Within the present project SIMBA we will develop highly porous carbon-rich silicon carbide according the procedure reported in our recently filed patent application (DE102016116732). This synthetic approach allows for tuning the pore morphology in line with the material composition. During the first charge, metallic sodium will be deposited in the pores of the SiC-based ceramic. In this way we will tackle the problem of the sodium dendritic growth since they will be encapsulated in the porosity of the support. We will also investigate the interfacial transport (anode – electrolyte, electrolyte-electrolyte and cathode – electrolyte) by means of electrochemical impedance spectroscopy (EIS) under varying external pressure. The EIS results will be complemented by investigations using 23Na solid state MAS NMR spectroscopy, electron microscopy (SEM/TEM) as well as by materials modelling.

Our expertise in materials synthesis and electrochemical characterization are essential for the realization of the overall target of the proposal, namely the development of novel electrode materials for application in Na-ion storage systems.

TUDa consists out of different department of which three work on the SIMBA project: TUDaa_RR, TUDa_GB and TUDa_KA.
