Unfortunately, the uneven deposition on the Zn anode promotes the growth of dendrites, and the corrosion of Zn by interfacial active water triggers a severe hydrogen evolution reaction (HER), which greatly hampers the further application of AZIBs. Therefore, a high-entropy (HE) electrolyte strategy is proposed to achieve a highly reversible Zn metal anode and an improved electrode/electrolyte interface (EEI). Specifically, this HE electrolyte achieves a water-poor solvation structure through N'N dimethylformamide (DMF) modulation of the solvation structure and accelerates Zn<sup>2+</sup> diffusion. The dynamic adsorption processes of benzylideneacetone (BDA) and DMF adsorption on the Zn anode strengthen the electrode-electrolyte interface, promoting uniform Zn deposition and interfacial stability are achieved. Consequently, Zn||Zn symmetric cells demonstrate cycle stability exceeding 1400 h, while Zn||Cu cells achieve an average Coulombic efficiency of 99.63% over 750 cycles. In addition, full cells assembled with this electrolyte demonstrates their great potential for practical applications.

Most strikingly, PtBi-NDs deliver a higher power density (8.3 mW cm<sup>−2</sup>) than Pt c-NCs in DEGFCs. The theoretical analysis and experimental measurements explain that the introduction of Bi element into Pt induces d–p orbital hybridization and promotes electron transfer from Bi to Pt, thereby facilitating C–C bond cleavage and boosting EGOR kinetics.
