Abstract

A negative electrode for a lithium secondary battery of the present invention includes a negative active material including a plate-shaped carbon powder particle agglomerated in a primary structure in which the plate-shaped particle is oriented in a plane direction and laminated. Fine carbon powder particles are then agglomerated to form a secondary structure on the surface of the primary structure such that the resulting particles include fine pores formed on the surface.
