Constructing compatible interface between Li7La3Zr2O12 solid electrolyte and LiCoO2 cathode for stable cycling performances at 4.5 V

A compatible interface between Li₇La₃Zr₂O₁₂ and LCoO₂ has been constructed through a facile surface modification strategy, which significantly improves the cycling stability of LCoO₂ cathode material at a high cut-off voltage of 4.5 V.
