Abstract:  With the sustainable development of green energy storage devices, supercapacitors that hold both high energy density and power density have shown significant potential in the energy storage filed. In this work, we reviewed the advancement achieved in the supercapacitor electrodes, including electrical double-layer, pseudo-capacitive and their hybrid electrodes. On the basis of the electrodes, the typical prototypes of all-solid-state supercapacitors have been intensively discussed with the employment of solid-state electrolytes, and key parameters for promoting the energy density of the devices have been summarized. According to the critical issues in the electrodes and electrolytes, the perspective toward supercapacitor research and development has been proposed.

Key words: supercapacitors, energy storage devices, carbon materials, green energy
