Car Battery of the Future

At the research center of the German technical university of Baden Württemberg (Karlsruhe Institut für Technologie: KIT), Maximilian Fichtner and Horst Hahn have developed a new powerful and everlasting battery, which will probably be used in hybrid cars in the near future. By using fluoride in metal sheet cells instead of lithium, they have considerably raised the battery energy storage capacity. With the old lithium battery, which is composed of many single ion cells, an electric car has a maximum range of 160 km per hour, but using fluoride ions, which make electrons flow in small cells, the performance has been increased four times. Thus, fitted with the new fluoride battery, the university's electric car has been able to run a maximum of 550 km during the tests, without being recharged. The fluoride battery also has other advantages over the old lithium battery; it is lighter, smaller, and more compact, taking up much less space in the car.
