Project

Membrane and electrolyte development for redox flow batteries

One of the largest challenges in the worldwide energy transformation to renewable energy  is  the  fluctuating  energy  output  that  has  to  be  balanced  by  large-scale energy  storage.  Redox  flow  batteries  (RFBs)  are  one  of  the  more  promising approaches for such large-scale energy grids.However, there are some challenges for RFBs, including high cost and low power density. In this project, metal-free (organic) redox pairs and/or porous non-fluorinated membranes will be developed to achieve low cost. While high energy densities will be reached by increasing the solubility of redox pairs in supporting electrolytes or by developing redox pairs with high cell potentials. Finally,the battery will be scaled up with these redox pairs and membranes to achieve designed power, and it will be connected with a small commercial solar power plant.
