Abstract:
Negative active material compositions for rechargeable lithium batteries, negative electrodes for rechargeable lithium batteries, and rechargeable lithium batteries using the negative active material compositions are provided. The negative active material composition includes a negative active material, a polyimide precursor compound, and a highly flexible polymer. The negative active material composition prevents the electrode substrate from bending, thereby improving the capacity and cycle-life characteristics of the battery.
