Abstract
A negative electrode active material is provided, which can reduce and suppress ratio of expansion of silicon, provide enhanced conductivity, and realize superior charge/discharge cycle characteristic. The negative electrode material for secondary battery capable of occluding and releasing lithium consists of alloy particles having a silicon phase and a metal phase, and a carbonaceous material, in which crystallite size of the silicon phase is 10 nm or less, and the metal phase includes two or more kinds of metals alloying with silicon but not with lithium, and the carbonaceous material has crystallite size of 30 nm or more, and the carbonaceous material is present on the surface of, or within the alloy particles.
