PROBLEM TO BE SOLVED: To provide a nonaqoues electrolyte battery with little deterioration of capacity in a charge and discharge cycle and with superb safety. SOLUTION: With the nonaqous electrolyte secondary battery, a positive active material includes a lithium metal oxide as expressed in a composition formula of LixMO2 (where, M is at least a kind selected from the group of Co, Ni, Fe, Al, Mg, Ti, Cr, Ga, Cu, and B, and (x) is in the range of: 0.4<=x<=1.0) and lithium hydroxide, the content of the latter to be 0.001 to 1 wt.% of the above lithium metal oxide. |
