Philipp Schweigart
About
As part of the Norwegian Giga Battery Factories (NorGiBatF) project, my research takes an application-driven approach to electrochemical energy storage, with a special focus on high-power devices such as Lithium-ion capacitors (LICs). LICs combine the use of supercapacitor-type activated carbon electrodes with intercalation-based anodes (predominantly graphite) to achieve intermediate energy density while retaining favorable power density. My research explores new electrolyte formulations based on non-hydrolyzing salts, to enhance tolerance against water contamination to reduce the energy demand needed for the drying of cell components.
Moreover, the project investigates the replacement of conventionally used graphite anodes with silicon-graphite composite anodes for use in high-power Li-ion batteries and Li-ion capacitors. For this, the lithiation/delithiation behavior of silicon-graphite composite anodes is extensively studied via in-situ X-ray diffraction.
