Abstract
Providing a negative-electrode material for nonaqueous-electrolyte secondary battery, the negative-electrode material including lithium silicate particles coated by a carbonaceous substance, a production process for the same, a negative electrode for nonaqueous-electrolyte secondary battery, and a nonaqueous-electrolyte secondary battery. A negative-electrode material for nonaqueous-electrolyte secondary battery includes lithium silicate particles having a surface at least some of which is coated by a carbonaceous substance formed by heating a carbon-containing compound at a thermal decomposition temperature of the carbon-containing compound or more and 1,100±° C. or less, the carbon-containing compound being a solid at ordinary temperature and exhibiting a zeta-potential absolute value being 60 or more against N-methyl-2-pyrrolidone (or NMP).
