Unique Flow Battery Powers New E-Sportlimousine

Over the years, a number of companies have come up with new technologies promising to boost the efficiency of cars by previously unseen levels. They tend to roll out fancy concepts, typically with wild performance claims, but these companies never seem to be able to progress beyond the concept stage for whatever reasons (we’re sure you can guess why).

A previous Quant concept was shown by La Vecchia in 2010 and was developed together with Swedish supercar brand Koenigsegg. La Vecchia has since joined forces with Germany’s Bosch and has now rolled out the new Quant e-Sportlimousine.

The latest concept is an electric sedan that utilizes La Vecchia’s nanoFLOWCELL technology. The concept’s electric drive system is rather conventional, albeit there are four separate motors producing 920 horsepower, but its rechargeable energy storage system, called a flow cell, is unique, at least in the world of autos.

A flow cell is essentially an electrical storage device that combines aspects of both conventional batteries, like the lithium-ion units found in a laptop, with those of a fuel cell, where a chemical reaction between two substances forms electrical energy, like in a hydrogen fuel cell stack.

In the flow cell, two different substances, in this case liquid electrolytes (usually metallic salts in aqueous solution), are kept in small reservoirs separated by a membrane. When the liquid electrolytes are circulated, a process known as ion exchange takes place and creates a flow of electrical current, which can then be used to power the drivetrain.

nanoFLOWCELL’s version of the technology is said to feature high charge density, high performance density, and low weight compared to conventional energy storage systems such as lithium-ion batteries. La Vecchia claims the nanoFLOWCELL has a five-time greater performance-to-weight ratio than current lithium-ion technologies, which means its driving range would be five times greater than a lithium-ion battery of the same weight.

In the Quant e-Sportlimousine, the flow cell is said to have a storage capacity of 120 kWh. By comparison, the Tesla Model S’s biggest battery has an 85 kWh capacity. The driving range is a claimed 372 miles.


Charging is done by replacing the electrolytic solutions, though La Vecchia doesn’t provide much detail here.

The plan now is to get four working prototypes built so that real-world testing can begin. La Vecchia hopes to eventually have a small production run of cars powered by his nanoFLOWCELL technology.
