Materials and structural design for preferable Zn deposition behavior toward stable Zn anodes

Benefiting from the high capacity of Zn metal anodes and intrinsic safety aqueous electrolytes, rechargeable ion batteries (ZIBs) show promising application in post-lithium-ion period, exhibiting good safety, low cost, energy density. However, its commercialization still faces problems with Coulombic efficiency unsatisfied cycling performance due to poor Zn/Zn2+ reversibility that occurred on anode. To improve stability anode, optimizing deposition behavior is an efficient way, which can enhance subsequent striping limit dendrite growth. The a controlled kinetics-diffusion joint process affected by various factors, such as interaction between Zn2+ ions anodes, concentration gradient, current distribution. In this review, electrochemical perspective, we first overview factors affecting summarize modification principles. Subsequently, strategies proposed for interfacial 3D structural design well corresponding mechanisms are summarized. Finally, existing challenges, perspectives further development direction, outlook practical applications ZIBs proposed.
