Abstract
Si has a high ability to store Li+ and is expected to be used as the anode material in Li+ secondary batteries of the next generation. However, elemental Si cannot be used for this purpose, as it easily disintegrates due to the volume expansion induced by Li+ storage. This problem may be overcome by combining Si with other materials. The combination of Si with C seems to be quite promising, as both elements belong to the same group in the periodic table of the elements, and C also has a fairly high ability to store Li+. This article introduces two methods to synthesize Si/C composites designed to be used as anode materials for Li+ batteries, and characteristics of the materials obtained through them.
