Název v původním jazyce

A complex four-point method for the evaluation of ohmic and faradaic losses within a redox flow battery single-cell

Popis výsledku v původním jazyce

We propose a complex 4-point method for characterization of flow batteries. The distribution of ohmic and faradaic losses within a single-cell is evaluated from electrochemical impedance spectra and load curves of positive and negative half-cells measured with platinum wire pseudo-reference electrodes positioned in respective electrode compartment. The developed method can be used e.g., for the component screening and in-situ durability studies on single-cell scale. The method was validated on a vanadium redox flow battery single-cell; however, it can be analogically employed for various chemistries of flow battery. • Complex 4-point method for characterization of flow battery single-cell was developed. • Method is based on electrochemical impedance spectra and load curve measurements. • Direct evaluation of ohmic and faradaic losses distribution within battery single-cell by the method. © 2019 The Author(s)
