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.

Abstract Considering the merits and shortcomings of conventional hydrogels in terms low‐temperature adaptability, a new type hydrogel electrolyte, reinforced by hydrogen bonding containing just 6.8% water, is fabricated. This film exhibits high ionic conductivity 3.9 mS cm −1 at room temperature maintains its flexibility even −40 °C. The hydrogel‐based quasi‐solid‐state cell shows good cyclic stability performance, retaining 80.3% initial capacity after 800 cycles. Furthermore, it performs well sub‐zero conditions, 89.6% −30 °C (0.5C) releasing 56.4 mAh g (0.1C). Notably, LTE‐based flexible full under 180° bending 15% stretching. can be attributed to polymer network with hydrophilic groups, which disrupts hydrogen‐bond networks original water molecules forms abundant interactions between chains molecules. These are crucial for improving adaptability. Overall, this work offers promising approach creating adaptable that used develop wearable energy‐storage devices.
