What are the advantages and disadvantages of supercapacitors?

The research and development of supercapacitors has always been shrouded in the shadow of batteries (mainly nickel hydrogen batteries and lithium batteries). The development of nickel hydrogen batteries and lithium batteries can receive huge financial support from governments and major investors, greatly promote technological exchanges, and make it easier to focus on the world's attention. In contrast, supercapacitors are difficult to obtain strong financial support, which greatly restricts the progress and development of technology. In addition, the high cost and low energy density of supercapacitors are in stark contrast to lithium batteries, which make them neglected in many fields but always replaced by batteries in practical applications. However, supercapacitors have made breakthroughs in technology and will have a great driving force for the development of the new bear source industry. The advantages and disadvantages of supercapacitors determine their future development.4.2V4.2AH1.jpg

Advantages: (1) Fast charging speed. Charging for 10 seconds to 10 minutes can reach over 95% of its rated capacity;

(2) Long cycle life, with deep charging and discharging cycles up to 1-500000 times, without any "memory effect"

(3) High current discharge capability, high energy conversion efficiency, low process loss, high current energy cycling efficiency ≥ 90%;

(4) High power density, up to 300W/KG~5000W/KG, equivalent to 5-10 times that of a battery;

(5) The composition, production, use, storage, and dismantling process of the product's raw materials are pollution-free, making it an ideal green and environmentally friendly power source;

(6) The charging and discharging circuit is simple, without the need for charging circuits like batteries, with a high safety factor and maintenance free long-term use;

(7) Excellent ultra-low temperature characteristics, with a wide temperature range of -40 ° C to+70 ° C;

(8) Convenient detection, the remaining electrical scene can be directly read out;

(9) The capacity range is usually 0.1F-1000F.

Disadvantages: (1) Improper use can cause electrolyte leakage and other phenomena;

(2) Compared with aluminum electrolytic capacitors, it has a higher internal resistance and therefore cannot be used in AC circuits;
