Preparation and electrochemical investigation of Li2CoPO4F cathode material for lithium-ion batteries

We report the electrochemical characteristics of a novel cathode material Li2CoPO4F/C, which was prepared via a ceramic process. In cyclic voltammetry (CV) measurements, two reactions taking place at 4.81V and 5.12 V in the first anodic scan evolve to one broad oxidative peak in the subsequent cycle...
