Rechargeable aqueous zinc-ion batteries (ZIBs) have emerged as promising candidates for energy storage due to their low cost, high safety, and theoretical density. However, the utilization of Zn anodes results in unsatisfied rate performance cycling stability dendrites, unsatisfactory stripping/plating efficiency, gas evolution. Herein, we propose a novel approach construct "rocking-chair" ZIBs with h-WO3 non-Zn anode address these issues. Metallic nonmetallic ion-doped (Cu-NWO) are designed deliver capacity an intercalation unique delocalized electronic structure active sites. Density functional theory calculations certify that Cu2+ preintercalation can strengthen electrochemical kinetics simultaneously reduce diffusion barriers on Zn2+ storage. The long cycle life density successfully realize self-powered electrochromic device, making them more suitable practical applications smart gird.

Abstract Recently, the development of Zn‐host materials in metal‐free aqueous Zinc ion batteries (AZIBs) has emerged as an effective strategy to address challenges uncontrollable dendrite growth and severe corrosion Zn anodes. Herein, layer‐by‐layer assembly conjugated polyimide nanocomposite (PTN‐MXene) through situ polymerization is proposed realize high energy density stability AZIBs. Specifically, unique layered structure abundant redox centers diketone‐based (PTN), combined with its structural compatibility MXene, enable formation a assembled 2D/2D heterostructure. This design ensures sufficient contact expands interlayer spacing facilitating faster electron/ion transport kinetics providing better access centers. Importantly, regulation behavior from H + or 2+ /Zn coinsertion PTN‐MXene achieved verified by different characterization techniques. Thus, anode exhibits specific capacity (283.4 mAh g −1 at 0.1 A ), excellent rate performance outstanding cycling performance. As proof‐of‐concept, full fabricated Prussian blue analogs cathode deliver 72.4 Wh kg exceptional over 2000 cycles.

The propensity of zinc (Zn) to form irregular electrodeposits at liquid-solid interfaces emerges as a fundamental barrier high-energy, rechargeable batteries that use anodes. So far, tremendous efforts are devoted tailoring interfaces, while atomic-scale reaction mechanisms and the related nanoscale strain electrochemical interface receive less attention. Here, underlying associated alloy investigate, using gold-zinc protective layer model system. Leveraging multiscale spatial resolution imaging techniques, it is observed gold element migration occurs universally plays pivotal role during galvanic process. Gold (Au) migrates from surface, where accumulates interface. remaining forms porous microstructure maintaining its interlayer position, leading relaxation plating.
