Supercapacitors are different from traditional batteries in that they can quickly store a large amount of energy and release it quickly. For example, when a train enters a station, the supercapacitor can store the energy generated by braking, and then provide it to the train when the train needs a lot of energy to start. What are the characteristics of supercapacitors compared with batteries? Let's read this article to learn!
The characteristics of supercapacitors compared with batteries:
1) Ultra-low series equivalent resistance (ESR), power density is more than tens of times that of lithium-ion batteries, suitable for high current discharge (a 4.7F capacitor can release an instantaneous current of more than 18A).
2) Ultra-long service life, charging and discharging more than 500,000 times, which is 500 times that of Li-Ion batteries, and 1000 times that of Ni-MH and Ni-Cd batteries. If supercapacitors are charged and discharged 20 times a day, then they can be used for 68 years.
3) It can be charged with a large current, the charging and discharging time is short, the requirements for the charging circuit are simple, and there is no memory effect.
4) Maintenance-free and can be sealed.
5) The temperature range is wide -40℃～+70℃, the general battery is -20℃～60℃.
6) Super capacitors can be connected in series to form a super capacitor module, which can withstand voltage and store higher capacity.
The above content is the characteristics of supercapacitors compared with batteries. Hopefully this article will be helpful to everyone.
