Many renewable energy technologies, such as solar and wind, cannot provide energy on demand. This limits their growth in society when production and use timelines are mismatched. Hence, grid-scale energy storage is imperative to move towards a renewable energy future, and one of these enabling technologies is the redox flow battery (RFB). However, the state-of-art membrane material for leading RFBs, i.e. Nafion, accounts for 30 – 40% of the total battery cost, making it impossible to economically compete with fossil fuels. I will be working to develop a new membrane material for RFBs that is based on ceramic/ceramic-polymer hybrids produced using sol-gel processes. The primary motivation is that these new membranes are one-tenth the cost of Nafion, but can perform even better . They will have high ion conductivity and selectivity, will be chemically and thermally stable under harsh operating conditions and will be mechanically robust for manufacturing and device integration.
