Abstract:
To provide a negative electrode for nonaqueous electrolyte secondary batteries, by which the structural deterioration of the electrode is suppressed and cycle characteristics can be improved by absorbing the expansion and contraction of a silicon-based active material placed in the inside of a current collector made of porous metal, and a nonaqueous electrolyte secondary battery including the same. A negative electrode for nonaqueous electrolyte secondary batteries, having a current collector made of porous metal, and a negative electrode material placed in pores of the porous metal, the negative electrode material including a negative electrode active material including a silicon-based material; a skeleton forming agent including a silicate having a siloxane bond; a conductive additive; a binder; and a fibrous material.
