Abstract
A non-aqueous electrolyte battery includes a non-aqueous electrolyte containing an electrolytic salt and a non-aqueous solvent, a positive electrode, and a negative electrode having a negative active material that intercalates/deintercalates lithium ions at a potential not lower than 1.2 V relative to the potential of lithium, wherein a film coat having a carbonate structure and a thickness of not less than 10 nm exists on the surface of the negative electrode. A non-aqueous electrolyte battery is operated in a region of potential of the negative electrode higher than 0.8 V relative to the potential of lithium.
