Abstract The application of aqueous zinc‐ion batteries in large‐scale energy storage systems is significantly limited by the hydrogen evolution reaction (HER). Although conventional pH‐adjusting additives can reduce overpotential HER, it imperative to simultaneously modulate composition solid electrolyte interphase (SEI) and electrical double layer (EDL) structure enhance utilization zinc metal. This research develops a multifunctional pH‐controlling additive, bis(2‐hydroxyethyl)amino‐tris(hydroxymethyl)methane (BT). First, addition BT increases pH 5.9, which within its effective buffer zone, reduces HER potential −1.107 V versus Ag/AgCl. Second, inhibitory effect on be further enhanced preferential adsorption molecules containing multiple hydroxyl functional groups anode, leading reduction number active water EDL. Third, participate solvation accomplish reduction, promotes uniform deposition Zn 2+ ions forming nitrogen‐containing SEI. Ultimately, symmetric battery accomplishes 2700 stable cycles BT‐3 electrolyte. More crucially, corresponding Zn//MnO 2 full (1 A g −1 ) able release specific capacity 117.2 mA h after 600 cycles.

Abstract Anode‐free sodium batteries (AFSBs) hold great promise for high‐density energy storage. However, high‐voltage AFSBs, especially those can stably cycle at a wide temperature range are challenging due to the poor electrolyte compatibility toward both cathode and anode. Herein, AFSBs with cycling ability in (−20–60 °C) realized first time via sole‐solvent high‐entropy based on diethylene glycol dibutyl ether solvent (D2) NaPF 6 salt. The unique solvent‐ions effect of strong anion interaction weak cation solvation enables entropy‐driven salt disassociation high‐concentration contact ion pairs, thus simultaneously forming stable anion‐derived electrode–electrolyte interphases Moreover, liquid D2 further extends extremes battery. Consequently, ampere‐hour (Ah)‐level anode‐free pouch cells cyclability −20–60 °C realized. Impressively, cell achieves leadingly high cell‐level density 209 Wh kg −1 capacity retention 83.1% after 100 cycles 25 °C. This work provides inspirations designing advanced electrolytes practical AFSBs.
