A Rechargeable Aqueous Aluminum-Sulfur Battery through Acid Activation in Water-in-Salt Electrolyte

Abstract

We demonstrate the first rechargeable aqueous Al-S battery based on water-in-salt electrolyte with the configuration of Al║Al(OTF)3+LiTFSI+HCl║S/C. The superconcentrated LiTFSI traps water molecules to inhibit the hydrolysis of aluminum polysulfides in cathode, and the HCl additive provides mild acidic environment to enable repeatable oxidation-reduction reaction in the anode.
