  • Synthesis and characterization of cathode materials for multivalent ion batteries
  • Cell assembly and characterization of zinc and sodium ion batteries


PhD Thesis:

Limited and unsure availability of lithium widely used in lithium ion batteries lead to a high interest in the research field of multivalent ion batteries. Multivalent ions such as zinc, aluminum and magnesium score with their high availability, low costs and non-toxic behavior. Due to higher oxidation states of these ions there is a higher energy turnover per mol of ions which are transferred.

My aim is to synthesize different cathode materials such as manganese dioxides, their characterization and assembly to battery cells.
