Harnessing organic electrolyte for non-corrosive and wide-temperature Na-Cl₂ battery.

ABSTRACT: Rechargeable sodium-chlorine (Na-Cl₂) batteries show great promise in grid energy storage applications due to their high electrochemical performance. However, the use of highly corrosive thionyl chloride (SOCl₂)-based electrolytes has severely hindered their real-world applications. Here we show a non-corrosive ester (methyl dichloroacetate) as a promising alternative to SOCl₂, which can form a non-corrosive electrolyte with aluminum chloride and sodium bis(fluorosulfonyl)imide for high-performance rechargeable Na-Cl₂ batteries. The resultant battery shows a reversible capacity of up to 1200 mAh g^-1 at a current density of 100 mA g^-1 calculated based on the mass of carbon with a discharge voltage of ~2.5 V, a wide temperatur
