High-voltage performance of LiCoO^sub 2^ cathode studied by single particle microelectrodes –influence of surface modification with TiO^sub 2

The LiCoO2 particle with TiO2 coating presents improved columbic efficiency, overcharge performance, rate capability and cycling stability at high voltage. To gain deeper insight into the performance improvement mechanism of the TiO2-coated LiCoO2 cathode materials, the first-principles calculation...
