Abstract
Disclosed are an electrode material for a non-aqueous solvent secondary battery, which comprises a composite carbonaceous material in which to the surface of a graphite 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 the graphite carbonaceous material, and a process for preparing an electrode material for a non-aqueous solvent secondary battery, which comprises the steps of introducing a slurry obtained by adding an aromatic organic solvent to a mixture of graphite carbonaceous material particles and an organic substance and adjusting viscosity to 10000 cp or lower into a mixing and stirring apparatus having a reaction room which has a paddle rotatable by a shaft in an inner portion thereof, the inner wall surface of the reaction room being formed substantially along the outermost line of rotation of the paddle and also, being provided a mechanism of deaerating a solvent, heating it to a temperature of the boiling point of the solvent or higher and lower than 600.degree. C. while stirring to prepare a solid intermediate a…
