(2) Long cycle life. The number of deep charge and discharge cycles can reach 500,000. If the supercapacitor is charged and discharged 20 times a day, it can be used continuously for 68 years. Compared with lead-acid battery, its service life can reach 68 years, and there is no "memory effect".
(3) Excellent high-current discharge capability, high energy conversion efficiency, low process loss, and high-current energy cycle efficiency ≥ 90%;
(4) The power density is high, which can reach 300 Wh/kg ~ 5,000 Wh/kg, which is dozens of times that of ordinary batteries; The specific energy is greatly improved. Generally, lead-acid batteries can only reach 200Wh/kg. At present, the research and development of electric double layer capacitors has reached 10kWh/kg.
(5) There is no pollution in the composition, production, use, storage and disassembly of raw materials, and it is an ideal green power supply;
(6) The charging and discharging circuit is simple, charging circuits such as rechargeable batteries are not needed, the safety factor is high, and long-term use is maintenance-free;
(7) Excellent ultra-low temperature characteristics with a wide temperature range of-40℃ ~+70℃;
(8) The detection is convenient, and the remaining power can be directly read out;
(9) The monomer capacity is usually between 0. 1F-3400F and 3400F.
