METHOD OF PRODUCING NEGATIVE ELECTRODE, NEGATIVE ELECTRODE, AND LITHIUM-ION SECONDARY BATTERY

A method of producing a negative electrode includes at least the following (A) to (C): (A) mixing powder consisting of lithium titanate oxide particles, a binder, and a solvent to prepare a particle-dispersed liquid; (B) granulating powder consisting of graphite-based particles by using the particle-dispersed liquid to prepare wet granules; and (C) forming the wet granules into a negative electrode composite material layer to produce a negative electrode. The negative electrode composite material layer is formed so as to include the lithium titanate oxide particles in an amount not lower than 2 mass % and not higher than 15 mass % of the total amount of the graphite-based particles and the lithium titanate oxide particles.
