NON-AQUEOUS SOLVENT SECONDARY BATTERY ELECTRODE MATERIAL ANDPROCESS FOR PREPARING THE SAME

摘要

This invention relates to an electrode material to be used for a non-aqueous solvent secondary battery and a process for preparing the same,-particularly to an electrode material having a multiphase structure and a process for preparing the same. According to an aspect of the present invention, there is provided an electrode material for a non-aqueous solvent secondary battery, which comprises a composite carbonaceous material in which to the surface of a graphite-like carbonaceous material is attached a carbonized material of an organic substance in an amount to give a carbon residue of 12 parts by weight or less and 0.1 part by weight or more based on 100 parts by weight of said graphite-like carbonaceous material and the graphite-like carbonaceous material has a plane spacing d002 of a (002) plane of 0.340 nm or less and a crystallite size Lc in a c axis direction of 50 nm or more.
