The hybrid capacitor is designed to attain a high energy density. Compared to symmetric capacitors, hybrid capacitors have a large potential window and a high specific capacitance . In general, hybrid capacitors employ three types of electrodes: composite electrodes, battery-type electrodes, and asymmetric electrodes.
In hybrid capacitors, when the output power of the battery is insufficient, the supercapacitors can be used for the peak power demand for a short period and since the energy density of the supercapacitors is very low, the batteries are used to store the energy. The supercapacitors here are a power buffer between the battery and the load.
Compared to symmetric capacitors, hybrid capacitors have a large potential window and a high specific capacitance . In general, hybrid capacitors employ three types of electrodes: composite electrodes, battery-type electrodes, and asymmetric electrodes. The types of hybrid electrodes are summarized in Fig. 7.
Utmost, the sloping potential profile of the EDLC component in the electrochemical response is detrimental for most of the applications where a constant power supply is required. To overcome these limitations, a hybrid electrode, which makes synergistic use of capacitor and battery components rather than a merely additive composite, is necessary.
