Supercapacitors have excellent pulse charge and discharge and large-capacity energy storage performance. The monomer capacity has reached 10,000 Farad is an energy storage component between the electrostatic capacitor and the battery. Compared to conventional capacitors and batteries, supercapacitors have the advantage that many batteries cannot match.
1. Has a very high power density. The power density of the capacitor is 10 to 100 times that of the battery, which can reach 10 kW / kg, and can discharge hundreds to thousands of amperes in a short time. This feature makes supercapacitors ideal for short-term, high-power output applications.
2. Charging speed is fast. Supercapacitor charging is a physical process of charging and discharging electric double layer or a fast and reversible chemical process on the surface of an electrode material. It can be charged by a large current and can complete the charging process in several tens of seconds to several minutes. It is really fast. Charging.
The battery takes a few hours to complete the charging, and it takes dozens of minutes to use the fast charging.
3. Long service life. The electrochemical reactions occurring during the charging and discharging of supercapacitors have good reversibility, and it is not easy to appear a series of end-of-life phenomena such as crystal transformation, shedding, and dendritic penetrating membranes like active substances in batteries. Carbon Capacitor Theory The cycle life is infinite, actually more than 100,000 times, 10 to 100 times higher than the battery.
4.Excellent low temperature performance. Most of the charge transfer that occurs during charging and discharging of the supercapacitor is performed on the surface of the electrode active material, so the capacity decays very little with temperature. The capacity of the battery can be as high as 70% at low temperatures.
Handling Precautions and Guidelines
1. Voltage drop
Pay particular attention to the instantaneous working current and voltage drop due to the supercapacitor’s interal resistance when used in backup mode. The discharging current level is different depending on the supercapacitor’s inernal resistance.
2. Series connection
When connecting supercapacitors in series, add a bleeder resistor in parallel with each supercapacitor by taking the leak current into consideration so that the balanced of voltages is not disrupted.
