MANUFACTURING METHOD OF METAL DOPED CARBONACEOUS THIN- FILM NEGATIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY CELL, METAL DOPED CARBONACEOUS THIN-FILM NEGATIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY CELL AND NONAQUEOUS ELECTROLYTE SECONDARY CELL USING ABOVE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a carbonaceous thin-film electrode doped with a metal element, which is excellent in charge and discharge cycle property, can realize high capacity, a negative electrode material for a nonaqueous electrolyte secondary cell and a nenaqueous electrolyte secondary cell, by a low temperature heat treatment process without relying on a binder forming method which causes lowering of operation reliability. SOLUTION: A secondary cell which has good charge and discharge cycle property and high capacity can be realized by using a metal-doped carbonaceous thin-film electrode, as a negative electrode of a nonaqueous electrolyte secondary cell, manufactured by coating it on a collector in heat treatment with coating solution which is made by dissolving or dispersing a compound including nonvolatile carbon and a metal compound into organic solvent.
