Streb, Carsten - Ulm University - Molecular Metal Oxide Composites

研究领域

Molecular metal oxides – so-called polyoxometalates (POMs) are promising materials for the use in battery electrodes. POM synthesis by so-called self-assembly gives access to complex molecular aggregates based on simple, often commercial precursors. Chemical modification of the POMs, which are typically based on vanadium-, molybdenum- or tungsten-oxide by incorporation of a wide range of reactive metals enables the performance tuning and battery device optimization. In addition, POM integration into conductive substrates such as nanostructured carbon, metal electrodes or conductive polymers is possible and gives access to molecularly linked POM composites. The topics of the research group are therefore focused on new materials syntheses, electrochemical performance characterization using theory and experiment, as well as developing innovative composite design routes using bottom-up self-assembly reactions including microwave and ultrasonication routes. In-depth analyses – ideally under operating conditions – form the basis for novel, nanostructured composites as next generation battery electrodes for Lithium and Post-Lithium systems.
