| 英文摘要 | The strategy of multiphase engineering has garnered significant interests due to the potential for achieving high energy density and long cycling lifespan towards layer-structured oxide cathode materials. However, challenges such as phase separation arising from different expansion coefficients among phases under high voltage or during prolonged cycling have been a concern. Bridging effect from a spinel phase was in-situ introduced herein via a target element quenching process. The introduced stabilized spinel-bridged phase can create a structural confinement between the O3 and P2 phases and realize interface reconstructing simultaneously by target- element optimization. Based on the experimental and computational results, the multiphase riveting- structured O3/spinel/P2 triphasic structure provides a structural constraint and alleviates the internal stress, which can suppress detrimental irreversible phase changes to enhance the structural reversibility and stability. Beneficial to the optimized ions high diffusion kinetics and lower diffusion barriers, the obtained O3/spinel/P2Na 0.98 Ni 0.3 Cu 0.1 Ti 0.05 Mo 0.05 Mn 0.5 O 2-delta S delta demonstrates an impressive initial capacity of 178.6 mAh g-1 at a current density of 10 mA g-1, with a remarkable capacity retention rate of 86.65% over 200 cycles at 50 mA g-1. This innovative approach offers a new solution for preparing structurally stable, high-performance layer-structured oxides with satisfied cycling performance for sodium-ion batteries. |
