PAGOODA manufactures supercapacitors Supercapacitors, also known as electrochemical capacitors, electric double-layer capacitors, gold capacitors, and Farad capacitors, are electrochemical components developed from the 1970s and 1980s to store energy through polarized electrolytes. Different from traditional chemical power sources, it is a power source with special properties between traditional capacitors and batteries, mainly relying on electric double layers and redox pseudocapacitive charges to store electrical energy. Features: (1) The charging speed is fast, charging for 10 seconds to 10 minutes can reach more than 95% of its rated capacity (2) Long cycle life (about 15-16 years), the number of deep charge and discharge cycles can reach 10,000 to 500,000 times, and there is no "memory effect" (3) Super high current discharge capacity, high energy conversion efficiency, small process loss, high current energy cycle efficiency ≥ 90% (4) High power density, up to 300W/KG~5000W/KG, equivalent to 5~10 times that of batteries (5) The raw material composition, production, use, storage and dismantling process of the product are free of pollution, which is an ideal green power source (6) The charging and discharging circuit is simple, no charging circuit like a rechargeable battery is needed, the safety factor is high, and long-term use is maintenance-free (7) Good ultra-low temperature characteristics, wide temperature range -40℃～+70℃ (8) The detection is convenient, and the remaining power can be directly read out (9) The capacity range is usually 0.1F--1000F
