Abstract
A lithium secondary battery includes a positive electrode having a positive electrode active material, a negative electrode having a negative electrode active material, a separator separating the positive electrode from the negative electrode, and an electrolyte. The negative electrode active material includes a graphite core particle, at least one metal particle located on the graphite core particle, and a polymer film coating the graphite core particle and the at least one metal particle. The polymer includes a polyimide- or polyacrylate-based polymer.
