To provide a method of manufacturing a carbon material capable of manufacturing a negative electrode material for a non-aqueous electrolyte secondary cell having excellent charge discharge characteristics, the carbon material obtained by the manufacturing method, the negative electrode material for the secondary cell using the carbon material and a non-aqueous electrolyte secondary cell.
The method of manufacturing the carbon material has (a) a step for preparing an alkali metal-containing carbon material precursor by mixing a resin composition with a alkali metal-containing compound, (b) a step for carbonizing the alkali metal-containing carbon material precursor and (c) a step for washing the treated material after the carbonization to substantially remove the alkali metal component existing at least on the surface part of the treated material, The carbon material is manufactured by this method. The secondary negative electrode material contains the carbon material. The non-aqueous electrolyte secondary cell uses the secondary cell negative electrode material.
