Top 5 supercapacitor energy storage companies in China

Supercapacitors are smaller in volume and larger in capacity than ordinary capacitors. Because the ordinary capacitance is composed of two electric plates with an insulating layer between them, the capacity depends on the area of the electric plate.Ordinary capacitors are rolled by electric plates, thus increasing the area.

The electrode of supercapacitor is made of porous carbon. Because of the super many pores, the contact area of electrolyte is super large, which can reach 2000 square meters/g. So very small volume can reach Ferrari class capacitance value.

Super capacitor has large capacity, so it can be used as power supply directly because of its short charging time and long power consumption time. Moreover, if the super capacitor is used for power supply, over charging and discharging will not have any impact on its life.

But its disadvantage is also obvious, because there is electrolyte in it, which is easy to leak. The internal resistance is also relatively large. Do not use for AC circuits. This article will introduce the top 5 supercapacitor energy storage companies in China in 2022.

Current development of supercapacitor energy storage

In recent years, as the application scenarios of super capacitor downstream in new energy, rail transit, industry and other fields have been continuously explored, the industry space has been further expanded, and the industry has returned to the high-speed growth period.

It is expected that under the background of rapid development of new energy in the future, downstream demand for wind power pitching, over capacity public transport, grid side energy storage and other technologies will grow rapidly, and the over capacity market will still maintain a rapid growth rate.

With the development of energy storage technology in the direction of hybrid energy storage mode, high conversion efficiency, high energy density, low-cost application and environment-friendly, the combination of photovoltaic power generation and energy storage technology will greatly improve the energy utilization and economy of photovoltaic power generation system.

Supercapacitors have simple structure, strong charging and discharging capacity. The advantages of economy and environmental protection provide an important technical guarantee for achieving carbon peak and carbon neutralization, and the future is bright.
