1. , a kind of non-aqueous electrolyte battery, but but be to possess occlusion to emit the positive pole occlusion of lithium and emit the negative pole of lithium and the non-aqueous electrolyte battery of nonaqueous electrolytic solution, it is characterized in that in the positive active material that constitutes described positive pole, using being selected from composition formula LiNi cMn dCo 1-c-dO 2Wherein:

  • 0<




    0.6, the lithium nickel cobalt manganese composite oxides of expression and the mixture of complex Li-Mn-oxide, and make above-mentioned nonaqueous electrolytic solution contain saturated cyclic carbonic ester and unsaturated cyclic carbonic ester at least with carbon-carbon double bond, and described content with unsaturated cyclic carbonic ester of carbon-carbon double bond is the positive electrode capacity for every 1mAh, 1.0 * 10 -8

    2.4 * 10 -4The scope of g.
