SILICON COMPOSITE AND METHOD OF MANUFACTURING THE SAME, AND NEGATIVE ELECTRODE MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a silicon composite which is used as a negative electrode material for a non-aqueous electrode secondary battery, has excellent cycle characteristic, is manufactured by a simple method and sufficiently tolerates the industrial scale production.

SOLUTION: The silicon composite is a particle having structure formed by dispersing fine crystals of silicon in a silicon based compound except a particle having the surface coated with carbon.
