Redox Flow Battery Having Metal-Ligand Complex
- Los Alamos National Lab. (LANL), Los Alamos, NM (United States)
Researchers at Los Alamos National Laboratory have developed new non-aqueous electrolyte materials for redox flow batteries (RFB). These batteries are a viable technology for scalable energy storage beyond lithium ion batteries. Cost is currently limiting deployment, with poor energy density being the primary culprit. One way to improve energy density is by increasing the cell potential beyond the current limit in aqueous media. The higher cell potential and additional electrons stored per molecule will increase the energy density of the RFB medium, overcoming a critical limitation to the current RFBs. Like lithium ion batteries, RFB's can span from the kW to multi MW power storage systems. The nickel complexes described herein have demonstrated redox potentials >3 V which is at least twice the aqueous limit. We are interested in partnering with battery developers to further advance this technology to the product prototype stage.
