What's the difference between a supercapacitor and a battery? In terms of performance

The battery charges slowly, and the supercapacitor charges quickly; The discharge power of the battery is small, and the super capacitor is large; The battery life is short, the super capacitor can be charged and discharged for 500,000 times, and the service life is long; The charging efficiency of the battery is low, and it can't absorb weak current, while the super capacitor can, so the charging efficiency is low; Battery charging and discharging is a chemical process, which will cause environmental pollution. The charging and discharging of supercapacitors is a physical process, which is environmentally friendly. The battery is difficult to charge and discharge at low temperature, and the temperature range of supercapacitors is very wide, from -40 degrees to 70 degrees. The storage capacity of battery is good, but the storage capacity of supercapacitor is weak.

In a word, as a new type of energy storage element, supercapacitor can make up for the shortage of battery to a great extent.

In solar energy, you can use supercapacitors instead of batteries. Some products are already in use, such as solar lawn.
