Design of new metallic oxide-carbon hybrid composites for supercapacitors electrodes - MOC@SUPCAP

The M.Era-Net project entitled “Design of new metallic oxide-carbon hybrid composites for supercapacitors electrodes” has been successfully developed by the proposed institutions, namely IST/Portugal, Sintef/Norway, and NTNU/Norway. The above-mentioned project gave rise to nine publications, which are all dedicated to the supercapacitors field. Besides these interesting publications, one of the materials utilized on the project, carbon foam as negative electrode, motivated a Portuguese company (C2C-NewCap - ) to successfully test our approach of fabricating hydroxides-oxides and carbon-based materials as hybrid supercapacitors in its production line. In fact, this fabrication route has been published in one of the best journals devoted to power sources, the “Journal of Power Sources”, in which it is demonstrated the production of Co(OH)2/carbon nanofoam composite as supercapacitor electrode operating at 2 V in friendly aqueous medium. In addition, we have dealt with graphene-based active materials which are undoubtedly the most studied materials in the current state-of-art and have extraordinary chemical and physical properties leading them to a myriad of applications.

In summary, we believe that our project has significantly contributed to both academia and industry fields and is part of an essential area for the sustainable and economic development of all countries around the world which is renewable energy.



In this project, different materials, e.g. MnO2, Co(OH)2, NiO, reduced graphene oxide (rGO), have been produced devoted to supercapacitor applications. Most of them have been obtained by electrodeposition technique which is no doubt a simple, versatile, and efficient approach to fabricate supercapacitor materials.
