The aim of the project is to develop an innovative aqueous Zinc/Manganate-Permanganate hybrid Redox-Flow system with an energy density up to 2 times higher than Vanadium based ones (VRFB). This is possible due to a particularly high discharge voltage (1.80V; 40% higher than VRFBs), an alkaline catholyte with very high energy density (theoretical catholyte > 160 Wh/L) and a massive, porous zinc electrode. The energy density of the targeted system is around 40Wh/L. Particular attention will be paid to the development of very stable selective polymer membranes to reduce cross-over. Finally, two types of batteries, each with a capacity of 10 Ah, will be produced as a proof of concept and to evaluate the energy, power and life span of this system. The REDZIM battery, designed for the storage of renewable energies, is particularly respectful of environmental constraints, it has an increased safety and is non-toxic.
