Abstract In the past few years, aqueous zinc‐metal batteries (ZMBs) have gained much attention and can be regarded as a potential alternative to lithium‐metal owing their high safety, nature of abundance, environmental sustainability. However, several challenges persist, including dendrite formation, corrosion, unwanted side reactions, before ZMBs fully utilized in practical applications. To circumvent these issues, anode free (AFZMBs) emerged next‐generation energy storage system. This review provides comprehensive analysis recent developments AFZMBs, working mechanisms, advantages over conventional ZMBs, for implementation. It also highlights key strategies, current collector modification, electrolyte engineering, 3D printing techniques enhance zinc deposition uniformity cycling stability. The explores how technology revolutionize design advanced collectors zinc‐rich cathodes, optimizing material utilization enhancing battery performance. Finally, with future perspective AFZMBs is concluded, highlighting need further research address existing bottlenecks unlock storage.
