Using High‐Entropy Configuration Strategy to Design Spinel Lithium Manganate Cathodes with Remarkable Electrochemical Performance

and 90.55% after 500 cycles at 1 C. The as-prepared HE-LMO displays favorable cycling stability, significantly surpassing the pristine sample. Furthermore, theoretical calculations strongly support the above finding. HE-LMO has a higher and more continuous density of states at the Fermi energy level and more robust bonded states of the electrons among the Mn─O atom pairs. This research contributes to the field of high-entropy doping modification and establishes a facile strategy for designing advanced spinel manganese-based lithium-ion batteries (LIBs).
