The very fast evolution in wearable electronics drives the need for energy storage micro-devices, which have to be flexible. Micro-supercapacitors are of high interest because of their high power density, long cycle lifetime and fast charge and discharge. Recent developments on micro-supercapacitors focus on improving the energy density, overall electrochemical performance, and mechanical properties. In this review, the different types of micro-supercapacitors and configurations are briefly introduced. Then, the advances in carbon electrode materials are presented, including activated carbon, carbon nanotubes, graphene, onion-like carbon, and carbide-derived carbon. The different types of electrolytes used in studies on micro-supercapacitors are also treated, including aqueous, organic, ionic liquid, solid-state, and quasi-solid-state electrolytes. Furthermore, the latest developments in fabrication techniques for micro-supercapacitors, such as different deposition, coating, etching, and printing technologies, are discussed in this review on carbon electrode-based micro-supercapacitors.

Recently core/shell nanostructures including nanotubes, nanowires, and nanofibers have a considerable attension because multiple or enhanced functionality can be obtained by the synergistic effect of different materials in the formation of a core/shell structure. In this work, porous carbon/carbon core/shell carbon electrode (P-C/C-CE) composed of core graphene and disordered shells were prepared to obtain a new type of carbon electrode materials. The disordered carbon shells were prepared by coating of polyaniline onto the graphene by in-situ polymerization in the presence of nano-sized silica and subsequent carbonization at 850°C. After carbonization, P-C/C-CE showed the hollow structure and crystallinity. In addition, P-C/C-CE exhibited superior electrochemical performance compared to graphene and graphene/PANI composites, which was attributed to the high surface area of P-C/C-CE and the presence of nitrogen groups formed onto carbon electrode after the carbonization of shell polyaniline.
