Advantages of super capacitor battery
Super capacitor battery is a new type of high-power power battery made by mixing super capacitor and lithium ion battery; one of its electrodes is activated carbon electrode of super capacitor, and one electrode is lithium ion battery electrode! He has the following advantages:
2. The power that can be released instantly is nearly ten times higher than that of ordinary batteries, and it will not be damaged.
3. The charge and discharge cycle life is more than 30000-100,000 times, which is one of the biggest advantages. Traditional batteries can only be charged and discharged hundreds of times.
4. Can be used normally in an ambient temperature of 40 to 60 degrees, the performance of traditional batteries will be greatly reduced at low temperatures.
5. With super charge retention ability, the leakage is very small, the traditional battery needs to be charged frequently to maintain the state.
6. Charging is fast, its speed is dozens of times faster than ordinary batteries, and it can fully charge the power required by a car in a few minutes.
7. It will not cause pollution to the environment itself, and it is truly maintenance-free, while traditional batteries are still polluted.
