Will Battery Be Replaced by Super Capacitor

Oct. 13, 2021

The development of science and technology has also promoted the development of capacitors. Take super capacitors for example, they are increasingly used in notebook computers, cameras, smart phones or electric vehicles. Supercapacitors are different from traditional batteries in that they store large amount of energy quickly and release them quickly. For example, when a train enters a station to brake, the supercapacitor can store the energy generated by braking and provide it to the train when the train needs a lot of energy to start. Will batteries be replaced by super capacitors in the future?

Supercapacitors are moving in the direction of replacing batteries. Compared with lithium-ion and other battery technologies, supercapacitors have advantages in the aspects such as safety, fast charging and size, and at the same time contribute to complex battery management systems for various applications such as automobiles, power grids, and IT.

However, the battery will not be replaced by a super capacitor. Both of them have advantages. For the selection, we must choose the appropriate super capacitor or battery according to the actual situation of the circuit. In some cases that require high-power discharge and higher output energy, you can use supercapacitors and batteries in combination to give full play to the advantages of both.

Will Battery Be Replaced by Super Capacitor

Supercapacitors and batteries are energy storage components, the difference is:

① The energy storage process of supercapacitors is a physical process, and battery energy storage is a chemical reaction process;

②The working temperature of the super capacitor is wider than that of the battery, -40 to 65 Celsius degrees;

③Due to the physical process of supercapacitor charging, the service life is longer. Generally, the number of charge and discharge times is more than 500,000 times, and the number of battery charge and discharge times is much less. Lead-acid batteries are 500 times, and lithium batteries are 1000-1500 times. Different types of batteries have different number of charge and discharge times;

④The power characteristics of supercapacitors are better than that of batteries, and they can be charged and discharged quickly with high current. The energy density of batteries is higher than that of supercapacitors, and the battery can store more energy under the same volume;

Whether it is a super capacitor or a battery, we must understand its advantages before using it, which can help us to better use it. Hopefully the content of this article will be helpful to everyone.
