Welcome @ Battery Technology Center
Generation, storage and use of electric energy on a sustainable and cost-efficient basis for stationary and mobile applications are among the biggest global challenges for the next decades. The research and development of innovative electrical energy storage systems is carried out in different institutes at KIT covering the entire value chain in a comprehensive, interdisciplinary approach. The objective is to develop industrially applicable, cost-efficient solutions for energy storage of the next generations.
Within the Battery Technology Center, the competencies of KIT along the value chain are pooled and an open technology platform for future electric energy storage systems is being set-up. The focus here is on the development and production of new materials and cells as well as the development of batteries and the integration to an overall system. Simultaneously, new manufacturing processes for the cost-efficient production of those batteries are being developed and demonstrated.

Federal Minister for Economic Affairs and Climate Action Visits KIT Pavilion. The researchers in the BiFlow project demonstrate new options for cost and space-efficient power and heat supply. The expansion of renewable energies requires adequate storage capacities. In BiFlow, a hybrid storage system is being developed that combines the advantages of lithium-ion batteries, such as high energy and power densities as well as high efficiency, with the advantages of vanadium flow batteries, i.e. their long service life and non-flammability. In addition, the electrolyte tanks of vanadium flow batteries serve as heat accumulators. This heat can be used for heating the water in the building, thus increasing the overall efficiency of the system.

In the latest edition of its electricity storage test, HTW Berlin evaluates 18 lithium-ion battery systems from 11 manufacturers. For the first time, the 2023 Power Storage Inspection together with Karlsruhe Institute of Technology (KIT) also analyzed so-called saltwater and high-temperature batteries.

In battery development, research and development are in a constant neck-and-neck race. The development of ever newer, more powerful cell systems is accompanied by reliable safety testing of lithium-ion cells. KIT researchers are working with other partners from industry and research in the ProLIB project to develop a more realistic testing method that should become established as a new standard in the future.
