In this paper, we present a physics-based electrochemical model of a vanadium redox flow battery that allows temperature-related corrections to be incorporated at a fundamental level, thereby extending its prediction capability to low temperatures.
Vanadium redox flow batteries (VRFBs) are one example of redox flow batteries that have reached the stage of commercial deployment for grid-scale application. Extensive research has been carried out on several variants of VRFB over the past few decades.
1. Increasing the ambient temperature around the vanadium redox flow battery (VRFB) has been shown to reduce the charging voltage and increase the discharging voltage, thereby enhancing the charge and discharge capacity. With the temperature increase, the Coulombic efficiency decreases, while the voltage efficiency improves.
Abstract: The performance of vanadium flow batteries (VRFB) can be severely reduced when operating at low temperatures due to changing electrolyte properties. In this work, we develop a non-isothermal model of VRFB dynamics that takes into account changes in electrolyte viscosity depending on temperature.
