  • Electrode Active Material and Lithium Secondary Battery
    Publication number: 20100183923
    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.
