A fast screening method: for evaluating water loss in flooded lead acid batteries was set up and the Tafel parameters for both linear sweep voltammetry and gas analysis tests, determined at 60 °C for water consumption, correlated well with the concentration of Te contaminant, to be considered responsible for the increased water consumption.
An ideal SEI layer would directly prevent access of the aqueous electrolyte to the electrode surface while allowing the charge-carrying cations through. However, a functioning SEI layer is lacking in aqueous batteries with dilute electrolytes, owing to both the narrow ESW of water and the high solubilities of SEI species.
In the case of aqueous Zn-ion batteries, since metallic zinc has an electrode potential much lower than that of the standard hydrogen electrode (−0.76 V), HER is thermodynamically favorable, posing a fundamental change to the successful implementation of the new chemistry.
