Super capacitor Battery (II)

Difference between super capacitor and ordinary battery:

1. The super capacitor can be charged to any potential within its rated voltage and can be fully discharged. The battery is limited by its own chemical reaction and works in a narrow voltage range. If it is overdisposed, it may cause permanent damage.

2. The state of charge (SOC) and voltage of a super capacitor constitute a simple function, while the state of charge of a battery includes a variety of complex scalings.

3. Super capacitors can store more energy than their equivalent conventional capacitors, and batteries can store more energy than their equivalent counterparts. In some applications where power determines the size of the energy storage device, a super capacitor is a better approach.

4. The super capacitor can repeatedly transmit energy pulses without any adverse effects. On the contrary, if the battery repeatedly transmits high power pulses, its lifetime is greatly reduced.

5. Super capacitors can be charged quickly and the battery can be quickly charged.

6. Super capacitors can be cycled hundreds of thousands of times, with only a few hundred cycles of battery life

7. Materials used in super capacitors are safe and non-toxic, while lead-acid batteries and nickel-cadmium batteries have

toxicity.

8. Normal operation can be performed over a wide range of temperatures (-40 to +70°C) and it is difficult for batteries to operate in high, especially low environments.
