NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY AND VEHICLE

摘要

The purpose of the present invention is to provide a non-aqueous electrolyte secondary battery having further improved cycle properties using a sulfur-based positive electrode active material. The present invention relates to a non-aqueous electrolyte secondary battery comprising a positive electrode, a negative electrode and a non-aqueous electrolyte, wherein the positive electrode contains a sulfur-based positive electrode active material that contains carbon (C) and sulfur (S) as a positive electrode active material and the negative electrode contains metal lithium or metal sodium as a negative electrode active material.
