Renewable energy sources such as wind and solar give rise to a problem, since they’re not always available, they require grid-scale storage solutions. The field of flow battery technologies is a suggested solution for this problem. This is done by electrochemically charging certain chemicals and discharging them later, exchanging energy from electrical to chemical and then to electrical again. In order to widely distribute a solution for energy storage, we need to reduce its cost. A way to do so in flow batteries is by removing the membrane, one of the most common and most expensive components in a flow battery.
In this seminar, we explore a Membrane less redox flow battery with an elongated geometry and zinc-bromine chemistry. The low cost of the bromine makes it attractive. This seminar specifically explores single-flow multiphase flow batteries based on zinc-bromine chemistry with the addition of a polybromide phase in order to remove the expensive membrane that is usually found in this type of battery, which serves to lessen the corrosion on the anode, one of the battery’s electrodes.
