Memristive Information Storage and Logics group: "How
does Moisture affect the Physical Property of Memristance for
Anionic-Electronic Resistive Switching Memories?" and also the first publication of the Solar-to-Fuel Conversion Reactor Materials team: "Perovskite La0.6Sr0.4Cr1-xCoxO3-δ
Solid Solutions for Solar-Thermochemical Fuel Production: Strategies to Lower
the Operation Temperature".
The Electrochemichal Materials Group makes, designs and investigates materials for novel solid state electrochemical information storage and logic devices, and energy storage and converter units. Here, researching and engineering charge and mass transport at interfaces and within the bulk of the materials are the key. Prominent exampels of the research are the understanding of material kinetics to device performance for memristive information storage/logic devices incl. new structure-ionic transport tuning guidelines for novel prototypes.
All solid state Li batteries co-operating on waste heat for stationary energy grid storage, miniaturized all solid state thin film batteries for on-chip power supply in portable electronics and also as model systems to fundamentally understand the role of material design and charge transfer/capacitances at bulk and interface are in focus in processing, material making and battery electrochemistry and design. New design rules for solar-to-fuel conversion materials may define next generations efficiency
to store grid independent solar energy through solar-driven thermochemical water
and CO2 splitting in sizable-tanks. We focus on new perovskite materials, thermodynamics and kinetics to increase solar-to-fuel efficiencies for reactors.
Micro-solid oxide fuel cells are fascinating solid state devices to understand electrochemo-mechanics for energy conversion membranes and are alternative grid-independent energy supply convertors due to their high specific and volumetric energies for portable electronics to classic batteries.
