NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

A nonaqueous electrolyte secondary battery includes a positive electrode containing a lithium transition metal oxide as a positive electrode active material, a negative electrode containing a carbon material as a negative electrode active material, and a nonaqueous electrolyte. The lithium transition metal oxide contains W and Si, and W and Si adhere to the surface of the carbon material constituting the negative electrode active material. The amount of W adhering to the surface of the carbon material is 2 times or less in terms of a molar ratio to the amount of Si adhering to the surface of the carbon material.
