Dr David Eisenberg and Prof. Gadi Rothenberg of the University of Amsterdam’s Van ‘t Hoff Institute for Molecular Sciences have invented a new type of supercapacitor material with a host of potential applications in electronics, transportation and energy storage devices. The UvA has filed a patent application on this invention.
Eisenberg and Rothenberg discovered the supercapacitor material during sideline experiments as part of the Fuel Cells project of the Research Priority Area Sustainable Chemistry. Originally, the materials were developed as solid catalytic electrodes for fuel cells. By modifying the surface of these materials the scientists created a highly porous yet well-structured compound, with ample sites for fast redox reactions, inspiring the successful testing for supercapacitance.
The new material combines several practical advantages: It is light, cheap, and non-toxic, and it can be prepared easily on a large scale. This last aspect is crucial for industrial applications, according to Eisenberg: ‘Companies making electronic devices look for low-cost, highly reproducible materials with a low environmental impact. The literature abounds with reports of high-performance electronic materials, but these will only be applied if they can be made cheaply in large quantities’.
