3D printed interdigitated supercapacitor using reduced graphene oxide-MnO /MnO based electrodes.

In this study hybrid nanocomposites (HNCs) based on manganese oxides (MnO /MnO) and reduced graphene oxide (rGO) are synthesized as active electrodes for energy storage devices. Comprehensive structural characterizations demonstrate that the active material is composed of MnO /MnO nanorods and nanoparticles embedded in rGO nanosheets. The development of such novel structures is facilitated by the extreme synthesis conditions (high temperatures and pressures) of the liquid-confined plasma plume present in the Laser Ablation Synthesis in Solution (LASiS) technique.
