Abstract
LiAMOobtained by replacing lithium in LiMOhaving a layered structure by an alkali metal having ion radius larger than that of lithium is used as a positive electrode active material. In this LiAMO, x satisfies the relation 0<x≦O.5, the above-mentioned A indicates the alkali metal having the ion radius larger than that of lithium (Li) (for example, sodium (Na) or potassium (K)) and M indicates a transition metal that can be tetravalent. Examples of the transition metal that can be tetravalent indicated by the above-mentioned M include manganese (Mn), molybdenum (Mo), titanium (Ti), platinum (Pt), iridium (Ir), ruthenium (Ru) and the like.
