The nonaqueous solvent comprises (a) a saturated cyclic carbonate, (b) an unsaturated cyclic carbonate, and (c) a straight chain ester of a saturated aliphatic monocarboxylic acid. The negative electrode contains a fluorine free polymer binder. Rechargeable lithium battery comprises: (A) an electrolyte comprising a lithium salt; dissolved in (B) a nonaqueous solvent comprising: (a) a saturated cyclic carbonate, (b) an unsaturated cyclic carbonate, and (c) a straight chain ester of a saturated aliphatic monocarboxylic acid; (C) at least one positive electrode; and (D) at least one paste type negative electrode comprising: (a) a fluorine free polymer binder, and (b) an electrochemically active carbon material, that is capable of incorporating lithium ions. |
