摘要	Ni-rich layered oxide cathodes have shown promise for high-energy lithium -ion batteries (LIBs) but are usually limited to mild environments because of their rapid performance degradation under extreme temperature conditions (below 0 degrees C and above 50 degrees C). Here, we report the design of F/Mo co-doped LiNi 0.8 Co 0.1 Mn 0.1 O 2 (FMNCM) cathode for high-performance LIBs from -20 to 60 degrees C. F - doping with high electronegativity into the cathode surface is found to enhance the stability of surface lattice structure and protect the interface from side reactions with the electrolyte by generating a LiF-rich surface layer. Concurrently, the Mo 6+ doping suppresses phase transition, which blocks Li + /Ni 2+ mixing, and stabilizes lithium -ion diffusion pathway. Remarkably, the FMNCM cathode demonstrates excellent cycling stability at a high cutoff voltage of 4.4 V, even at 60 degrees C, maintaining 90.6% capacity retention at 3 C after 150 cycles. Additionally, at temperatures as low as -20 degrees C, it retains 77.1% of its room temperature capacity, achieving an impressive 97.5% capacity retention after 500 cycles. Such stable operation under wide temperatures has been further validated in practical Ah-level pouch-cells. This study sheds light on both fundamental mechanisms and practical implications for the design of advanced cathode materials for wide-temperature LIBs, presenting a promising path towards high-energy and long-cycling LIBs with temperature adaptability.
