Accelerated battery degradation can be caused by charging and discharging patterns, such as repeatedly using the entire capacity of a battery, or repeated rapid charging. Fig. 2 depicts the Ragone plot highlighting the PD and ED of the conventional capacitors, FCs, batteries, SCs and lithium-ion capacitors (LICs) [21].
Capacitors have a limited number of charge-discharge cycles before their performance starts to degrade, while batteries can be recharged and discharged many times before they lose their capacity. In terms of cost, capacitors are generally more expensive than batteries, especially when it comes to larger energy storage capacities.
