| description | A method for preparing three-dimensional porous silicon by taking silicate glass as a raw material, comprising the following steps: mechanically milling silicate glass into powder; uniformly mixing the powder with magnesium powder and fused salt according to a certain ratio to undergo a reaction in an environment of inert gas; and acid-cleaning the reaction product to obtain three-dimensional porous silicon. Steps of the method are simple and easy to operate, include a wide range of raw materials, and facilitate formation of the three-dimensional porous silicon with a stable structure after reaction in a molten state. The prepared three-dimensional porous silicon has high purity, a large specific surface area, a uniform size of particles, has a mesoporous, and can be applied in the field of negative electrode materials of lithium ion batteries.
