Method of preparing a negative electrode material for non-aqueous electrolyte secondary battery

A simple manufacturing process as compared with the conventional method, a method of manufacturing a negative electrode material for a nonaqueous electrolyte secondary battery having a conventional equivalent battery characteristics. Thermal Weight forming treatment and petroleum after or coal solidified body was cooled to solidify the to below the softening point pitch was triturated average particle size below (median diameter) 60 [mu] m to form a finely divided pitch, and then the pulverulent pitch by compression molding at a pressure of 20~100MPa or 0.1~6MN / m to form a porous compacts, subjecting the porous compacts to infusibilization.
