Title:
METHOD FOR PRODUCING CARBON-COATED SILICON MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/031126
Kind Code:
A1
Abstract:
Provided are: a silicon material which is more preferable than conventional silicon materials; and a method for producing the silicon material.
A method for producing a carbon-coated silicon material, which is characterized by comprising:
a layered silicon compound production step wherein a layered silicon compound is obtained by having CaSi2 react with an acid;
a silicon material production step wherein a silicon material is obtained by heating the layered silicon compound at a temperature of 300°C or more;
a coating step wherein the silicon material is coated with carbon; and
a cleaning step wherein the silicon material before or after the coating step is cleaned with use of a solvent having a relative dielectric constant of 5 or more.
