Abstract
Methods to improve redox flow battery performance with improved CE, reduced electrolyte solution crossover, and simplified solution refreshing process have been developed. The methods include controlling the pre-charging degree and conditions to allow high quality metal plating (ductile and uniform), for example, Fe(O), on the negative electrode. Control of the pre-charging conditions can be combined with increasing the concentration of metal ions compared to existing systems, while maintaining the same concentration in both the negative and positive electrolytes, or increasing the concentration of metal ions in the negative electrolyte so that the negative electrolyte has a higher concentration of metal ions than the positive electrolyte.
