In the field of energy storage and in particular for supercapacitors, graphene is by all accounts the advanced material of choice for years to come. Graphene has already been claimed as a champion material for supercapacitors providing large active area for capacitive double-layer storage. What then could be better than graphene for energy storage?

Hybrid materials offer the opportunity of building synergies thus leading to improved performance over their individual components.[1] In that way, hybrids based on graphene and a variety of molecular species[2.3] or extended phases[4] have been used to design materials with enhanced activity. This approach has been applied to Graphenes leading to materials with a perfect combination of properties for their use as active electrode materials in energy-storage devices, namely, a combination of conductivity-electroactivity as well as a combination of double-layer capacitive energy storage (graphene) and faradaic energy storage in a single material with a dual energy storage mechanism.[1] 

A wise choice of electroactive species can thus improve the energy density of graphene-based supercapacitors through hybridization. 

Furthermore, in our group we have gone beyond the conventional solid state electrode format and have developed graphene electroactive nanofluids as liquid electrodes for flow cells. This novel electrode format is also prone to the development of hybrid materials. In this conference this general hybrid approach, with some emphasis on our own group results will be presented in relation to graphene-based materials for energy storage and illustrative examples discussed.
