According to the electrolyte of the supercapacitor, it can be divided into the following two types:
The maximum available voltage of a supercapacitor is determined by the decomposition voltage of the electrolyte. The electrolyte may be an aqueous solution (such as a strong acid or a strong alkali solution) or an organic solution (such as a protic solvent solution of a salt). High-capacity and high specific power can be obtained by using an aqueous solution system (since the electrolyte resistance of the aqueous solution is lower than that of the non-aqueous electrolyte, the conductance of the aqueous solution is 10 - 1~10 - 2 S·cm -1 , and the conductivity of the aqueous solution is 10 - 3~10. - 4S·cm - 1) High voltage can be obtained by using an organic solution system (because the electrolyte decomposition voltage is higher than that of the aqueous solution, the decomposition voltage of the organic solution is about 3.5 V, and the aqueous solution is 1.2 V), so that a high specific energy can be obtained. . 


The prospect of supercapacitors

At present, the research focus of supercapacitors in foreign countries (especially the United States and Japan) mainly focuses on how to improve the energy storage density of supercapacitors to meet the application of electric vehicles. The research content involves the research and development of new materials and the improvement of production process methods. Domestic research on supercapacitors has just started. At present, only a few companies can industrially produce activated carbon supercapacitors, and much work needs to be done.

Although supercapacitors show great vitality in applications, it should be noted that current supercapacitors still have a certain gap in terms of electrical energy storage compared with batteries. Therefore, how to increase the energy storage density per unit volume is the current supercapacitor. A research focus and difficulty in the field.

It should be said that the improvement of the fabrication process and technology is an effective way to improve the ability of supercapacitors to store electrical energy, including "hybrid" supercapacitor technology. But in the long run, finding new electrode active materials is fundamental, but at the same time it is also difficult. The realization of ultra-capacitor lighter and more powerful power supply must rely on the development and application of some high-tech, such as nanotechnology. Only in this way, the prospect of supercapacitors will become brighter and brighter.
