nanoFlowcell Holdings plc is a Swiss flow cell battery research and development company.

nanoFlowcell claims to have developed the first flow battery small enough to be used in electric cars. Its battery, also branded nanoFlowcell, was first presented in the Quant E, Quant F and Quantino prototype vehicles. Similar to regular redox flow batteries, the nanoFlowcell battery uses electrolyte fluids to generate electricity from chemical compounds. nanoFlowcell uses, unlike the electrolytes in vanadium flow batteries or polysulfide bromide flow batteries, proprietary molecules as charge carriers; the electrolyte used in the nanoFlowcell is non-toxic and environmentally compatible. The electrolyte used in the nanoFlowcell battery has an energy density of 600 Wh per litre, which is ten times the energy density of regular redox flow cells. nanoFlowcell states that mass production cost for its "non-flammable and non-explosive" electrolyte is below 10 cents per litre.
