wherein R is selected from the group consisting of C 1 to C 10 hydrocarbons and C 6 to C 10 aromatic hydrocarbons. |
