Double-layer capacitors are a type of supercapacitor. Its outstanding advantages are high power density, short charging and discharging time, long cycle life, good temperature characteristics, good reversibility, large current discharge capacity, and wide working temperature range.
Advantages of supercapacitors: 1. High power density. Widely used (AC motor; industrial LED, power; computer, display screen, etc. in the field of livelihood) 3. Release a huge amount of current in a short period. High-temperature resistance. Small size, large capacity. Long cycle life: up to 500000 cycles or more. Charging and discharging the circuit is simple.
