Although ruthenium oxide nanoparticles (RuO2), graphene, and their composites have been widely used as supercapacitor electrode materials, transparent supercapacitors of these materials have been rarely investigated.
The TiO2-bronze/nitrogen-doped graphene nanocomposites have the potential for fast-charging and have high stability, showing potential as an anode material in advanced power batteries for next-generation applications.
Wood derived carbon–polyaniline composites exhibit comparable specific capacitance (347 F g−1) and energy density (44.4 W h kg−1) to similar materials.
