Münster Electrochemical Energy Technology (MEET) of the University of Muenster is one of the foremost battery research centres in Germany and one of the leading drivers of top-level research internationally. With the aim of helping the urgently needed turnaround in the energy and transport sectors to succeed, the work done at MEET covers the optimisation of the market-dominating lithium-ion technology, the further development of other materials, and promising new approaches such as solid-state batteries. Specified on new and advanced materials, cell production and the recycling of battery cells, the team at MEET is making a decisive contribution to safeguarding energy supplies. Together with a strong collaborative network, the MEET scientists research into higher energy densities, longer lifecycles, maximum safety, improved sustainability and the lowest possible costs for energy storage.
