nanoFlowcell 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,[1] Quant F[2] and Quantino prototype vehicles.[3] Similar to regular redox flow batteries, the nanoFlowcell battery uses electrolyte fluids to generate electricity from chemical compounds. nanoFlowcell claims that, unlike the electrolytes in vanadium flow batteries or polysulfide bromide flow batteries, the electrolyte used in the nanoFlowcell is non-toxic and environmentally compatible[citation needed]. The company claims that 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.[4] nanoFlowcell states that production cost for its "non-flammable and non-explosive" electrolyte is below 10 cents per litre.[5]

While European research institutes and experts question the adequacy of flow cell designs for use in electric cars,[6] scientists at the Illinois Institute of Technology (IIT) in the USA recently claimed to have developed an equally powerful flow cell designed for use in electric vehicles.[7]

nanoFlowcell has registered offices in Kilchberg, Switzerland [8] and London, United Kingdom.[9]

QUANT Prototypes[edit]

QUANT FE premiere at the 2016 Geneva International Motor Show

Under the name QUANT (derived from quantum mechanics), nanoFlowcell Holdings is developing applications for its nanoFlowcell battery technology, mainly electric vehicles such as the QUANT E, QUANT FE and Quantino. The Quantino is the latest electric prototype vehicle produced by nanoFlowcell engineers for their battery testing purposes. The road-legal version of the Quantino was first introduced at the Geneva International Motor Show in 2016, together with its more powerful sibling QUANT FE.[10][11]

The Quantino and QUANT FE prototype vehicles have been used for non-public technology presentations towards the automobile industry in 2016 to further demonstrate the use and advantages of flow cell technology in electric cars. Several journalists who drove Quantino and QUANT FE in public testings confirmed functionality of the nanoFlowcell's flow cell technology.[12][13][14] The Quantino allegedly has been using 12 kWh per 100 km in a mixed test.[15]

bi-ION Electrolyte[edit]

Similar to regular modern flow cells, nanoFlowcell is producing electricity from liquids. However, the electrolyte is not common salt water as commonly stated in several internet forums, but the electrolyte solution bi-ION consists of a conductive liquid - organic and inorganic salts dissolved in water - and the electrolytes themselves, nano-particles which are specific molecules designed by nanoFlowcell Holdings Ltd. While dissolved redox salts are responsible for the energy transfer in conventional redox flow batteries, the bi-ION electrolyte is an energy storage medium whose suspended nano-particles permit a considerably higher energy density than regular redox electrolyte liquids.[16]


There is a lack of scientific understanding or patents describing how water with metallic salts can be used to produce electric energy with the efficiency and energy density that the company claims, and no independent third party measurements confirming the claims are available.[17] The claimed performance contradicts research that has been done on flow batteries.[18] It has been said that "there is no solid proof just yet that the QUANT e actually works and performs as advertised".[19]

The Quant 48 Volt delivers 560 kW at 48 V, with 140 kW going to each motor.[20] This means the current going to each motor is equal to 2917 Amps. The company fails to explain how it deals with cooling those cables.[21]
