Negative active material for lithium secondary battery and negative electrode and lithium secondary battery comprising same
摘要：
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.
摘要（中）：

本发明的锂二次电池用负极包括负极活性物质，该负极活性物质包括在板状颗粒沿平面方向取向并层叠的一次结构中凝聚的板状碳粉末颗粒。 然后将细碳粉末颗粒附聚在一次结构的表面上形成二级结构，使得所得到的颗粒包括在表面上形成的细孔。
