Capacitors have different form factors and different forms of performance. Currently, there are cylindrical supercapacitors , button-type supercapacitors, and horn-type supercapacitors.
Different types of trials have different scopes and meet the needs of various fields, and they are still targeted.
A supercapacitor is a new type of energy storage device between a conventional capacitor and a rechargeable battery, which can have a capacity of several hundred to several thousand. Compared with traditional capacitors, it has larger capacity, specific energy or capacity density, wider operating temperature range and extremely long service life. Compared with batteries, it has higher specific power and environmental protection. No pollution.
A supercapacitor is a new type of component that stores energy through a two-layer interface formed between an electrode and an electrolyte. When the electrode is in contact with the electrolyte, due to the effects of Coulomb force, intermolecular force and interatomic force, the solid-liquid interface exhibits a stable double-layer charge with opposite sign, which is called an interface double layer. The electric double layer supercapacitor was regarded as two inactive porous plates suspended in an electrolyte, and the voltage was applied to two plates. The potential applied to the positive electrode plate attracts negative ions in the electrolyte, and the negative electrode plate attracts positive ions, thereby forming an electric double layer capacitor on the surface of the two electrodes. The electric double layer capacitor can be classified into a carbon electrode double layer super capacitor, a metal oxide electrode super capacitor, and an organic polymer electrode super capacitor depending on the electrode material.
The appearance of capacitors has changed the storage of electricity and realized the reversibility of electricity. This is in line with today's development requirements. It can be used at will, and it is very convenient. In the future, the shape of the capacitor will definitely change differently, but it has been The constant is the performance of its charge discharge.
