摘要: The present invention provides a non-aqueous electrolyte secondary cell including: a cathode containing a manganese oxide or a lithium-manganese composite oxide; an anode containing a lithium metal, a lithium alloy, or a material capable of doping/dedoping lithium; and an electrolyte containing at least two electrolyte salts, one of which is LiBF4 contained in the range from 0.005 mol/l to 0.3 mol/l. This enables to increase the cycle characteristic, preventing deterioration of the cell characteristic caused by a repeated use.
