Uncontrollable dendrite growth and severe parasitic side reactions on Zn electrodes pose formidable challenges for the application of aqueous Zn-ion batteries. Herein, we engineered a biomimetic inorganic–organic protective layer composed alginic acid lithium magnesium silicate to enhance stability reversibility electrode. This not only diminishes free water concentration near surface but also creates negatively charged ion microchannels transport ions modulate solvation structure. Moreover, robust Mg-SiO2 interphase with high Young's modulus strong zincophilicity can be formed between electrode layer, facilitating uniform deposition along Zn(002) planes. Consequently, this allows achieve impressive cycling lifespan 5500 h at 1 mA cm–2/1 mAh cm–2 Coulombic efficiency 99.5% delivers remarkable cyclability up 8000 cycles in Zn||V2O5 full cells.

Abstract Aqueous zinc‐ion batteries (AZIBs) are of interest in next‐generation energy storage applications owing to their safety, environmental friendliness, and cost‐effectiveness. Vanadium‐based oxides promising cathodes for AZIBs due appropriate structure multielectron redox processes. Although hundreds studies devoted understanding the mechanisms developing high‐performance vanadium‐based cathodes, many puzzles controversies still exist, especially regarding two representative by‐products, basic zinc salt (BZS) pyrovanadate (ZVO). BZS ZVO often observed on cathode anode during cycling, directly affecting battery performance. However, by‐products’ controversial unclassified insights unclear have severely limited Zn‐V batteries’ progress. Therefore, this review aims exhaustively elucidate “past present” by‐products following a logical sequence origin, role, inhibition strategy, prospect. Notably, incorporates substantial comments understandings long‐neglected issues related BZS‐related ZVO‐related dissolution mechanisms. This is expected provide scientific guidelines future optimization commercialization batteries.

Solid polymer electrolytes (SPEs) hold substantial potential for enabling highly flexible and stable zinc-ion batteries (ZIBs) due to their nearly anhydrous nature. However, the development of SPEs is still hindered by poor zinc-ion-transport kinetics. Herein, utilizing CALF-20 as both a filler functional coating, bilayer solid-state electrolyte (BSSE) was designed. On one hand, intermediate filled poly(ethylene oxide) hybrid gel demonstrates strong interaction with CF3SO3- anions, thus promoting Zn2+ dissociation transmission. other outer single layer supports ions abundant transmission paths low migration energy barrier, which doubly accelerates ion at interface. This internal/surface dual acceleration strategy allows BSSE deliver high ionic conductivity transference number. Both Zn∥Zn symmetric Zn∥MnO2 full cells exhibit an obvious prolonged cycle life. sheds light on design high-ionic-conductivity, steady, practical ZIBs.

Abstract Aqueous Zn metal batteries (AZMBs) have appealing advantages, including good safety, low cost, and high volumetric energy density. However, serious parasitic reactions dendrite growth at anodes hinder practical applications of AZMBs. Here, a nature‐inspired strategy is proposed to improve using plant‐cell derivatives as additives for ZnSO 4 electrolytes. In the electrolyte, TEMPO (2,2,6,6‐tetramethylpiperidine‐1‐oxyl)‐oxidized cellulose nanofibers (TOCN) calcium lignosulfonate (CL) with specific functional groups modulate 2+ solvation structure. More importantly, they reform cell membrane/wall‐like layer mechanical strength selective transmission/plating on anode surface, which enables uniform deposition alleviates side reactions. As result, symmetric cells dual‐additive electrolyte exhibit highly reversible dendrite‐free stripping/plating behavior over 2000 500 h 2 mA cm −2 /1 mAh 10 /10 , respectively. Furthermore, Zn//NH V O full shows cycling stability 300 cycles negative/positive (N/P) ratio. A density 92.9 Wh kg −1 can be delivered limited metallic consumption, showing that has prospects use.
