NEGATIVE ELECTRODE MATERIAL FOR NONACQUEOUS ELECTROLYTE SECONDARY BATTERY OF HIGH INPUT/OUTPUT CURRENT, METHOD FOR PRODUCING THE SAME AND BATTERY EMPLOYING NEGATIVE ELECTRODE MATERIAL

WIPO Patent Application WO/2005/098999

A1

A negative electrode material for a nonacqueous electrolyte secondary battery of high input/output current characterized in that the material is composed of a carbon material having an average layer face interval d₀₀₂ of the (002) face determined by X-ray diffraction in the range of 0.355-0.400 nm and a true density in the range of 1.50-1.60 g/cm³ and the capacity (A) in the battery voltage range of 0.3-1.0 V during discharge is 50 mAh/g or above by counter electrode lithium evaluation, and the ratio ((A)/(B)) of the capacity (A) to the capacity (B) in the battery voltage range of 0-1.0 V is 0.3 or above. The negative electrode material is hardly graphitized and has characteristics suitable as the negative electrode material for a nonacqueous electrolyte secondary battery of high input/output current used in HEV and the like.
