Abstract Zinc bromine flow battery (ZBFB) is a promising technology for stationary energy storage. However, challenges specific to zinc anodes must be resolved, including dendritic growth, hydrogen evolution reaction, and the occurrence of “dead zinc”. Traditional additives suppress side reactions dendrite formation by altering solvation structure Zn 2+ adsorbing onto surface through only limited number zincophilic sites, resulting in weak adsorption on metal potential inability simultaneously optimize ions. Obviously, increasing sites additive can significantly enhance interaction with zinc. Herein, we propose strong chelate, ethylenediamine tetramethylene phosphonic acid (EDTMPA) as additive, which boasts six potent not promotes water‐deficient inner Helmholtz plane but also plays crucial role restructuring environment . As result, symmetric EDTMPA exhibited exceptional coulombic efficiency 99.4 % over 800 cycles, surpassing previous studies significant margin. Furthermore, assembled ZBFB has showcased dendrite‐free enduring cycling 400 cycles at 80 mA cm −2

Aqueous alkaline zinc–iron flow batteries (AZIFBs) offer significant potential for large-scale energy storage. However, the uncontrollable Zn dendrite growth and hydrogen evolution reaction (HER) still hinder stable operation of AZIFB. Herein, dense Cu@Cu6Sn5 core–shell nanoparticles are constructed on graphite felt (Cu@Cu6Sn5/GF) to induce zinc plating inhibit HER simultaneously. The charge transfer within Cu6Sn5 alloy shell provides a negative Cu, increasing its ability attract Zn. lack electrons in Sn makes it difficult undergo HER, which is confirmed by total internal reflection imaging method. Meanwhile, Cu core can increase conductivity between interface GF Cu@Cu6Sn5. As result, Cu@Cu6Sn5/GF electrode demonstrates superior cycling performance AZIFB with an average Coulombic efficiency 99.3% 700 cycles achieves maximum power density 487.6 mW cm–2. This strategy also be applied other Zn-based batteries.

Abstract Zinc‐based flow batteries (ZFBs) are promising for large‐scale energy storage applications. However, the formation of Zn dendrites and limited areal capacity ZFBs hinder their further development. In this study, we designed a digital light‐processed 3D‐printed pillar array pore ceramic membrane (3DPC) to construct with high long cycle life. The design reduces transmembrane resistance by ~60% facilitates K + Na transport. arrays serve as electrolyte reservoirs regulate interfacial ion distribution provide sufficient space deposition. Moreover, surface hardness ceramics up 1.46 GPa provides against zinc dendrite damage. Furthermore, cell based on 3DPC exhibits stable efficiency exceeding 79% during operation over 950 h at an 280 mAh cm −2 . This study demonstrates potential membranes metal‐based batteries.

Aqueous Zn-based flow batteries often face issues such as poor reversibility and short lifespan due to irregular Zn deposition detrimental side reactions. To address these challenges, we developed a zwitterionic gemini additive, N,N′-bis(3-propanesulfonic acid)-3,3′-bipyridinium (SPr-Bpy), enhance plating/stripping behavior optimize the Zn2+ solvation structure. The dual sulfonate groups influence shell anchor SPr-Bpy surface through multi-site interactions. Additionally, bipyridinium structure forms an electrostatic shielding layer, suppressing excessive accumulation, promoting uniform deposition, thus mitigating dendrite formation hydrogen evolution. Consequently, Zn||Zn symmetric cells exhibit impressive of 250 h, while Zn||Cu asymmetric achieve high average Coulombic efficiency 99.8% over 450 cycles.
