The team led by Professor Helmut Ehrenberg, Head of the Institute for Applied Materials - Energy Storage Systems (IAM-ESS) at the Karlsruhe Institute of Technology (KIT), has researched a promising anode material: lithium lanthanum titanate with a perovskite crystal structure (LLTO).
As the study carried out in collaboration with scientists from Jilin University in Changchun, China, and other research institutions in China and Singapore has shown, LLTO anodes have a lower electrode potential compared to commercialized LTO anodes, which means that a higher cell voltage and a higher capacity can be achieved. Cell voltage and storage capacity ultimately determine the energy density of a battery. The study contributes to the work of the research platform for electrochemical storage CELEST (Center for Electrochemical Energy Storage Ulm & Karlsruhe), one of the largest battery research platforms worldwide, in which the POLiS Cluster of Excellence is also embedded.
