Abstract

According to embodiments of the present invention, a negative electrode active material for a lithium secondary battery is provided, comprising carbon-based particles and a coating layer bonded to at least a portion of the surface of the carbon-based particles, wherein the coating layer comprises boron and a conductive material. Due to the coating layer, the electrolyte decomposition reaction is suppressed, and the capacity and cycle life of the battery can be improved.
