Long-standing experience and always on the cutting edge: The InES contributes substantial progress in the four research areas Batteries, Pharma-Process Systems Engineering, Energy Systems and Electrochemical Process Engineering. The scientific work at the InES is based on the development of process systems engineering concepts and their applications, where particular attention is paid to the analysis and optimisation of (electro-) chemical processes using multi-scale simulations. For this purpose, our modern laboratories supply the required data and complete our model-based research by extensive validation experiments.
