PROBLEM TO BE SOLVED: To provide a carbon material which is superior in cycle performance as a negative electrode material of a lithium secondary battery, and effective in improvement of energy density. SOLUTION: The negative electrode of the lithium battery is formed of a carbonaceous material in which silver (Ag) is carried on the surfaces of carbon particles therein, and moreover, the surfaces are coated with a carbon material. Especially, it is preferred to coat the surfaces with the carbon material consisting of a heat decomposition product of hydrocarbon or a hydrocarbon derivative. COPYRIGHT: (C)2003,JPO |
