JenaBatteries GmbH and BASF are cooperating in the production of an electrolyte for a battery technology that is particularly suitable for stationary storage of electricity from renewable energy sources and for stabilizing conventional transmission grids. JenaBatteries, which has developed this technology based on a redox flow battery (RFB) with organic materials, has the first commercially available technology of this kind. RFBs use two liquid organic electrolytes separated by a membrane and stored in separate tanks. BASF will supply one of the two electrolytes as part of the collaboration. This battery material is based on an amine, a chemical intermediate that BASF can produce on an industrial scale. JenaBatteries plans to market the first RFB this year. Background. RFBs store electrical energy in chemical compounds. The two reaction partners are present in dissolved form and circulate in two separate circuits. The ion exchange between the two energy-storing electrolytes takes place […]
