The inventors provide a non-aqueous electrolyte secondary battery in which the mass ratio of positive active materials, i.e., the mass ratio of lithium cobalt oxide to lithium manganese oxide is adjusted to improve both energy density and safety and in which a solvent containing ethylene carbonate (EC) and propylene carbonate (PC) is used so that the EC content and the PC content can be controlled to prevent swelling and improve both safety at overcharge and safety at a high temperature. |
