Supercapacitors and lithium-ion batteries are familiar electrical energy devices. The electric cars, mobile phones, notebooks, tablets, etc. that we often use all use lithium-ion batteries. You may be a little unfamiliar with supercapacitors. In fact, the performance of supercapacitors and lithium-ion batteries are complementary. Lithium-ion batteries convert electrical energy into chemical energy, and when used, chemical energy is converted into electrical energy.
Therefore, the characteristics of lithium-ion batteries are high energy density and long battery life. Its shortcomings are slower charging speed and shorter cycle time. After a period of use, the performance decays faster, and the performance becomes worse at low temperatures. This results in slower charging speed and reduced capacitance. Compared with lithium batteries, supercapacitors are a sprint champion. Supercapacitors store electrical energy in the device through an electric double layer in the form of electric charge, and are not involved in the conversion of energy like lithium-ion batteries.
Therefore, the reversibility of the supercapacitor is better, and the response is faster. Although the energy of supercapacitors is not high, the storage capacity per unit volume is lower than that of lithium-ion batteries, but they can be quickly charged within one minute. And has a long cycle life.
All in all, supercapacitors have the characteristics of high power density, good low temperature performance, fast charging, and long use time. This is why supercapacitors are called sprint champion in the capacitor industry. Hopefully this article can help you better understand supercapacitors.
