Abstract
Electrode active material that is used together with an electrolyte solution having an electrolyte decomposition potential Ve is represented by the general expression LixFeMyO2 and is amorphous. In the expression, x and y are values which independently satisfy 1<x≦2.5 and O<y≦3, respectively, and z=(x+(valence of Fe)+(valence of M)×y)/2 to satisfy stoichiometry, and M represents one or two or more types of glass former element. The average electronegativity of M is less than (Ve+6.74/5.41.
