摘要：
A positive electrode active material provided in the present invention is characterized in that it is substantially formed of a lithium nickel cobalt manganese composite oxide and that a molar content ratio (NiIII/NiII) of bivalent nickel atoms (NiII) and trivalent nickel atoms (NiIII) of nickel atoms constituting the composite oxide is 0.15≦(NiIII/NiII)≦0.95.
