Abstract
A non-aqueous electrolyte secondary battery includes at least a negative electrode including a negative electrode mixture, a positive electrode, and an electrolytic solution including an electrolyte and a solvent. The negative electrode mixture includes a negative electrode active material powder, the negative electrode active material powder includes a carbon-based material and a silicon-based material, a mixing ratio of the carbon-based material to the silicon-based material (carbon-based material (mass %)/silicon-based material (mass %)) is 90 mass %/10 mass % to 0 mass %/100 mass %.
