Research

Environmentally friendly energy storage solutions are very important to combat anthropological climate change. Aqueous organic redox flow batteries is a promising candidate where redox-active molecules are stored in tanks and are pumped through electrochemical cell when charging or discharging. 

My research is related to optimizing the energy efficiency, stability and energy density of these batteries. I am trying how to do this in three different ways: Firstly, by proper design of the redox-active molecules and supporting electrolytes. Secondly, by using solid boosters where pellets of solid material is added to the electrolyte reservoirs of the battery. Lastly, by adding organic molecules (so called hydrotropes) to the electrolyte solution, and studying the effect on solubility of the redox-active molecule and battery performance.
