Abstract

Controlled off-stoichiometry is induced in 5 V olivine LiCoPO4 battery electrode material to overcome its insulating properties through the incorporation of lithium cobalt tripolyphosphate. An excellent electrochemical activity is achieved in this tailored carbon-free material. The electronic structure of the polyanionic compound, the Co2+/Co3+ redox energy, and quantification of the inductive effect are provided.
