The lithium-ion batteries currently available for e-mobility are being optimized primarily to increase power density. However, the requirements are different for batteries for stationary energy storage in rural, decentralized electrification. They should be inexpensive, consist of readily available materials, be easy to recycle, have a robust cell chemistry and not be complex in its overall operation. In order to combine these contrasts, the “Electrochemical Energy Systems” junior research group at Hahn-Schickard and the Department of Microsystems Engineering (IMTEK) at the University of Freiburg is working on a new storage concept. The researchers led by Dr. Matthias Breitwieser and Dr. Severin Vierrath are combining this concept with a scalable and intelligent battery system. The “Plug-In” project has now been included in the “World Storage” program.
With this program, the Federal Ministry of Education and Research (BMBF) wants to support new ideas that have the potential for leapfrogging innovations and accelerate their implementation. The twelve-month concept phase of the Baden-Württemberg consortium will start on June 1, 2020, after which the BMBF will provide up to two of the currently approved “World Storage” projects with up to five million euros over a maximum period of three years in order to transfer the ideas to practical applications.
