Abstract

A non-aqueous electrolyte secondary battery includes a non-aqueous electrolyte and an electrode body in which a positive electrode plate and a negative electrode plate are layered with a separator interposed therebetween. The positive electrode plate contains a phosphate compound. The negative electrode plate contains a graphite-based material, an amorphous/non-crystalline carbon material, and a rubber-based binder. The ratio of the coverage of the rubber-based binder on the amorphous/non-crystalline carbon material to the coverage of the rubber-based binder on the graphite-based material is more than 0 and 0.5 or less.
