Abstract Separators are critical components of zinc‐metal batteries (ZMBs). Despite their high ionic conductivity and excellent electrolyte retention, the widely used glass fiber (GF) membranes suffer from poor mechanical stability cannot suppress dendrite growth, leading to rapid battery failure. Contrarily, polymer‐based separators offer superior strength facilitate more homogeneous zinc (Zn) deposition. However, they typically sluggish ion transport kinetics wettability by aqueous electrolytes, resulting in unsatisfactory electrochemical performance. Here a dehydroxylation strategy is proposed overcome above‐mentioned limitations for polyvinyl alcohol (PVA) separators. A dehydroxylated PVA‐based membrane (DHPVA) synthesized at relatively low temperature highly concentrated alkaline solution. Part hydroxyl groups removed and, as result, hydrogen bonding between PVA chains, which deemed responsible kinetics, minimized. At 20 °C, DHPVA reaches 12.5 mS cm −1 , almost 4 times higher than that PVA. Additionally, effectively promotes uniform Zn deposition, significantly extended cycle life reduced polarization, both a/symmetric (Cu/Zn Zn/Zn) full cells (Zn/NaV 3 O 8 ). This study provides new, effective, yet simple approach improve performance ZMBs.

Aqueous zinc-ion batteries (AZIBs) with Zn metal as the anode have great potential for large-scale energy storage due to their unique advantages. However, anodes face unfavorable conditions such hydrogen evolution reaction (HER) and dendrite growth, which limit practical application of AZIBs. We constructed a calcium alginate (CA) hydrogel protective layer on foil surface. The carboxyl hydroxyl groups in CA can form bonds H2O inhibit HER. Meanwhile, coating also promotes desolvation process Zn(H2O)62+, results uniform dispersion Zn2+ flux. homogenize electric field distribution surface growth dendrites. Therefore, CA-Zn symmetric be stably cycled 2200 h at 0.5 mA cm–2, showing excellent cycling performance. Overall, introduction effectively optimized faced by anode.

Abstract The issues of active iodine dissolution and polyiodide shuttle severely hinder the development zinc‐iodine batteries (ZIBs). Binder engineering is considered a valid strategy to kill two birds with one stone. Herein, sodium lignosulfonate (LS), an important derivative lignin, optimized as neotype binder for fabrication iodine‐loading cathode. Owing existence ‐SO 3 Na group, electrostatic potential LS molecule contains both negative positive regions, which prefer block behavior through repulsion effect, adsorb polyiodides attraction respectively. Meanwhile, holds more Gibbs free energies consecutive radical reaction, much stronger adsorption species, manifesting fast conversion reaction kinetics, effective inhibition behavior. As expected, ZIBs based on delivers high capacity 153.6 mAh g −1 after 400 cycles at 0.1 A , reversible 152.8 500 0.5 (50 °C), durable cycling stability 12000 5 implying excellent fixation ability binder. This work guides design special iodine‐based electrodes facilitates practical application ZIBs.

Abstract The side reactions and dendritic growth largely impede the utilization of Zn anode in aqueous zinc ion batteries (AZIBs). Herein, a novel strong acidic electrolyte additive itaconic acid (IA) is introduced to achieve highly stable via dual functions. First, use trace amounts IA can provide steady low pH environment for electrolyte, which beneficial eliminate alkaline by‐products by neutralizing OH − that accumulated near anode. Second, an interfacial protective layer be situ formed cross‐linking reduction reaction between anode, helping inhibit continuous corrosion on promote formation uniform deposition. Consequently, achieves ultra‐long cycle‐life (5390 h at 1 mA cm −2 , mAh ) enhanced coulombic efficiency (99.86% upon 2100 cycles 5 −1 ). Besides, full cell assembled with sodium vanadate delivers high reversible capacity 179.6 g over 2000 2 A . This work offers new solution related insights design electrolytes additives toward AZIBs.

Compared with commonly used Zn foil anodes, powder (ZP) anodes offer superior versatility and processability. However, in aqueous electrolytes, dendrite growth side reactions, such as corrosion hydrogen evolution, become more severe ZP than those because of the rough surfaces high surface areas ZP, leading to poor reversibility limitations high-loading mass cathodes. In this study, a diisocyanate-polytetrahydrofuran-dihydrazide polymer (DDP) binder is developed, inspired by protein structures. The strong Zn2+ adsorption capability effectively regulates flux, while its unique hydrogen-bond arrays facilitate formation free-standing anode inhibit reactions. exhibits mechanical performance, providing electrodes excellent resistance various stresses, including tensile, nanoindentation, scratch, dynamic bending tests. symmetric cells achieve stable cycling at capacities 2 5 mAh cm-2. addition, DDP functions an iodine cathode, mitigating polyiodide shuttle effect. fabricated ZP/DDP||I2/DDP full demonstrate rate stability, even under conditions. This study presents novel approach for preparing cathodes, offering promising strategy large-scale applications.
