Maximilian Fichtner

from Wikipedia, the free encyclopedia

Maximilian Fichtner (* 1961 in Heidelberg ) is a German chemist . Since 2013 he has been Professor of Solid State Chemistry at Ulm University and is currently Deputy Director of the Helmholtz Institute Ulm for Electrochemical Energy Storage (HIU). Fichtner is Scientific Director of CELEST (Center for Electrochemical Energy Storage Ulm-Karlsruhe) and spokesman for the POLiS Cluster of Excellence .

Career

Fichtner studied food chemistry and chemistry at the University of Karlsruhe [meanwhile Karlsruhe Institute of Technology (KIT)], where he graduated with a diploma in chemistry. In 1992 he was awarded a Dr. rer. nat in chemistry / surface sciences and received the Hermann-Billing Prize for his work , which is awarded annually by the student union Corps Friso-Cheruskia Karlsruhe and the KIT.

After completing his doctorate, he received funding as a young scientist at the former nuclear research center in Karlsruhe (KfK), where he further developed his method for investigating organic materials. In 1994 he accepted the position of executive officer at the Forschungszentrum Karlsruhe (FZK) in the field of "Basic Research and New Technologies". In 1997 he left this speaker position to start a new activity in the field of “chemical and thermal microprocess engineering”. The main focus of the work was heterogeneous catalysis in microchannels with the subjects of “fuel process technology” ( methanol steam reforming, partial oxidation of methane ) and the synthesis of fine chemicals. In 2001 the group was integrated into the newly founded “Institute for Micro Process Engineering”.

In 2000, Fichtner took over the development and management of another group at the newly founded “Institute for Nanotechnology” (INT) with the topic “Nanoscale materials for energy storage”.

In 2012 he was appointed professor of solid-state chemistry from Ulm University , which he accepted in 2013. This was connected with the management of the "Materials-I" department at the newly founded Helmholtz Institute Ulm (HIU). He has been the managing director of the institute since 2015.

Fichtner was and is also the coordinator of several EU projects and joint projects of the federal ministries for education and research and for economy and energy . He organizes various symposia and also chairs symposia.

In 2018 he was elected scientific director of the research platform "CELEST" (Center for Electrochemical Energy Storage Ulm & Karlsruhe). He is also the coordinator of a cluster of excellence within the framework of the federal and state excellence strategy. The POLiS Cluster of Excellence, successfully acquired by Ulm University and KIT, is the only Cluster of Excellence on the subject of batteries.

research

Fichtner gained experience in various fields such as theoretical chemistry , instrumental analysis , higher administration, chemical process engineering, heterogeneous catalysis , hydrogen storage , electrochemistry and battery research .

The results of his pioneering work are the first measurements of salts with secondary neutral particle mass spectrometry (SNMS), the development of a depth-resolved compound analysis with secondary ion mass spectrometry (SIMS), with which salts sensitive to ion bombardment could be analyzed for the first time , or a microstructured reactor in where a stoichiometric oxyhydrogen gas mixture was catalytically burned and the resulting heat of reaction could be safely transferred to a heat transfer oil.

In the development of new materials for hydrogen storage , two new complex hydrides , magnesium alanate and magnesium borohydride , were synthesized and tested in their pure form. With a Ti13 cluster as a catalyst, previously unattainable loading and unloading speeds were measured with the storage material sodium alanate , simultaneously with the Bogdanovic working group at the MPI Mülheim. Further work in this area focused on the investigation of nanoscale effects in energy materials. Based on work on the nanostructuring of different types of hydrides since the late 1990s in research work by numerous worldwide working groups, not only the change in the kinetic, but also the change in the thermodynamic properties of nanoscale magnesium hydride and complex hydrides was experimentally demonstrated in his group for the first time.

In battery research, new synthesis methods were developed with which conversion electrodes achieved a stable cycle behavior for the first time. New battery types based on anionic charge carriers such as fluoride and chloride ions were presented and a new electrolyte for magnesium batteries was developed. This has a voltage window of 3.9 V and is suitable for reversible magnesium-sulfur batteries. In addition, a new class of cathode materials for Li-ion batteries was presented that achieve a previously unattainable packing density for Li-ions in the solid state , the so-called "Li Rich FCC Materials".
