Abstract

A mesoporous silicon compound includes a mesoporous silicon phase, a metal silicide phase, and a carbon phase. The metal silicide is embedded in mesoporous silicon particles, the surfaces of which are coated with a carbon layer. A weight ratio of elemental silicon to the metal element is from 2:3 to 900:1. The pores of the mesoporous silicon particles have a size distribution from two nanometers to eighty nanometers.
