Super capacitor is widely used in more and more areas, because the super capacitor can provide higher instantaneous power than the battery. Its important applications include the power which mobiles supply for flash, and accept recharge of the battery, this can extend talk time and battery life, but also save cost for engineers. Besides,super capcitor can also be used in smart meter, solar lamps, toys, LED display, electric cars, muddy co-powered cars, car audio, power tools, wind power generation, industrial UPS, peak power compensation devices.
Super capacitor, also known as electric double layer capacitors, is to store energy through the electrolyte polarization. It is an electrochemical device, but it has no chemical reaction in the process of energy storage, this energy storage process is reversible, because of this, the super capacitor can be charged for thousands of times.
Compared with conventional batteries, stored electricity of super capacitors is not too much. So many home rechargeable (Plug-in) devices, for example, electric cars, super-capacitor can not be used as power supply equipment, but used together with fuel cells. Super capacitors have the advantage of rapid discharge. In addition, the charging time is short, it can be fully charged for only a few minutes or even seconds, besides,the performance will not be reduced after recharge many times.
At present,super capacitor has been used in digital cameras and other products, for example,flash which need a lot of energy in short time. Experts say the major challenge of super capacitor is how to improve the operating voltage so that it can be operated in high-voltage environment. Experts say the super capacitor is a good environmentally-friendly energy, it will make power supply perfect when the super capacitors are together with batteries, fuel cells, solar or wind power and other power generation. Super capacitors also use environmentally friendly materials and price is easy for consumers to accept.
