Uncontrollable dendrite growth and sluggish ion-transport kinetics are considered as the main obstacles for further development of high-performance aqueous zinc ion batteries (AZIBs). Here, a nature-inspired separator (ZnHAP/BC) is developed to tackle these issues via hybridization biomass-derived bacterial cellulose (BC) network nano-hydroxyapatite particles (HAP). The as-prepared ZnHAP/BC not only regulates desolvation process hydrated Zn2+ ions (Zn(H2 O)62+ ) by suppressing water reactivity through surface functional groups, alleviating water-induced side-reactions, but also boosts homogenize flux, resulting in fast uniform Zn deposition. Remarkably, Zn|Zn symmetric cell with harvests long-term stability over 1600 h at 1 mA cm-2 , mAh endures stable cycling 1025 611 even high depth discharge (DOD) 50% 80%, respectively. Zn|V2 O5 full low negative/positive (N/P) capacity ratio 2.7 achieves superior retention 82% after 2500 cycles 10 A g-1 . Furthermore, Zn/HAP can be totally degraded within 2 weeks. This work develops novel nature-derived provides insights constructing separators toward sustainable advanced AZIBs.

Zn-based aqueous batteries (ZABs) hold great promise for large-scale energy storage applications due to the merits of intrinsic safety and low cost. Nevertheless, thorny issues metallic Zn anodes, including dendrite growth parasitic side reactions, have severely limited application ZABs. Despite encouraging improvements stabilizing anodes through surface modification, electrolyte optimization, structural design, fundamentally addressing inherent thermodynamics kinetics obstacles remains crucial in realizing reliable ZABs with ultrahigh efficiency, capacity, cyclability. The target this perspective is elucidate prominent status metal anode electrochemistry first from zincophilicity zincophobicity. Recent progress critically appraised key issues, special emphasis on trade-off between zincophilic zincophobic electrochemistry. Challenges prospects further exploration a are presented, which expected boost in-depth research practical advanced
