Method for producing composite, and negative electrode material for lithium ion battery
A production method for a composite of fine particles (A) and carbon particles (B), including the steps of: mixing fine particles (A) formed of a substance comprising at least one kind of Si, Sn, Al, Ge and In; and molten pitch, to obtain a mixture (1); pulverizing the mixture (1) to obtain a pulverized product (2a); dry-mixing the pulverized product (2a) and carbon particles (B) to obtain a mixture (3a); and firing the mixture (3a), followed by pulverization; or including the steps of: adding carbon particles (B) to the mixture (1), followed by dry mixing and pulverizing, to obtain a pulverized product (2b); and firing the pulverized product (2b), followed by pulverization.
