Grid scale batteries need to be inexpensive to manufacture, safe to operate, and non-toxic in composition. Zinc aqueous (alkaline) batteries hold much promise, but good cycle life and utilization of the zinc has proven difficult partly because zinc is susceptible to H2 gas evolution in KOH. Water-insalt electrolyte (WiSE) can address this shortcoming by lowering the activity of free water molecules in solution, thus reducing H2 gas evolution. In this work, we show the relevant fundamental physicochemical properties of an acetate-based WiSE to establish the practicality and performance of this class of WiSE for battery application. Research and understanding of acetate WiSE is in a nascent state, presently.
