ABSTRACT:
Disclosed is a non-aqueous electrolyte secondary cell comprising a cathode made from a cathode compound that comprises a manganese oxide or a lithium-manganese composite oxide, a lithium metal anode or an anode comprising lithium or capable of doping and dedoping lithium ions, and a non-aqueous electrolyte, which is characterized in that the cathode compound contains an alkali metal carbonate of being from 0.5 to 20% by weight of the dry cathode compound. Even when used at high temperatures over room temperature for a long period of time, the cell is deteriorated little.
