As a result, these SCs are being widely considered as preferable alternatives for energy storage applications. Flexible solid-state supercapacitor devices typically consist of many components, such as flexible electrodes, a solid-state electrolyte, a separator, and packaging material .
A solid pseudocapacitive electrochemical capacitor enabled by a polymer electrolyte and Mo x N electrodes has been developed and has demonstrated ultra-high rate performance . The corresponding solid-state SC can deliver 1 mF/cm 2 at 100 V/s and achieve a 10 ms time constant.
The resultant flexible SCs showed high specific capacitance, good cycling stability, and enhanced energy density and power density (1.64 Wh/kg and 0.67 kW/kg). Another type of carbon, exfoliated graphite (EG), is proposed as an electrode material for solid-state electrochemical capacitors .
Its assembly in an ultra-flexible all-solid-state thin-film supercapacitor for the first time possessed great specific capacitance of 660.8 F cm −3 and demonstrated the best record among all-solid-state thin-film supercapacitors.
Electrochemical capacitors, or named as supercapacitors (SCs), combined with exceptionally long cycle life, very high power density and enhanced energy density, afford a smart maneuver , . Figure 1 a shows the Ragone plot for the most important energy storage systems.
