A Strategy for Enhancement of Power Density in Fe-Based Solvation Difference Flow Battery by Using Solvent that Generates a Large Potential Shift of Ferrocyanide/Ferricyanide.

ABSTRACT: Effective utilization of thermal energy is attracting attention for the realization of a carbon-neutral society. To convert thermal energy into electrical energy, we recently proposed a solvation difference flow battery (SDFB), a new type of thermally regenerative flow battery, whose electrolyte can be regenerated using thermal energy. The power density of SDFB, however, is relatively low compared with that of the other thermally regenerative flow batteries, and the strategy of the electrolyte design for SDFB to improve the power density has not been clear so far. In this study, we focused on the redox potential of ferrocyanide/ferricyanide in six different solvents (water, ethanol, acetone, 1-butanol, acetonitrile, and dimethyl sulfoxide (DMSO)), where the largest potential difference was
