Lithium cobalt oxide (LiCoO2) particles are modified using rotor blade grinding and re-annealing and used as the active electrode material versus lithium in the 3-0 V potential interval, in which a maximum capacity of 903 mA hg(-1) is achieved. X-ray absorption near edge structure spectra reveal the complete reduction of Co+ to Co metal at 0 V. Cell recharge leads to an incomplete reoxidation of cobalt. A maximum reversible capacity of 812 mAhg(-1) is obtained, although a poor capacity retention upon prolonged cycling may limit its application.
