Supercapacitors are bringing new materials and may have far-reaching consequences in the future

With the increasing demand for energy and the reduction of fossil fuels, it is of great importance to use renewable energy for power generation. Moreover, energy storage is as important as energy production for industrial progress and human well-being.

Supercapacitor is an attractive electrochemical energy storage system with the advantages of low price, relatively high energy density, high specific capacitance, high capacitance retention rate and renewability.

As an electrode material in various energy storage technologies, organic materials have received much attention in recent years. Conjugated polymers (pi-CPs) are attractive because of their many advantages, such as good conductivity, cost-effectiveness, light weight and environmental protection. Among them, using pi-CPs as the electrode material of multifunctional energy storage system can greatly promote the rapid development and innovation of electrode materials.

Chemical oxidation polymerization is a two-electron exchange technology that requires the use of oxidants to oxidize monomers. Electropolymerization is the most advantageous synthetic method after oxidative polymerization. Polymerization occurs at the working electrodes when an external voltage is applied. In most cases, these synthesizations are carried out in a glove-type operating box.

Super capacitor is generally referred to as double layer capacitance. Double layer capacitance is a kind of super capacitor and a new type of energy storage device.

The double layer capacitance is between the battery and the capacitance, and its enormous capacity can be fully used as a battery.

Double-layer capacitors are widely used. As the power balance power supply of the lifting unit, it can provide the power with extra large current. As a starting power supply for vehicles, the starting efficiency and reliability are higher than traditional batteries, which can completely or partially replace the traditional batteries. It can be used as traction energy for vehicles to produce electric vehicles, replace traditional internal combustion engines, and transform existing trolleys. Military use ensures the smooth start of tanks, armored vehicles and other combat vehicles (especially in the cold winter), as pulse energy for laser weapons. It can also be used to store energy for other electromechanical devices.
