Abstract
A production process for carbon-coated silicon material includes the step of: heating CaSi2 and a halogen-containing polymer at a temperature being a carbonization temperature or more of the halogen-containing polymer in a state where the CaSi2 and the halogen-containing polymer coexist.

A production process for carbon-coated silicon material, the production process comprising the step of:
- letting CaSi2 and a halogen-containing polymer coexist under a noncontact condition and then heating the CaSi2 and the halogen-containing polymer at a temperature being a carbonization temperature or more of the halogen-containing polymer while the CaSi2 and the halogen-containing polymer coexist under the noncontact condition to obtain a carbon-coated silicon material.
A production process for carbon-coated silicon material, the production process comprising the step of:
- heating CaSi2 and a halogen-containing polymer at a temperature being a carbonization temperature or more of the halogen-containing polymer in a state where the CaSi2 and the halogen-containing polymer coexist to obtain a carbon-coated silicon material, and
- further comprising an additional carbon coating step of further coating carbon onto the carbon-coated silicon material.
