Abstract
A positive electrode active material including lithium (Li), nickel (Ni), manganese (Mn) and a transition metal that can be in the hexavalent state is used. As the transition metal that can be in the hexavalent state, for example, one or both of tungsten (W) and molybdenum (Mo) can be used. As the positive electrode active material including a plurality of materials as mentioned above, LiNi0.5Mn0.5O2 can be used. As a negative electrode, a carbon material or a silicon material capable of storing and releasing lithium ions can be used.
