Abstract: A method for selectively recovering a rare earth element (REE) from an alloy includes applying a potential of from -3.5 V to 0 V to an electrochemical cell comprising a anode, a cathode, and an electrolyte, wherein (i) the anode comprises an alloy comprising a REE, (ii) the cathode comprises a noble metal, and (iii) the electrolyte comprises an alkali metal or alkaline earth metal salt and a nonaqueous solvent. Under the applied potential, at least some of the REE is oxidatively dissolved from the anode and is electrodeposited onto the cathode to form an REE deposit.

Abstract: Disclosed herein is an aluminum-ether-based composition that can serve a dual role as either an electrolyte for use in batteries and/or as an electroplating bath for ambient temperature aluminum deposition. The aluminum-ether-based composition facilitates aluminum ion transport between anodes and cathodes and thus can be used to replace expensive and hydroscopic ionic liquid electrolytes typically used for aluminum-based batteries. The aluminum-ether-based composition also can be used for causing aluminum deposition at ambient temperature and thus can be used to form aluminum-containing coatings with less energy consumption.

Abstract: Aqueous anolytes for redox flow batteries are disclosed. The anolytes include a fluorenone-fluorenol derivative, an additive comprising an organic compound including one or more proton acceptor groups, an alkali metal hydroxide, and water. The additive functions as a homogeneous organocatalyst and may increase the current density of an aqueous redox flow battery including the anolyte.
