Their electrostatic charge storage mechanism and lower internal resistance (compared to batteries) help minimize heat generated by impeding charge flow and prevent heat-generating chemical reactions. Batteries store energy as chemical energy, which is more energy-dense than electrostatic energy storage in supercapacitors.
Supercapacitor specific power is typically 10 to 100 times greater than for batteries and can reach values up to 15 kW/kg. Ragone charts relate energy to power and are a valuable tool for characterizing and visualizing energy storage components.
Supercapacitors can be used to supplement batteries in starter systems in diesel railroad locomotives with diesel–electric transmission. The capacitors capture the braking energy of a full stop and deliver the peak current for starting the diesel engine and acceleration of the train and ensures the stabilization of line voltage.
Commercial lithium-ion batteries are widely used to power electric vehicles due to their high energy density, but supercapacitors are increasingly finding applications in the automotive and transportation industries.
In a battery, charge and discharge are electrochemical reactions. Supercapacitors store charge electrostatically on their high surface-area plates. The devices store less energy, but they can charge or discharge in seconds. Therefore, supercapacitor applications are primarily used to supply short bursts of power.
The biggest drawback compared to lithium-ion batteries is that supercapacitors can't discharge their stored power as slowly as a lithium-ion battery, which makes it unsuitable for applications where a device has to go long periods of time without charging.
