Achieving high energy density and long cycle life in alloy-type anodes remains a significant challenge due to the large volume changes during cycling. Here, we introduce high-entropy engineering approach using SnSb-based oxides codoped with Ti Al (SSBTA-600), designed promote formation of efficient oxygen vacancies at calcination temperature 600 °C. This results remarkable performance capacity 1012 mAh g-1 0.5 A 297 5 after 500 cycles, superior retention 99% 83.5%, respectively. LiFePO4||SSBTA full cell achieves 134 100 cycles 89.4% retention, demonstrating its practical potential for lithium-ion batteries. The concentration SSBTA-600, induced by multivalency Al, is validated electron paramagnetic resonance (EPR) X-ray absorption spectroscopy (XAS). significantly improves cyclic stability high-rate provides promising strategy enhancing anodes.
