CARBON MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY NEGATIVE ELECTRODE |
摘要 |
An object of the present invention is to provide a carbonaceous material for a negative electrode for producing a nonaqueous electrolyte secondary battery capable of rapid charge and discharge and having excellent rate characteristics (output characteristics) while maintaining a large discharge capacity. The problem described above can be solved by a carbonaceous material for a nonaqueous electrolyte secondary battery negative electrode of the present invention obtained by heat-treating a non-graphitizable carbon precursor which is pulverized and contains from 13 to 80 wt.% of a volatile component. With the present invention, it is possible to provide a carbonaceous material for a nonaqueous electrolyte secondary battery negative electrode, whereby a nonaqueous electrolyte secondary battery having a large charge-discharge capacity and having excellent rate characteristics can be produced. |
