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:
The present invention relates to a negative active material for a lithium secondary battery which includes a metal oxide-based core material and a carbon material disposed on the surface of the core material, a method of preparing the same, and a lithium secondary battery including the negative active material. According to the present invention, a negative active material for a lithium secondary battery is prepared by coating a core material having good energy density per unit volume with a carbon material, thereby improving the cycle life and charge-discharge characteristics of a lithium secondary battery at a high rate.
摘要:
The present invention relates to an active material for a rechargeable lithium battery and a rechargeable lithium battery including the same. The active material includes an active material and a fiber-shaped or tube-shaped carbon conductive material attached to the surface of the active material. The active material includes a conductive shell including a fiber-shaped or tube-shaped carbon conductive material and increases discharge capacity due to improved conductivity and improves cycle-life efficiency by maintaining paths between active material particles during charge and discharge cycles.
