Here, the merits of porous Zn anodes were summarized, and a comprehensive overview of the recent advancements in the engineering of porous Zn metal anodes was provided, with a particular emphasis on the structural orderliness and critical role of porous structure modulation in enhancing battery performance.
While the majority of studies concentrate on developing effective protective layers for zinc surfaces, there is also significant interest in employing host materials that have three-dimensional (3D), porous, or ordered structures as anodes for zinc-ion batteries (ZIBs).
Among them, the structural design for zinc anode is relatively mature, which is generally believed to enhance the electroactive surface area of zinc anode, reduce local current density, and promote the uniform distribution of zinc ions on the surface of anode.
Although utilizing alternative materials such as alloys or ZnO as modification strategies for zinc battery anodes yields advantages in some respects, the limitations of this approach should also be fully considered.
