Abstract Aqueous zinc ion batteries have shown great potential for large‐scale energy storage systems and attracted widespread market interest. However, side reactions such as passivation of anode hinder its further development towards practical applications. In this paper, sodium dodecylbenzene sulphonate (SDBS) was used an aqueous electrolyte additive to improve the cycling performance. The experimental results show that SDBS can form a stable protective film on electrode surface, inhibit formation growth dendrites, reduce electrolyte, thus improving electrochemical performance battery. application in Na 3 V 2 (PO 4 ) /Zn (NVP/Zn) full significantly improves Coulombic efficiency batteries, inhibits occurrence reactions, slows down decay reversible specific capacity. NVP/Zn cell with addition achieved 81% capacity retention after 100 cycles at 0.5C magnification, polarization reduced. This work provides simple feasible method increase diffusion rate Zn 2+ .

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.

Abstract Hydrogel electrolytes have been widely explored in aqueous zinc‐iodine batteries (AZIBs), light of their intrinsic strong water‐retention capability and superior flexibility hydrogel network. However, hydrogel‐based AZIBs are still facing challenges due to the inferior ionic conductivity, dendrite formation, corresponding fatigue‐induced damage. Herein, a electrolyte is designed engineered with preferentially aligned porous structures, where Zn 2+ can promptly transport along pores. fabricated from exhibited distinct cycling stability over 1,000 h (500 cycles) at 0.5 mA cm −2 .

Despite showing low cost, inherent safety, and high suitability, the rechargeable Zn–I2 aqueous batteries are still seriously suffering from self-discharge energy density issues stemming I2 dissolution, polyiodide shuttling, mass loading. Herein, we develop a novel polyquaternium-10 (P10, cationic cellulose)-based binding system to simultaneously circumvent these issues. The water-borne P10 binder can suppress dissolution shuttling by not only adsorbing polyiodides via its quaternary ammonium groups oxygen heteroatoms but also eliminating use of toxic, expensive, I2-dissolving organic solvents (e.g., N-methylpyrrolidone, NMP), enabling facile green cathode-fabricating process. More importantly, is conducive preparation thick cathode coatings with loadings, thanks elasticity mechanical toughness after swelling electrolyte. As result, prepared demonstrate much better anti-self-discharge performance than those conventional PVDF binders (capacity retention: 84 vs 63% 200 h open-circuit storage). Even at an ultrahigh loading 14.5 mg cm–2, deliver significant specific capacity (216 mAh g–1) cyclability (96.8% remained 385 cycles). This should be highly compatible other performance-improving strategies, providing yet affordable approach for construction high-performance batteries.
