Abstract The structural instability of lithium‐based transition metal layered oxides during electrochemical cycling‐exacerbated by phenomena such as dissolution and phase transitions‐induces rapid capacity degradation, thus constraining their applicability in high‐energy‐density lithium batteries. While coating these materials can bolster stability, the employment electrochemically inactive coatings may inadvertently undermine energy storage performance, presenting a significant trade‐off. In response to this challenge, an innovative core‐shell cathode architecture is presented, wherein high entropy doped LiNi 1/6 Mn Al Ti Mo Ta O 2 serves shell nickel‐rich cobalt‐free 0.89 0.11 constitutes core, synthesized through simple two‐step co‐precipitation methodology (designated LHECNM). This high‐entropy preserves core's performance while effectively mitigating transformations ion dissolution, thereby enhancing robustness. Moreover, configuration significantly diminishes barrier for Li + diffusion, facilitating superior transport dynamics. Consequently, LHECNM demonstrates remarkable achieving discharge 201.57 mAh g −1 , commendable rate capability up 5C, impressive 92% retention over prolonged cycling. investigation elucidates promising paradigm design materials, offering profound insights advancement future technologies.

Abstract Ni‐rich cathodes are more promising candidates to the increasing demand for high capacity and ability operate at voltages. However, Ni content creates a trade‐off between energy density cycling stability, mainly caused by chemo‐mechanical degradation. Oxygen evolution, cation mixing, rock salt formation, phase transition, crack formation contribute degradation process. To overcome this problem, strategies such as doping, surface coating, core‐shell structures have been employed. The advantage of doping is engineer cathode surface, structure, particle morphology simultaneously. This review aims summarize recent advances in understanding mechanism role different dopants enhancing thermal stability overall electrochemical performance. pinning pillaring effects on suppressing oxygen transition introduced. It found that higher ionic radii enable reside particles, preserving refining suppress formation. Finally, effect Li ion diffusion, rate capability, long‐term discussed.

As a multi-electron system material, the excellent capacity and environmentally benign properties of Li2FeTiO4 cathodes make them attractive for lithium-ion batteries. Nevertheless, their electrochemical performance has been hampered by poor conductivity limited ion transport. In this work, synthesis Mg-doped Li2MgxFe1−xTiO4 (LiFT-Mgx, x = 0, 0.01, 0.03, 0.05) cathode materials was successfully achieved. We observed significant gains in interlayer spacing, ionic conductivity, kinetics. Hence, sample LiFT-Mg0.03 demonstrated charming initial (112.1 mAh g−1, 0.05 C), stability (85.0%, 30 cycles), rate capability (96.5 85.9%). This research provided precious insights into lithium storage with exceptional long-term potential to drive development next-generation energy technologies.
