The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid material that has comparable performance data to currently utilized batteries. Usually, energy storage is associated with batteries and accumulators that provide energy for electronic devices. Sustainable material provides high performance The team working with TUM chemist Roland Fischer has now developed a novel, powerful as well as sustainable graphene hybrid material for supercapacitors. Hybrid materials: Nature is the role model The researchers are betting on a new strategy to overcome the performance limits of standard materials – they utilize hybrid materials. "Nature is full of highly complex, evolutionarily optimized hybrid materials – bones and teeth are examples.
