Abstract Aqueous Zn‐ion batteries (ZIBs) are a promising energy storage technology due to their intrinsic safety, eco‐friendliness, and cost‐effectiveness. However, aqueous electrolytes generally induce parasitic interfacial reactions (e.g., dendrite growth passivation) that degrade the Zn metal anode, shortening ZIBs lifespan. This study develops novel hydrated deep eutectic electrolyte (DEE), containing sulfolane (SL) Zn(ClO 4 ) 2 ·6H O, prevent water‐induced deterioration. The strong...
Abstract Solid‐state batteries (SSBs) are an emerging technology for safe and high‐energy‐density electrochemical energy storage. Unfortunately, SSBs suffer from inadequate ionic conductivity sluggish interfacial transport at subzero temperatures, which limit their widespread application. Herein, a flexible, stable, highly conductive quasi‐solid polymer electrolyte (QSPE) is developed that allows low‐temperature (LT) operation. The in situ polymerized QSPE has integrated battery structure,...
Abstract Rechargeable batteries with Li‐metal anodes and Ni‐rich LiNi x Mn y Co z O 2 ( + = 1, NMC) cathodes promise high‐energy‐density storage solutions. However, commercial carbonate‐based electrolytes (CBEs) induce deteriorative interfacial reactions to both NMC, leading Li dendrite formation NMC degradation. Moreover, CBEs are thermally unstable flammable, demonstrating severe safety risks. In this study, an ultrathin non‐flammable dual‐salt polymer electrolyte (DSPE) is proposed via...

Abstract Aqueous Zn‐ion batteries are promising and safe energy storage technologies. However, current aqueous electrolyte battery technology is hindered by undesirable reactions between the electrodes, which can lead to Zn dendrite growth, gas evolution, cathode degradation.
