Tasks
Development and implementation of a model to describe:
Thermally induced gas release (e.g., due to electrolyte, binder, or SEI decomposition)Accumulation of gas pressure inside the cellActivation of the safety valve (venting)Optionally, initial steps towards flow simulation of vent gas release (CFD) can also be taken.
Research tasks:
Literature research on gas formation reactions and venting in LIBsDevelopment of a coupled thermal-chemical model (e.g., in Python, COMSOL, MATLAB)Implementation of temperature- and time-dependent gas generation rates using Arrhenius kineticsModeling of pressure accumulation within a cellSimulation-based prediction of venting activation (depending on opening pressure and gas volume)Optional: CFD-based investigation of gas release or flame formation (OpenFOAM or FDS)
