14.2 g of stearic acid was added to 200 ml of an ethanol solution and sufficiently stirred at 60° C. until the stearic acid was completely dissolved. 5.0 g of copper acetate-monohydrate was dissolved in 200 ml of ethanol solution. Then, the two solutions were mixed and stirred for 3 hours. White powder on the surface of the result was collected and washed three times each with distilled water and with methanol to obtain copper stearate. An anode active material was prepared as in Example 1, except that copper stearate was used, the molar ratio of copper to silicon was 0.2:1, the weight ratio of silicon to graphite was 0.5:1, and the carbon layer was 6.3 wt % of the anode active material.
