A rechargeable lithium battery includes a positive electrode including a positive active material being capable of intercalating or deintercalating lithium; a negative electrode including a carbon-based negative active material and a water-soluble binder; and a polymer electrolyte including a polymer, a non-aqueous organic solvent and a lithium salt, wherein the polymer comprises a polymerization product of a first monomer represented by Chemical Formula 1 with a second monomer which is one or more of monomers represented by Chemical Formulae 2 to 7:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Chemical Formula 1 €ƒ€ƒ€ƒ€ƒ€ƒA-U-B In Chemical Formula 1, A and B are the same or different, and are one of CH 2 =CR-C(=O)-, CH 2 =CR-O-CH 2 -, CH 2 =CR-, CH 2 =CR-O-C(=O)-, CH 2 =CR-CH 2 -, CH 2 =CR-CH 2 -O-, CH 2 =CH-S(=O) 2 -, or CH 2 =CR-C(=O)-O-CH 2 CH 2 -NH-C(=O)-, where R is H, a C 1 to C 10 hydrocarbon, or a C 6 to C 10 aromatic hydrocarbon.
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Chemical Formula 2 €ƒ€ƒ€ƒ€ƒ€ƒCH 2 =CL1-C(=O)-O-M
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Chemical Formula 3 €ƒ€ƒ€ƒ€ƒ€ƒCH 2 =CL1-O-M
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Chemical Formula 4 €ƒ€ƒ€ƒ€ƒ€ƒCH 2 =CL1-O-C(=O)-M
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Chemical Formula 5 €ƒ€ƒ€ƒ€ƒ€ƒCH 2 =CH-CH 2 -O-M
