NEGATIVE ELECTRODE FOR USE IN NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY INCLUDING SAME

Provided are a negative electrode that is for use in a non-aqueous electrolyte secondary battery, includes a porous metal body as a current collector, contains a skeleton-forming agent highly infiltrated in the current collector so that It is less likely to suffer from structural degradation and provides improved cycle durability; and a non-aqueous electrolyte secondary battery including such a negative electrode. The negative electrode for use in a non-aqueous electrolyte secondary battery includes a current collector including a porous metal body; a first negative electrode material disposed in pores of the porous metal body and including a conductive aid, a binder, and a negative electrode active material including a silicon-based material; and a second negative electrode material disposed in pores of the porous metal body and including a skeleton-forming agent including a silicate having a siloxane bond.
