CARBONACEOUS MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY NEGATIVE ELECTRODE

The object of the present invention is to provide a carbonaceous material for a negative electrode of non-aqueous electrolyte secondary batteries having a great charge-discharge capacity, high charge-discharge efficiency, and an excellent charge-discharge cycle characteristic. [0002] The object can be solved by a carbonaceous material for a negative electrode of non-aqueous electrolyte secondary batteries, characterized in that an average (002) interlayer spacing d002 determined by X-ray diffractometry is 0.365 to 0.400 nm, a specific surface area determined by a BET method is 1 to 7 m/g, an average diameter is 5 to 25µm, a value of (D-D)/Dis 1.05 or less, and an exothermic peak does not emerge at a temperature range of 620°C or less in differential thermal analysis measured in an air atmosphere.
