Ni-rich cathode materials, one of the most promising cathodes for high-energy lithium-ion batteries, are still suffered from interfacial instability and bulk degradation. Herein, Zr-doped and Li6Zr2O7-coated LiNi0.8Co0.1Mn0.1O2 cathode, and Zr-doped Li6Zr2O7-LiNi0.8Co0.1Mn0.1O2 composite are successfully pre-pared via a smart one-step calcination process. The attained dual-modified architecture allows the optimized sample exhibiting enhanced rate performance while maintaining long-term stability at room temperature (82.13% after 200 cycles at 1 C rate) and even at elevated temperature.
