To advance the symbiosis between electromobility and lightweight construction, engineers from the Fraunhofer Institute for Chemical Technology ICT in Pfinztal, Germany, are developing manu- facturing concepts that have one goal – they want to gradually replace individual components in the vehicle with lightweight ones.

“The battery housing can withstand a crash, assu- ming a ten-fold gravitational acceleration.“ And even if a sharp object collides with the housing at 60 km/h (45mph), the highly sensitive battery on the inside remains intact. In addition, the 16 lithi- um-ion modules are protected from humidity, and a semi-permeable membrane to equalize pressure also guarantees that the batteries are able to “brea- the.“
What make the new battery protection so special are the new fiber-reinforced composite materials.
The fact that this is possible is proven by the re- searchers with the Artega GT, a sports car that was modified into a prototype with an electric drive, where the electric motor is located in the rear. The experts, along with colleagues from the Fraunhofer Institutes for Mechanics of Materials IWM, for Structural Durability and System Reliability LBF and for High-Speed Dynamics, Ernst-Mach Insti- tut EMI, have developed a mass-production-ready, crash-safe battery housing that meets strict requi- rements. The battery housing that surrounds the battery that weighs 340 kilograms (749.57 lbs.) only weighs 35 kilograms (77.16 lbs.).
“Traditional solutions made of steel weigh up to 25% more,“ said Manfred Reif, project manager.
Researchers from Seoul National University and the Samsung Advanced Institute of Technology, which are both located in Korea, have developed a simple but efficient low-temperature route to prepare metallic NW-graphene (MN-G) hybrid nanostructures for flexible field emission devices.
