Speech Title: Synergistic effect of external fields on performance of non-aqueous redox flow batteries

Abstract: Compared with conventional aqueous electrolytes widely used in redox flow batteries (RFBs), non-aqueous Deep Eutectic Solvent (DES) has a wider electrochemical window, simple preparation, low vapor pressure and low cost, hence it has been used as electrolytes for RFBs. But the high viscosity of DES causes inferior transport property, resulting in lower cell performance. To address this issue, external fields are applied onto the DES-electrolyte RFBs. The changes on physical and electrochemical properties and impedance of DES electrolyte are studied by cyclic voltammetry and electrochemical impedance spectroscopy under the effect of temperature, magnetic field and supersonic field, respectively, and the underlying mechanisms are explored in detail. The fields-synergy is analyzed and the optimized multi-fields are applied to a DES electrolyte RFB, leading to a performance improvement up to 77%.
