MANUFACTURING METHOD OF NEGATIVE ELECTRODE ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NEGATIVE ELECTRODE ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTE BATTERY PROVIDED THEREBY

摘要

PROBLEM TO BE SOLVED: To provide a negative electrode active material for a nonaqueous electrolyte secondary battery which has high capacity, and to provide a high capacity battery using it.

SOLUTION: A high-capacity battery uses a negative electrode active material for a nonaqueous electrolyte secondary battery that is a compound containing three phases of a minute Si phase, SiO2, and a carbonaceous substance. The negative electrode active material can be manufactured by burning SiOx and carbonaceous substance material.
