Wet vs dry mechanical recycling process – an outlook for anodic active material recycling
Designing a sustainable production chain for Li-ion batteries (LIBs) represents a crucial step in the energy transition. The challenge of establishing electromobility as a green technology involves developing recycling processes that increase the recirculation of materials. Several industrial LIBs recycling processes reported in the literature combine mechanical, thermal and chemical treatments. The main processes currently […]
Hybrid modelling of Lithium-ion batteries: Proof of concept for application of Physics-informed Neural Network in Electrochemical Battery Modelling
Abstract Accurately forecasting lithium-ion batteries’ lifetime and degradation mechanisms are crucial for their optimization and management. An accurate state of health estimation is essential for ensuring safety and preventing latent failures. However, complex and dynamic cell parameters and wide variations in usage conditions make the state of health prediction challenging. Physics-based models need a tradeoff […]
Parameterisation of Electrical and Thermal Models at Module-Level for a Li-Ion Battery Digital Twin Simulation Platform
The monitoring and modelling of the Li-Ion Batteries behaviour is still a major technical challenge due to the non-linearities and coupled phenomena that determine their operation. Deployed Li-Ion Batteries (LIBs) are becoming increasingly large in scale and can consist of hundreds or thousands of individual cells. When these LIBs are in operation, there are some […]

Cost and performance analysis as a valuable tool for battery research: the case of the optimization of the low cut-off voltage of sodium-ion battery cells
The widespread use of lithium-ion batteries for renewable energy storage and electromobility is enabling our society to shift from a carbon-based economy to a more sustainable one. However, issues in the supply of the critical materials required for their production could harm the deployment of the necessary battery capacity. An alternative with a high technological […]
Balancing accuracy and complexity when selecting battery models to fit data
This talk raises the challenge of selecting battery models to fit the experimental data and provides a solution. We find that popular metrics to evaluate the model fit, such as root-mean-square error and Bayesian information criterion, can lead to incorrect model selection. We study the possible causes of this using the simplest battery model, an […]
Investigations on the improvement of the cycling behavior of lithium metal electrodes in combination with slurry-based sulfdic electrolyte layers
Sulfide solid electrolytes, such as Lithium Phosphorus Sulfide _-Li3PS4(LPS), show promising results in all solid-state battery research due to higher lithium-ion conductivity compared to solid ceramic electrolytes. Current research is trying to cope with different challenges with sulfidic electrolytes, among them: The use of a lithium (Li) metal anode to increase energy density. Inhomogeneous deposition […]
