Abstract
A non-aqueous electrolyte secondary battery includes a negative electrode, a positive electrode, and an electrolyte solution. The electrolyte solution contains at least one selected from the group consisting of ethylene carbonate, fluoroethylene carbonate, and vinylene carbonate. The negative electrode includes a negative electrode mixture layer. The negative electrode mixture layer contains a silicon-containing particle and a graphite particle. In a Log-differential pore volume distribution of the negative electrode mixture layer, the ratio of a Log-differential pore volume at a pore diameter of 2 μm to a Log-differential pore volume at a pore diameter of 0.2 μm is within a range of 10.5 to 33.1.
