Abstract:
A cathode active material composition includes a cathode active material, a water-based binder, and a transition metal oxide. A cathode is prepared using the cathode active material composition. A lithium battery includes the cathode. The lithium battery has improved high-rate characteristics and lifespan characteristics by preventing an increase in internal resistance due to the corrosion of an electrode base material.
