ANODE ACTIVE MATERIAL COMPOSITION FOR LITHIUM BATTERY AND PREPARATION THEREOF

摘要

PURPOSE: An anode active material composition for a lithium battery is provided to increase charge/discharge efficiency of a battery and to prevent the deterioration of an anode active material by forming a stable passive layer on the anode active material. CONSTITUTION: The anode active material composition for a lithium battery comprises: an anode active material; a compound represented by the formula of (CF)x, in which x ranges from 0.8 to 1; a binder; and a solvent, wherein the amount of (CF)x is 1.5 wt% based on the weight of the anode active material. Particularly, the anode active material is selected from the group consisting of hard carbon and soft carbon, the binder is selected from the group consisting of PVDF and PTFE and the solvent is NMP.
