一. Supercapacitor battery
Supercapacitor battery is also called gold capacitors and farad capacitors. They store energy by polarizing electrolytes and belong to one type of electric double layer capacitors. Since the process of energy storage does not undergo a chemical reaction, this energy storage process is reversible because the supercapacitor can be repeatedly charged and discharged hundreds of thousands of times. Supercapacitors generally use activated carbon electrode materials, which have the characteristics of large adsorption area and high electrostatic storage, and are widely used in new energy vehicles.
二. the characteristics of supercapacitor battery
(1) The charging speed is fast, as long as it is charged for more than 95% of its rated capacity by charging for several tens of seconds to several minutes; now it takes several hours to charge the lead-acid battery with the largest area.
(2) The cycle life is long, and the number of deep charge and discharge cycles can reach 500,000 times. If the super capacitor is charged and discharged 20 times a day, it can be used continuously for 68 years. If compared to lead-acid batteries, it has a service life of 68 years and has no “memory effect”.
(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) The power density is high, up to 300W/kg~5000W/kg, which is equivalent to dozens of times of ordinary batteries; the specific energy is greatly improved, the lead-acid battery can only reach 200W/kg, and the supercapacitor battery is currently developed. Up to 10 KW/kg.
(5) The raw material composition, production, use, storage and dismantling process of the product are not polluted, and it is an ideal green environmental protection 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 the maintenance is long-term maintenance-free;
(7) Good ultra-low temperature characteristics, the ambient temperature range is as wide as -40 ° C ~ +70 ° C;
(8) Easy to detect, the remaining power can be read directly;
(9) The monomer capacity range is usually 0.1F–3400F.
三. The application of supercapacitor battery
Supercapacitor power batteries are widely used as power balance power sources for lifting devices and can provide super-current power. They are used as starting power sources for vehicles, and have higher starting efficiency and reliability than conventional batteries. They can replace traditional batteries in whole or in part. The traction energy used as a vehicle can produce electric vehicles, replace traditional internal combustion engines, and transform existing trolley buses; it can be used to ensure the smooth start of tanks, armored vehicles and other vehicles as a pulse energy source for laser weapons. It can also be used for energy storage in other electromechanical devices.
