Batteries are playing a fundamental role in the transition to a sustainable future. On the one hand, they can be used for storing surplus power produced by renewable energy sources, on the other hand, they are currently the most promising alternative to fossil fuels for transportation.

However, compared with fossil fuels, batteries can store much less energy per volume or weight and their price is relatively high. To meet the requirements of the transport sector, significant improvements in terms of energy and power density, durability, price and safety are needed.

At DTU Energy, we are working on discovering new battery types with improved energy density, power density, durability and stability as well as on developing new tools to accelerate their discovery. Our main activities are centred on atomistic and multiscale in-silico materials design, accelerated by advanced machine learning models, and combined with the synthesis, characterization and testing of the most promising new materials which will close the loop of the materials discovery.

In the department, we are not only working on the development of novel materials for existing battery technologies, e.g. new cathodes and solid electrolytes for lithium-ion (and similar metal-ion) batteries, but also on emerging technologies such as next-generation metal-air and metal-sulphur batteries which have a significantly higher energy density and potential lower cost.

To achieve our ambition goals, we work in close collaboration with national and international research institutions and industrial partners and, moreover, we are involved in multiple large national and European initiatives.
