Abstract Zn dendrite growth and side reactions restrict the practical use of anode. Herein, design a novel 3D hierarchical structure is demonstrated with self–zincophilic dual–protection constructed by ZnO nanoparticles immobilized on carbon fibers (ZnO/Zn⊂CF) as versatile host surface. The unique frameworks abundant zinc nucleation storage sites can alleviate structural stress during plating/stripping process overpower moderating 2+ flux. Moreover, given dual protection design, it reduce contact area between active electrolyte, inhibiting hydrogen evolution reactions. Importantly, density functional theory calculations experimental results confirm that introduced O atoms in ZnO/Zn⊂CF enhance interaction overpotential. As expected, ZnO/Zn⊂CF–Zn electrode exhibits stable low polarization for 4200 h at 0.2 mA cm −2 mAh . Furthermore, symmetrical cell displays significantly long cycling life over 1800 h, even 30 fabricated full cells also show impressive performance when coupled V 2 3 cathodes.

Abstract The electrochemical performance of aqueous zinc metal batteries (AZMBs) is highly dependent on the electric double layer (EDL) properties at Zn electrode/electrolyte interface. Herein, a novel reconfigured EDL constructed via double‐charged theanine (TN) additive for super‐stable and deep‐rechargeable AZMBs. Experiments theoretical computations unravel that positively charged TN not only serves as preferential anchor to form water‐poor Helmholtz plane onto anode, but also its anionic end could coordinate with 2+ tailor solvation structure in diffusion further reconstruct inner H‐bonds networks, thus effectively guiding uniform deposition suppressing water‐induced side reactions. Consequently, Zn//Zn cells acquire outstanding cycling stabilities nearly 800 h high depth discharge 80%. Moreover, Zn//VOX full deliver substantial capacity retention (94.12% after 1400 cycles 2 A g −1 ) under practical conditions. Importantly, designed 2.7 Ah pouch cell harvests recorded energy density 42.3 Wh Kg 79.5 L –1 , remarkable 85.93% 220 50 mA .
