Abstract
A method for manufacturing negative electrode material particles includes the steps of: mixing silicon oxide granules with a powder of a pitch without using any liquid organic solvents, so as to obtain a mixture; and heating the mixture at a heating rate ranging from 0.65° C./min to 1.25° C./min to a carbonization temperature of not lower than 600° C. for not less than 5 hours, so that the thus melted pitch is carbonized and forms a carbon film on a surface of each of the silicon oxide granules, thereby obtaining the negative electrode material particles. Each of the negative electrode material particles has a mean particle size ranging from 2 μm to 11 μm.
