 Battery-powered controlled car
Forget hour-long charge times the electric car. Fill up with fresh electrolyte in the battery at the gas station and drive.
It is the idea behind a research project at the German Fraunhofer Institute for Chemical Technology in Pfinztal. Battery researchers use so-called redox flow batteries using liquid electrolyte. At low charge to drive into the gas station, empty the used electrolyte and loading new. The old electrolyte can then be recharged at the station and use it again. Battery type is not a new one out Jens Noack, a battery of scientists. Two liquid electrolyte containing metal ions flow through porous graphite electrodes separated by a membrane, which allows protons to pass through. Power occurs when the electrodes. The downside has already been to these batteries have much lower capacity than lithium-ion batteries, for example, perhaps only one quarter as much. But now, the Fraunhofer researchers succeeded in raising the capacity so the battery can be compared with lithium-ion batteries.
It now remains to build more cells to the batteries and optimize them.
Together with colleagues at the University of Applied Sciences in
Luneburg has built models that run on prototype batteries.
