NanoFlowCell-Quant-8

This car uses a electrolyte flow cell power system that is newly certified for use on Europe’s roads. They call it the Quant e-Sportlimousine. Not only does it run on salt water, but it’s said to be able to top 217 miles per hour.
In its introductory video, it describes the solutions simply as salt water. The producer confirmed that the full truth is a bit more complex, as the electrolytes contain a mix of metal salts and other ingredients.

The high- and low-charge solutions are stored in separate 200-liter tanks in the rear of the Quant, being pumped forward through a central cell, separated from each other by a thin membrane. This creates electricity, which flows into two supercapacitors, where it is stored and managed, released on acceleration to power the four three-phase wheel motors. Nanoflowcell says the flow technology operates with 80 percent internal efficiency.
