A capacitor battery is actually a capacitor , but its capacity is much larger than that of a normal capacitor. Its external performance is the same as that of a battery. Therefore, it is called a “capacitor battery†and is also called a “super capacitorâ€. With the intensive research and development of supercapacitor batteries and the maturity of technology, supercapacitor batteries have entered the application stage and are becoming more market-oriented and commercialized.
Capacitor battery features:
(1) The charging speed is fast, and it can reach more than 95% of its rated capacity by charging for 10 seconds to 10 minutes;
(2) The cycle life is long, the frequency of deep charge and discharge cycles can reach 10,000 to 500,000 times, and there is no “memory effectâ€;
(3) The high current discharge capacity is super strong, the energy conversion efficiency is high, the process loss is small, and the high current energy cycle efficiency is ≥90%;
(4) High power density, up to 300W/KG~5000W/KG, which is equivalent to 5~10 times of ordinary battery;
(5) There is no pollution in the composition, production, use, storage and dismantling of raw materials, which is an ideal green power source;
(6) The charging and discharging circuit is simple, no charging circuit like rechargeable battery is needed, and the safety factor is high, and maintenance is free for long-term use;
(7) Good ultra-low temperature characteristics, the temperature range is wide -40 ° C ~ +70 ° C;
(8) Easy to detect, the remaining power can be read directly;
(9) The capacity range is usually 0.1F--1000F.
Supercapacitor batteries are also electric double layer capacitors. They are the largest capacity among the electric double layer capacitors that have been put into mass production in the world. The basic principle is the same as other types of electric double layer capacitors. The electric double layer structure composed of the electrolyte obtains an extremely large capacity.
