A Review of Fabrication Technologies for Carbon Electrode-Based Micro-Supercapacitors

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 their power density, long cycle lifetime and charge discharge. Recent developments on micro-supercapacitors focus improving overall electrochemical performance, mechanical properties. In this review, different types configurations briefly introduced. Then, advances carbon electrode materials presented, including activated carbon, nanotubes, graphene, onion-like carbide-derived carbon. electrolytes used studies also treated, aqueous, organic, ionic liquid, solid-state, quasi-solid-state electrolytes. Furthermore, latest fabrication techniques micro-supercapacitors, such as deposition, coating, etching, printing technologies, discussed review electrode-based micro-supercapacitors.
