Title:
METHOD OF MANUFACTURING CARBON MATERIAL, CARBON MATERIAL, NEGATIVE ELECTRODE MATERIAL FOR SECONDARY CELL AND NON-AQUEOUS ELECTROLYTE SECONDARY CELL
Document Type and Number:
Japanese Patent JP2006264993
Kind Code:
A
Abstract:

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 a carbon material precursor which is one of a resin composition, a hardened material of the resin composition or a pre-carbonized material of them, (b) a step for supporting an alkali metal-containing compound on the surface of the carbon material precursor to make an alkali metal supported precursor, (c) a step for carbonizing the alkali metal supported precursor and (d) 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 negative electrode material for secondary cell.
