Guidelines for designing highly concentrated electrolytes for low temperature applications.

Guidelines for designing highly concentrated electrolytes for low temperature applications. Chem Commun (Camb). 2020 Jul 27;: Authors: Ah-Lung G, Flamme B, Ghamouss F, Maréchal M, Jacquemin J Abstract The redefinition of the commonly named "water-in-salt" clarifies the operating temperatures of the state-of-the-art LiTFSI-based aqueous solutions. An in-depth study shows its mismatch for low temperature applications. In contrast, the recommended strategy is to design an electrolyte with an invariant composition, as exemplified by the eutectic water/LiNO3 that is able to electrochemically cycle down to -23 °C.
