ABSTRACT In the pursuit of advanced energy storage technologies that promote sustainable solutions, zinc‐ion batteries (ZIBs) have emerged as a promising alternative to lithium‐ion due their abundance, safety, and environmental advantages. However, failure mechanisms ZIBs under extreme temperatures are still not fully understood, presenting significant challenges development commercialization. Therefore, innovative strategies essential enhance adaptability temperature extremes. this review, we first explore thermodynamic kinetic aspects performance degradation temperatures, focusing on key factors such ion diffusion redox processes at electrode interfaces. We then comprehensively summarize discuss existing approaches for various electrolyte types, including aqueous, nonaqueous, solid state. Finally, highlight future prospects operating conditions. The insights presented in review expected accelerate advancement facilitate practical implementation large‐scale systems.

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 Electrolyte additives are commonly employed in aqueous zinc‐ion batteries (ZIBs) to suppress dendrite growth, corrosion, and hydrogen evolution. However, rational design principles systematic mechanistic studies for selecting suitable regulate reversible Zn plating/stripping chemistry worth in‐depth study. Using L‐ascorbic acid sodium (LAAS) as the representative, theoretical calculations combined with situ experimental analyses manifest that polyhydroxy‐sodium‐salts preferentially chemisorbed on surface construct H 2 O‐poor interfacial microenvironment, suppressing undesirable water‐related side reactions. Concurrently, ions provide an armor shielding layer electric field guide (002) deposition texture. Specifically, sodium‐salts replace O molecules coordinated shell of hydrated 2+ ions, improving electrochemical stability window (ESW) extend working voltage ZIBs. Therefore, Zn||Zn symmetric cell additive exhibits impressive cumulative capacity 7875 mAh cm −2 at high current density 30 mA . Even when discharge expands 1.8 V, Zn||V 5 full realizes a retention 98.26% over 500 cycles. This work quickens advanced ZIBs by green cheap electrolyte additive, which is expected herald innovative phase research high‐stability batteries.
