The EU-supported ElectroGraph project succeeded in developing graphene-based supercapacitor electrodes. Graphene enhances the surface area of the electrode, which makes it a great replacement for activated carbon (the currently used material). To demonstrate this, the consortium developed a car side-mirror that uses the graphene-enhanced supercapacitor charged by a solar panel.

The ElectroGraph electrodes surpassed commercially available ones by 75% in terms of storage capacity. ElectroGraph was coordinated by the Fraunhofer IPA Institute, and it mostly looks into supercapacitor applications for the automotive industry.
