The evolution of the global energy scenario and growing energy consumption drive the demand for large-scale energy storage. In this context, Redox Flow Batteries (RFB) represents an alternative solution to Lithium-Ion Batteries (LIB) due to the absence of safety issues related to fire and explosion hazard and the more flexible design due to decoupled energy and power. The development of innovative electrolytes from abundant, cheap, and non-critical materials contributes to reducing the cost and increase the sustainability of the RFB technology. Different materials and solutions are being investigated for novel flow batteries such as complexing agents for stabilizing inorganic species, solid-boosters to improve storage capacity and flowable slurry electrodes.

This project aims to evaluate the potential of these solutions from material to system level. After a system level and sustainability assessment, the mechanisms that trigger and favour degradation will be studied using also in-situ techniques. Work will focus both on material and cell engineering issues to ensure that developments will be scalable and could benefit the European industry.
