Project abstract
Two trends in Li-ion research are currently developing at a rapid speed: (1) using finite element methods (FEM) to estimate lifetime, ageing mechanisms, etc., and (2) using machine-learning (ML)/artificial intelligence (AI) tools for analyzing large data sets of battery test data, and thereby creating models for battery ageing depending on use conditions. This project regards the combination of these two approaches, to assist training and validating the AI, and rendering the ML models better transparent in terms of physical description. Thereby, they can be used for improved battery design. Battery FEM models will thus be employed in this project to generate a much larger matrix of simulated battery ageing data, which the ML model will be validated against. Moreover, the FEM data sets generated will aid in determining which ageing mechanism that is dominating under what battery operating condition, and why.
