Supercapacitors, also known as electrochemical capacitors or electric double layer capacitors (EDLC), is a new energy storage device between traditional capacitors and secondary batteries. It uses the electric double layer at the electrode / electrolyte interface or rapid and reversible redox reaction at the electrode interface to store energy.

Supercapacitor has high power density, which is several times higher than that of battery, and has ultra long cycle. At present, the research on activated carbon materials mainly focuses on the preparation of high-performance activated carbon materials, the service life of activated carbon electrode, high current rapid charge and discharge capacity, clean and pollution-free advantages, and is widely used in mobile communication, standby power supply Consumer electronics and power vehicles have broad application prospects and have attracted extensive attention all over the world. As the earliest electrode material used in supercapacitors, activated carbon has been the focus of research because of its low price and high electrochemical stability. The research on preparation technology is relatively few. As the core part of supercapacitor, the preparation process and material structure have a great impact on its electrochemical properties

The application of super capacitor in electric vehicle can realize the rapid charging of electric vehicle, and the charging efficiency can be effectively improved. Supercapacitor first appeared in the late 1970s. After that, it has been continuously developed and gradually applied in the field of electric vehicles. The supercapacitor is composed of a polarizable carbon electrode, a non polarizable electrode and a non-aqueous electrolyte. Its internal chemical activity includes inductive and non inductive processes, which is significantly helpful in increasing the working voltage of the battery, Super capacitor battery actually refers to super capacitor, which is just an abbreviation to describe that it can replace battery: can super capacitor replace lithium battery of mobile phone?, Because capacitors and batteries are always two components with different internal structures, they are not the same electronic components. In most cases, they have been used together. For example, the more common new energy vehicles are the combination of super capacitors and lithium batteries. Therefore, super capacitor batteries are only a name to describe the role of super capacitors.
