Aqueous aluminum-ion batteries (AAIBs) are considered as a promising alternative to lithium-ion due their large theoretical capacity, high safety, and low cost. However, the uneven deposition, hydrogen evolution reaction (HER), corrosion during cycling impede development of AAIBs, especially under harsh environment. Here, hydrated eutectic electrolyte (AATH40) composed Al(OTf)3, acetonitrile (AN), triethyl phosphate (TEP), H2O was designed improve electrochemical performance AAIBs in wide temperature range. The combination molecular dynamics simulations spectroscopy analysis reveals that AATH40 has less-water-solvated structure [Al(AN)2(TEP)(OTf)2(H2O)]3+, which effectively inhibits side reactions, decreases freezing point, extends window electrolyte.

In the relentless pursuit of technological advancement, world is steering toward groundbreaking progress, particularly in domain energy production and storage. storage domain, role Li-ion batteries (LIBs) indispensable, which leads to their propelling surge and, consequently, an upswing scrap generation. Considering environmental impact exorbitant value lithium heavy metals spent LIBs, a less hazardous more efficient recovery imperative. Herein, deep eutectic solvent (DES) was devised efficiently extract valuable from LIBs under optimized experimental conditions, notably without any additional reducing agents. We proposed two different choline chloride (ChCl)-based DESs, employing pyruvic acid (PA) glyoxilic (GLY) as hydrogen bond donors. Through vertical ionization potential (VIP) calculations, it observed that PA manifests lower VIP than GLY, indicating its propensity favored reductant for leaching cathode materials. Experimental findings further validated this assertion, demonstrating ChCl/PA (1:1) effectively extracts 99% both Co Li LIB materials at 80 °C within 5 h duration.
