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

Leistungen

Workshop tutorials and report on workshops on the functionality and usage of the new work-flows and models, including feedback from consultations with the Industrial Exploitation Board. (Task 8.3)

Scaling strategies 3

Dissipative particle dynamics or Lattice Boltzmann approach coupled to kMC (Task 3.5)

Scaling strategies 1

Mean field model derived from kMC simulation Task 35

Optimized Techno-Economical model

Optimized mathematical model for the specific needs of organic redox flow batteries with different active materials Addition of further variable parameters and dependencies especially the integration of an optimized battery model Task 71

Upgraded kMC model

Upgrade of preexisting kMC code in Python programming language. Adaptation to organic based redox flow systems. (Task 3.1)

Scaling strategies 2

Hybrid model coupling mean field with kMC approach (Task 3.5)

Simplified model of the electrochemical double layer

Model of the electrochemical double layer without spatial resolution modelabbreviation DLM that is computationally less expensive than the kMC model of Task 31 Task 42

Use cases

Report on use cases, demonstrating the performance of new models and work-flows for dissemination and exploitation purposes (Task 8.3)

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)

kMC software deposit in GitHub

Release of kMC code in python programming language. This code will be parallelized (Task 3.1-3.8)

Numerical upscaling of the EDL model

One-dimensional RFB model (RFB-SCSM-1D) that is suitable for computer-based material screening, where details of cell components (membrane, porous electrodes) are described in interaction with the properties of new redox couples. (Task 4.3)

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)

Public dissemination

This report will cover all dissemination activities carried out during the project, in accordance with the dissemination plan (D8.2) (Task 8.2 and 8.6)
