A rechargeable lithium battery includes a negative electrode including a negative active material, a positive electrode including a positive active material, an electrolyte including a polymer, an additive having a borate structure, a lithium salt, and an organic solvent. The electrolyte includes about 0.1 wt % to about 10 wt % of the additive having a borate structure based on 100 wt % of the electrolyte. The organic solvent includes an acetate-based compound and a cyclic carbonate-based compound, and an amount of the acetate-based compound is larger than that of the cyclic carbonate-based compound. |
