Q: What are the characteristics of super capacitors and batteries respectively?
A: The super capacitor can be charged to any electricity level within its rated voltage range and can be completely discharged. The battery is limited by its own chemical reaction to work in a narrow voltage range, and it may cause permanent damage if over-discharged. Supercapacitors can store more energy than traditional capacitors of comparable volume, and batteries can store more energy than supercapacitors of comparable volume. In some applications where power determines the size of energy storage devices, supercapacitors are a better way. Supercapacitors can repeatedly transmit energy pulses without any adverse effects. On the contrary, if the battery repeatedly transmits high-power pulses, its life will be greatly reduced. Supercapacitors can be charged quickly but batteries can be damaged if they are charged quickly. Supercapacitors can be cycled hundreds of thousands of times, while battery life is only a few hundred cycles.
Q: What is the life span of a supercapacitor?
A: The withstand voltage of supercapacitors is relatively low, usually only 2.5V, and the allowable surge voltage is 2.7V. Therefore, for a single supercapacitor, the maximum output voltage of the charger cannot exceed 2.7V. As long as the working voltage of the supercapacitor is at a safe voltage, the service life of supercapacitors can be very long, and the number of charging and discharging cycles can reach 100,000 to 500,000 times.
