SILICON COMPOSITE, MAKING METHOD, AND NON-AQUEOUS ELECTROLYTE SECONDARY CELL NEGATIVE ELECTRODE MATERIAL |
摘要 |
A silicon composite comprises silicon particles whose surface is at least partially coated with a silicon carbide layer. It is prepared by subjecting a silicon powder to thermal CVD with an organic hydrocarbon gas and/or vapor at 900-1,400° C., and heating the powder for removing an excess free carbon layer from the surface through oxidative decomposition. |
