| description | There is provided a nonaqueous electrolyte secondary battery in which lithium deposition on the surface of a negative electrode is suppressed. The nonaqueous electrolyte secondary battery includes a positive electrode, a negative electrode having a negative electrode active material mixture layer containing a negative electrode active material, and a nonaqueous electrolyte. The negative electrode active material contains coated graphite particles having surfaces coated with a coating layer which contains first amorphous carbon and second amorphous carbon. The negative electrode active material mixture layer contains the coated graphite particles and third amorphous carbon as a conductive agent. The nonaqueous electrolyte contains a difluorophosphate salt and a lithium salt having an oxalate complex as an anion. |
