In Endurance Batteries
Security At Its Best
How safe are the new hybrid and electric cars? If the energy is no risk? Keep the batteries, the temperature fluctuations in the car from? They explode if they are damaged? To examine these questions and more are to be subject Researchers at the Fraunhofer Institute for Chemical Technology ICT in Pfinztal near Karlsruhe batteries of different hardness tests.

What can withstand loads of batteries?
Check that the batteries can withstand mechanical, thermal and electrical stress. What happens during a crash? As the batteries to respond to rapid changes in temperature or vibration? Puffed up the batteries when they are overloaded? Burns energy when it is lit?
“To determine the risk and the damage that we observe the behavior of the battery during the entire abuse testing under a variety of aspects. Both the temperatures and the rising and escaping gases for the purpose of an accurate risk analysis measured and evaluated, “says Dr. Jens Tübke from the Fraunhofer Institute for Chemical Technology ICT. The researchers are developing security concepts derived from them.

Hybrid Car
New Materials
In addition to the “ill-tests”, the researchers will also investigate whether there are suitable, for example, certain cells and batteries used in hybrid vehicles. Only proceed if the systems in these studies no risk, large batteries can be installed in a vehicle.
Also contributing to the safety of batteries provide the characterization of the used battery components and their material properties. The development of new battery materials is one of the current work of the “Applied Electrochemistry” of ICT and the “electrochemical energy storage and conversion” of the Fraunhofer Institute for Silicate Research ISC. The focus is on the synthesis and characterization of electrodes and the development of polymer electrolytes and ionic liquids for lithium-ion and lithium polymer batteries.
