NEGATIVE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, METHOD OF PREPARING SAME, AND LITHIUM SECONDARY BATTERY COMPRISING SAME |
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. |
