From 1988 to 1994, Jens Tübke studied chemistry with the specialization of technical and macromolecular chemistry at the Martin-Luther-University Halle Wittenberg. He wrote his diploma thesis on "Knoevenagel condensation of oligo (ethylene glycol) malone esters with formaldehyde" with the aim of synthesizing polar plasticizers for the production of suitable polymeric ionic conductors for lithium-ion batteries.
From 1994 to 1997, he worked with Prof. Sandner at the Martin-Luther-University Halle Wittenberg within the topic "Structure-Properties-Relationships of Polymeric Gel Electrolytes for Lithium-Ion Batteries" and finished his PhD in 1997.
From 1997-2000 followed an overseas stay at Kyoto University (Japan) in the working group Prof. Zempachi Ogumi and the Toyota Corp. with the aim of developing electrolyte and electrode materials for lithium-ion polymer batteries for hybrid and electric vehicles.
Since 2000, he has been working at Fraunhofer Institute for Chemical Technology ICT in the field of Applied Electrochemistry at the Fraunhofer-Gesellschaft, where he initially worked as principal investigator (PI) and headed the Battery-Group. His field of work includes polymer lithium batteries, development and synthesis of polymer (gel) electrolytes, graphite anode materials and various cathode intercalation materials for lithium-ion batteries. As a further work area battery characteristics and safety-relevant tests as well as abuse investigations and damage analyses were established.
Since 2008, Jens Tübke is Head of Department "Applied Electrochemistry" at Fraunhofer Institute for Chemical Technology and, as spokesman for the Fraunhofer "Batteries" Alliance, he coordinates the activities of the Fraunhofer-Gesellschaft in this field for national and international partners and customers.
In 2015 Jens Tübke was appointed to the Karlsruhe Institute of Technology with a professorship for "Materials and Processes for Electrochemical Storage". In this function, he is the Head of the "System Architecture" group at the Helmholtz Institute for Electrochemical Energy Storage in Ulm, and is dealing as principal investigator (PI) with the implementation of new battery materials in suitable cell formats and overall systems, while at the KIT at his Chair his working area is the process development for the production and processing of battery and fuel cell materials.
Since 2019, he has been in charge of planning and coordinating the "FoFeBat" project. In January 2020, he was appointed as the director of the Research Fab Battery Cells, which was part of Fraunhofer IPT at this time. Since January 2022, Fraunhofer FFB has been operating as an independent institution of the Fraunhofer-Gesellschaft. Since then, Jens Tübke has held the position of director at Fraunhofer FFB.
