Abstract Rechargeable zinc‐ion batteries (ZIBs) have recently attracted attention for applications in energy storage systems owing to their intrinsic safety, low cost, environmental compatibility, and competitive gravimetric density. To enable the practical of ZIBs, density must be equivalent existing commercial lithium‐ion batteries. acquire high‐energy density, increasing operating voltage battery is undoubtedly an effective method, which demands cathode material exhibit a high versus Zn 2+ /Zn, while matching highly reversible anode electrolyte with sufficiently wide electrochemical stability window. This review focuses on design strategies challenges towards high‐voltage ZIBs. First, basic electrochemistry ZIBs recent progress various materials including Prussian blue analogs, polyanionic compounds, metal‐based oxides are introduced. The corresponding countermeasures these discussed, further improve voltage, influence factors redox reaction, mechanism also illustrated. following section describes high‐performance anode, summarizes electrolytes that can help increase voltage. final outlines potential development
