CARBONACEOUS MATERIAL FOR NEGATIVE POLE ACTIVE SUBSTANCE OF NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, NEGATIVE POLE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND METHOD FOR PRODUCING CARBONACEOUS MATERIAL

摘要

The present invention relates to a carbonaceous material suitable for a negative pole active substance of a nonaqueous electrolyte secondary battery, a negative pole for a nonaqueous electrolyte secondary battery comprising the carbonaceous material, a nonaqueous electrolyte secondary battery having the negative pole, and a method for producing the carbonaceous material. The carbonaceous material of the present invention is the carbonaceous material for a negative pole active substance of a nonaqueous electrolyte secondary battery, wherein the carbonaceous material is derived from a plant, wherein a value of a half-value width of a peak in a vicinity of 1,360 cmin a Raman spectrum observed using laser Raman spectroscopy is 190 to 240 cm, and wherein a specific surface area determined in accordance with a nitrogen adsorption BET multipoint method is 10 to 100 m/g.
