Conversion electrodes offer higher reversible capacity and lower cost than conventional intercalation chemistry electrodes, but suffer from kinetic limitation large volume expansion. Despite significant efforts, developing conversion with fast charging capability extended lifespan remains challenging. Here, by leveraging the advantages of high-entropy doping morphology tailoring, we develop a hierarchical micro/nanostructured sulfoselenide Cu0.88Sn0.02Sb0.02Bi0.02Mn0.02S0.9Se0.1 electrode entropy-driven fast-charging capability. When used as negative material for sodium-ion batteries, it achieves stable cycle life 10,000 cycles at 30 A g-1 high 365.7 mAh under in 13 seconds 100 g-1. Moreover, also demonstrates cycling good rate positive lithium metal achieving 37 that is comparable state-of-the-art layered cathodes. High-entropy characterized its robust crystal structure, low ion diffusion barrier, effective suppression side reactions electrolytes during cycling. Importantly, transmission X-ray microscopy affirms chemical stability HESSe, which underpins performance.
