Modelling for the search for new active materials for redox flow batteries

Deliverables

Database with DFT results for data-driven models

For a large set of redox-active molecules, the electronic structure parameters needed to train and validate machine-leraning models will be calculated and stored in an accessible database format. The precise content of the database will depend on the specific requirements of the model, but will include redox potentials, solvation free energies, and any potential desriptors derived from electronic structure calculations. (Task 2.2)

1D single cell performance model

One-dimensional continuum-scale RFB model (RFB-OS-1D) to simulate the driving potentials and fluxes of mass and charge in the through-plane direction of the cell assembly. A manuscript including the model description is submitted to a scientific journal. The source code of the model is included in the article submission. (Task 4.1)

Database with calculated parameters for kMC simulations

For selected redox-active molecules, a database with parameters needed for performing kinetic Monte Carlo simulations will be generated. It will include reaction rates calculated from first principles for e.g. chemical and electrochemical degradation reactions, or heteregenous electron transfer reactions. (Task 2.3)
