Advantages of Electric Double Layer Capacitors

  Advantages of electric double layer capacitors : long life, somewhat degraded over hundreds of thousands of charge cycles. Due to the high number of charge-discharge cycles (millions or more compared to 200 to 1,000 of most commercially available rechargeable batteries) the capacitor will last for the entire life cycle of most devices, which makes the device environmentally friendly. Rechargeable batteries are usually worn out for several years, and their highly active chemical electrolytes present handling and safety concerns. It is possible to charge only under favorable conditions, an ideal speed, and for some chemistries, to optimize battery life as little as possible. Electric double layer capacitors are combined with batteries as a charge regulator, store energy from other sources for load balancing purposes, then use rechargeable batteries, at the right time, any excess energy can help;

low cost per cycle;

good reversibility ;

very high charge and discharge rates;

very low internal resistance (ESR) and consequent high cycle efficiency (above 95%) and very low heating water;

high output power;

high specific power. According to the test results of ITS (Institute of Transportation Research, Davis, CA), the specific power of electric double layer capacitors can exceed 6 kW/kg with 95% efficiency [13];

improved safety, non-corrosive electrolyte and Low toxicity material;

simple charging method, no full charge detection is necessary, no danger of overcharging; when used in

conjunction with rechargeable batteries, the EDLC provides energy for a short period of time in some applications, reducing battery bicycle taxes and extend your life.
