    摘要： Provided herein are means for increasing the cycle characteristics of a lithium-ion secondary battery when silicon negative electrode active material is included as the negative electrode active material. The negative electrode for a lithium-ion secondary battery, according to one embodiment, is obtained by preparing a negative electrode active material slurry by mixing negative electrode active material, a binder material, and a binding properties improving agent in a solvent, applying the negative electrode active material slurry on the surface of a collector, and heat treating in anaerobic conditions. The negative electrode active material contains silicon as the main component thereof. The binder material is at least one kind selected from the group consisting of polyimide, polyamide and polyamideimide, and prepolymers of the same. The binding properties improving agent is at least one kind selected from the group consisting of polyvalent carboxylic acid and derivatives of the same, and polyvalent amine.
