Exploring redox activity in a LiCoPO4–LiCo2P3O10 tailored positive electrode for 5 V lithium ion batteries: rigid band behavior of the electronic structure and stability of the delithiated phase

Author affiliations

Abstract

The stability of the novel highly electronically conductive LiCoPO4–LiCo2P3O10 tailored polyphosphate is studied under electrochemical delithiation using quasi in situ depth-resolved synchrotron photoelectron spectroscopy, X-ray absorption spectroscopy and X-ray diffraction. The cathode material exhibits a rigid band behavior of the electronic structure and is stable in its fully delithiated state without amorphization in air.
