摘要
A method for manufacturing a graphite powder for a negative electrode material for a lithium-ion secondary battery, which includes a process of pulverizing a graphite precursor, and subjecting a mixture of the pulverized graphite precursor and an alkaline compound to graphitization treatment by heating the mixture at 2,800 to 3,500° C. Also disclosed is a graphite powder obtained by the manufacturing method, a negative electrode for a lithium-ion secondary battery containing the graphite powder and a lithium-ion battery provided with the negative electrode.
