Doping is indispensable for ensuring the long-term cycling stability of Ni-rich layered cathodes. However, using a single type dopant limits development stable, high-energy cathode material in shot. In this study, dual doping strategy Al3+ and Nb5+ ions was adopted to improve Li[Ni0.92Co0.04Mn0.04]O2 (NCM92) cathode; fortifies crystal structure, while optimized morphology primary particles. The not only combines benefits both dopants simultaneously but also demonstrates excellent performance enhancement through synergistic effects. Li[Ni0.905Co0.04Mn0.04Al0.005Nb0.01]O2 (AlNb-NCM92) cathode, which developed Al Nb, exhibited remarkable stability, retaining 88.3% its initial capacity even after 1000 cycles. This result suggests that needs comprehensively consider structure microstructure maximize materials.

Abstract The irreversible deterioration of electrochemical performance in Ni‐rich cathode materials, attributed to crack propagation and undesired side reactions, poses a critical barrier the further development high‐energy power batteries for electrical vehicles (EVs). Herein, concentration gradient strategy is proposed synthesizing with enhanced mechanical stability address issues related structural deterioration. Notably, structure contributes superior strength secondary particles due radially orientated primary resulted from Mn composition grading, which effectively alleviate internal strain caused by changes fatigue destruction during successive cycling. Moreover, Mn‐rich surface minimizes parasitic reactions at electrode–electrolyte interface. Benefitting above, sample can deliver ≈180.1 mA h g −1 1 C retain 96.2% its initial discharge capacity after 100 cycles. This work demonstrates that simultaneously improve chemical stabilities offers feasible way designing stable lithium‐ion high energy density.

Abstract Owing to its abundant manganese source, high operating voltage, and good ionic diffusivity attributed 3D Li‐ion diffusion channels. Spinel LiMn 2 O 4 is considered a promising low‐cost positive electrode material in the context of reducing scarce elements such as cobalt nickel from advanced lithium‐ion batteries. However, rapid capacity degradation inadequate rate capabilities induced by Jahn–Teller distortion dissolution have limited large‐scale adoption spinel for decades.

Abstract Substantial endeavors are dedicated to advance the electrochemical performance of Ni‐rich Li[Ni 1− x − y Co Mn ]O 2 (NCM) and Al (NCA) cathode, with a particular focus on doping, aimed at addressing cycling durability thermal stability cathodes. is widely considered an attractive dopant because its abundance considerably lower cost than other candidates. However, despite long history research, role doping remains poorly understood, confined historical level, associated crystal structural chemical aspects. Herein, beyond classical redefined, particularly in terms cathode microstructure. Introducing excess during calcination significantly engineers nano‐ micro‐level features peripheral grains 0.910 0.079 0.011 cathode. The microstructural modification achieved by 4 mol% improves extending capacity retention up 76.5% after 1000 cycles under fast charging conditions (3 C 45 °C). Hence, providing alternative approach redesign offers significant step toward sustainable development high‐performance z (NCMA) cathodes for next‐generation lithium‐ion batteries.
