ABSTRACT:
A lithium secondary battery is provided with a positive electrode, a negative electrode, and a non-aqueous electrolyte prepared by dissolving a solute in a non-aqueous solvent wherein a positive electrode active material of said positive electrode is composed of lithium-manganese composite oxide having a spinel structure and lithium-transition metal composite oxide having a layer structure containing at least nickel and lithium salt having oxalato complex as anion is admixed to said non-aqueous electrolyte.
