摘要

To provide a hardly graphitizable carbonaceous material used in a negative electrode material for nonaqueous electrolyte secondary batteries (for example, a lithium ion battery) having not only high charge capacity but also high charge-discharge efficiency and being fully charged to be used and a method for producing the same. To provide a negative electrode material for nonaqueous electrolyte secondary batteries comprising such a hardly graphitizable carbonaceous material, and a nonaqueous electrolyte secondary battery comprising such a negative electrode material for nonaqueous electrolyte secondary batteries and being fully charged to be used. A hardly graphitizable carbonaceous material, being a hardly graphitizable carbonaceous material for nonaqueous electrolyte secondary batteries fully charged to be used and having an oxygen element content of 0.25% by mass or less.
