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. In this study, 1.98 Mg 0.005 Ti Sb Ce (HE‐LMO) with remarkable interfacial structural cycling stability developed based on complex concentrated doping strategy. The initial discharge retention HE‐LMO are 111.51 mAh g −1 90.55% after 500 cycles at 1 C. as‐prepared displays favorable stability, significantly surpassing pristine sample. Furthermore, theoretical calculations strongly support above finding. has higher more continuous density states Fermi energy level robust bonded electrons among Mn─O atom pairs. This research contributes field high‐entropy modification establishes facile strategy designing manganese‐based batteries (LIBs).
