Membrane for redox flow battery with Mn-ion electrolyte

The purpose of the project is to develop new membrane materials to increase the performance and lifetime of redox flow batteries (RFBs). RFBs have great potential for use in large-scale stationary energy storage in combination with solar or wind power.

In the project, a hybrid concept based on a hydrogen electrode and a flow electrode with manganese complexes will be studied and further developed.

By using manganese, the cell becomes more efficient, environmentally friendly and significantly economical than classic vanadium-based systems. Further savings can be made on the membranes.

In the project, potentially low-cost aromatic membranes with higher proton selectivity, lower metal uptake and water leakage will be synthesized and characterized at LU and electrochemically evaluated in a RFB at KTH. The work will be performed in close collaboration with Imperial College London. The development of competitive RFB for energy storage is essential for renewable electricity to fill a greater
