COMPOSITE CARBON MATERIAL FOR NONAQUEOUS SECONDARY BATTERY AND METHOD FOR MANUFACTURING THE SAME, NEGATIVE ELECTRODE, AND NONAQUEOUS SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a negative electrode material for a nonaqueous secondary battery, high in capacity and good in cycle characteristics.

SOLUTION: A composite carbon material for a nonaqueous electrolyte secondary battery is produced to provide a negative electrode material for a nonaqueous secondary battery. The composite carbon material for a nonaqueous electrolyte secondary battery contains a metal particle and a graphitic material, and the metal particle has a minimum particle size of 50 nm or more and a maximum particle size of 16 μm or less.
