摘要：
A metallic silicon-containing composite in which metallic silicon nuclei are coated with an inert material which does not contribute to adsorption and desorption of lithium ions is a useful negative electrode material for lithium ion secondary batteries. Using the composite as a negative electrode active material, a lithium ion secondary battery having a high capacity and excellent cycle performance can be fabricated.
