• Supercapacitor abstract "Supercapacitor (SC), formerly electric double-layer capacitor (EDLC) or ultracapacitor, is the generic term for a family of electrochemical capacitors. Supercapacitors don't have a conventional solid dielectric. The capacitance value of an electrochemical capacitor is determined by two storage principles, which both contribute indivisibly to the total capacitance: Double-layer capacitance – Electrostatic storage achieved by separation of charge in a Helmholtz double layer at the interface between the surface of a conductive electrode and an electrolyte. The separation of charge is of the order of a few ångströms (0.3–0.8 nm), much smaller than in a conventional capacitor. Pseudocapacitance – Faradaic electrochemical storage with electron charge-transfer, achieved by redox reactions, intercalation or electrosorption.The ratio of the two storage principles can vary greatly, depending on the design of the electrodes and the composition of the electrolyte. Pseudocapacitance can be as much as 10× that of double-layer capacitance.Supercapacitors are divided into three families, based on electrode design: Double-layer capacitors – with carbon electrodes or derivates with much higher electrostatic double-layer capacitance than electrochemical pseudocapacitance Pseudocapacitors – with metal oxide or conducting polymer electrodes with a high amount of electrochemical pseudocapacitance Hybrid capacitors – capacitors with asymmetric electrodes, one of which exhibits mostly electrostatic and the other mostly electrochemical capacitance, such as lithium-ion capacitorsSupercapacitors bridge the gap between conventional capacitors and rechargeable batteries. They store the most energy per unit volume or mass (energy density) among capacitors. They support up to 10,000 farads/1.2 volt, up to 10,000 times that of electrolytic capacitors, but deliver or accept less than half as much power per unit time (power density).By contrast, while supercapacitors have energy densities that are approximately 10% of conventional batteries, their power density is generally 10 to 100 times greater. This results in much shorter charge/discharge cycles than batteries. Additionally, they will tolerate many more charge and discharge cycles than batteries.In these electrochemical capacitors, the electrolyte is the conductive connection between the two electrodes. This distinguishes them from electrolytic capacitors, in which the electrolyte is the cathode and thus forms the second electrode.Supercapacitors are polarized and must operate with the correct polarity. Polarity is controlled by design with asymmetric electrodes, or, for symmetric electrodes, by a potential applied during manufacture.Supercapacitors support a broad spectrum of applications, including: Low supply current for memory backup in static random-access memory (SRAM) Power for cars, buses, trains, cranes and elevators, including energy recovery from braking, short-term energy storage and burst-mode power deliveryExceptional are the manifold different trade or series names used for supercapacitors, such as: APowerCap, BestCap, BoostCap, CAP-XX, DLCAP, EneCapTen, EVerCAP, DynaCap, Faradcap, GreenCap, Goldcap, HY-CAP, Kapton capacitor, Super capacitor, SuperCap, PAS Capacitor, PowerStor, PseudoCap, Ultracapacitor.".
