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.
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.

This dependence is of critical importance during battery operation; since the SOC of the solution for each half-cell electrolyte could be changed, the vanadium concentrations may differ accordingly because of the ionic diffusion processes across the membrane and thus the solution conductivities vary.
