When compared to traditional capacitors, they possess a lower power density but a higher energy density . Supercapacitors can serve as rapid starting power sources for electric vehicles, as well as balancing power supplies for lifting equipment.
Supercapacitors are classified into pseudo-capacitors and electric double-layer capacitors (EDLCs) based on the energy storage mechanisms [, , ].
The selection of a proper supercapacitor from a manufacturer depends not only on the application, power, energy requirement, spacing, cost, and the expected life of the device but also on the reviews from previous customers. 4. Materials for supercapacitor
The dielectric materials can withstand higher electric fields without breaking down, allowing traditional capacitors to have much higher voltage ratings, often in the range of hundreds of volts. Table 1. Energy storage capacities of supercapacitors and capacitors.
Spell Technologies, Skelton Technologies, Maxwell Technologies, Eton, and LSMtron are the leading manufacturers with supercapacitors with the highest capacitance. Table 4 compares commercially available supercapacitors with their electrical specifications, such as rated voltage, rated capacitance, ESR, specific energy, and specific power.
Taxonomy of supercapacitors. Common capacitors have a dielectric material which separates double conducting electrodes. Charges of opposite nature gather on both the electrode surfaces while the capacitor is applied with voltage.
