![]() Besides KIT and UUlm, also ZSW Ulm and the Justus-Liebig University in Giessen were partners in the consortium. The idea was selected and eventually became one of the first stage proposals submitted in February 2017. In the following years, HIU took an active role in driving and strengthening the collaboration between the partners and attracted researchers from all over the world who wanted to work at the forefront of electrochemical energy storage.īuilding on the successful work and collaboration within the HIU, a first suggestion for a joint proposal was sent to the boards of KIT and Ulm University in spring 2016, with the aim to participate in the new German Excellence Strategy and apply for a Cluster of Excellence on “Energy Storage Beyond Lithium”. The institute is carried by KIT as legal entity, with Ulm University as partner and ZSW Ulm and DLR as associate partners. ![]() The proposal was evaluated by an international review commission and granted in November 2010.Īlready in January 2011, the Helmholtz-Institute Ulm for Electrochemical Energy Storage (HIU) was founded. In September 2010, a proposal was submitted to the German Helmholtz Association of Research Centers, with the aim to establish a new institute. Motivated by these circumstances, a group of scientists from Ulm and Karlsruhe led by Horst Hahn from the Institute of Nanotechnology at KIT met at the scenic Reisensburg in spring 2010, to discuss the structure and content of a new and joint effort in the field of Electrochemical Energy Storage. More than 20 years later, Germany began aiming at playing a major international role in research and development of modern batteries, and electrochemistry – a topic that had been dormant for a while – gained tremendous attention again. The collaboration of Ulm University and Karlsruhe University dates back to the 1980s, where several research groups collaborated on various aspects of electrochemistry. Synergies of Karlsruhe and Ulm Battery Research POLiS is funded with 47 million euros over seven years. With this concept, the Karlsruhe Institute of Technology (KIT), the Ulm University, the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) and the University of Giessen have asserted themselves in the Excellence Strategy of the Federal Government and the Länder - as the only German Cluster of Excellence for battery research. These so-called post-lithium batteries have the potential to store more energy, be safer, and offer a more cost-effective, long-term option for mass applications such as stationary and mobile electrochemical storage. We have identified sustainable alternatives that no longer rely on lithium and other critical materials: We are researching batteries based on sodium, magnesium, calcium, aluminium and chloride ions. The Cluster of Excellence POLiS develops the necessary new battery materials and technology concepts for efficient and sustainable storage of electrical energy. The European Commission fears supply bottlenecks due to scarcity of resources and the uncertain political situation of some countries with large reserves. ![]() The extraction of components such as cobalt, graphite and lithium involves political, ecological and economic risks. However, the battery chemicals used are not sustainable in the medium and long term. ![]() Lithium-ion batteries are currently the best battery option as they offer high voltages and thus high energy densities. Lithium-ion batteries have not only enabled the consumer electronics revolution, they are also about to enable electric-driven transportation and will substantially contribute to the energy transition (“Energiewende”), providing intermediate storage of electric energy for efficient use of intermittent renewables such as solar or wind in decentralized facilities. Batteries are one of the key technologies of the next decades. ![]()
