Abstract Despite the advantages of low cost, safety, and environmental friendliness, aqueous zinc‐ion batteries (AZIBs) encounter challenges such as zinc dendrite formation, severe side reactions, electrolyte instability. Many effective additives exhibit limited solubility in water, thus reducing their practical application potential. In this study, a dissolution‐promoting strategy is proposed by introducing citric acid (CA) to enhance dissolution aspartame (APM), resulting sulfate electrolyte. Simulations experiments indicate that CA regulates both solvation structure Zn 2+ pH electrolyte, while APM preferentially integrates into electric double layer form solid interphase with CA, thereby suppressing hydrogen evolution reactions. Consequently, zinc‐zinc symmetric cell exhibits an extended lifespan over 4,500 h at 1.0 mA cm −2 /1.0 mAh . As result, AZIBs commercial foil MnO 2 enhanced rate capability improved capacity retention (75.6%) after 2,000 cycles. This study presents novel for stabilizing anodes offers comprehensive framework addressing fundamental AZIBs, advancing next‐generation energy storage systems.

ABSTRACT Due to the strong affinity between solvent and Li + , desolvation process of at interface as a rate‐controlling step slows down, which greatly reduces low‐temperature electrochemical performance lithium‐ion batteries (LIBs) thus limits its wide application in energy storage. Herein, improve tolerance, localized high‐concentration electrolyte based on weak solvation (Wb‐LHCE) has been designed by adding diluent hexafluorobenzene (FB) solvating tetrahydrofuran (THF). Combining theoretical calculations with characterization tests, it is found that addition FB, dipole–dipole interaction causes FB compete for THF. This competition move away from weakening binding THF, whereas anions are transported into shell forming an anion‐rich structure. In accelerating process, this unique structure optimizes composition CEI film, making thin, dense, homogeneous, rich inorganic components, improving interfacial stability battery. As result, assembled LiFePO 4 /Li half‐cell shows excellent performances low temperature. That is, can maintain high discharge specific capacity 124.2 mAh g −1 after 100 cycles rate 0.2C −20°C. provides attractive avenue design advanced electrolytes improvement battery tolerance harsh conditions.
