Numerical Simulation of Flow Batteries Using a Multi-scale Macroscopic-Mesoscopic Approach

The development of redox flow batteries presents challenges in terms of scale-up, optimization, improvements in electrolyte stability, and the development of new materials [1]. These challenges can be tackled using a combination of laboratory analysis and modelling, which lowers the financial costs and timescales. Modelling of the cells can provide insights into the coupled physico-chemical processes, including heat and mass transfer, the redox reactions, charge transfer and any phase changes, all of which are difficult to quantify experimentally. For design and optimization, an accurate model can be invaluable.
