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 Unraveling the fundamental mechanisms of sodium ion adsorption behavior is crucial for guiding design electrode materials and enhancing performance capacitive deionization systems. Herein, optimization systematically investigated through robust d–d orbital interactions within zinc‐doped iron carbide, facilitated by a novel liquid nitrogen quenching treatment. Liquid treatment can enhance coordination number, strengthen interactions, promote electron transfer, shift d‐band center Fe closer to Fermi level, thereby ions energy. Consequently, obtained material achieves superior gravimetric capacity 121.1 mg g −1 attractive cyclic durability. The highly competitive compared vast majority related research works in field deionization. Furthermore, adsorption/desorption are substantiated ex situ techniques, revealing dynamic atomic electronic structure evolutions under operational conditions. This work demonstrates that optimizing via modulation enabled an effective approach developing efficient materials.
