Abstract
A non-aqueous secondary battery contains a positive electrode, a negative electrode, a separator and a non-aqueous electrolytic solution. The positive electrode contains a layered structure lithium-containing compound oxide, or a spinel lithium-containing compound oxide containing manganese as an active material. The non-aqueous electrolytic solution contains at least one additive selected from a sulfonic acid anhydride, a sulfonate ester derivative, a cyclic sulfate derivative and a cyclic sulfonate ester derivative, and a vinylene carbonate or a derivative of the vinylene carbonate.
