Super capacitor The new energy storage industry's joy and worry

A bus can be fully charged in one minute, and can travel for 6 kilometers after each charge. As a kind of energy storage device with special properties between traditional capacitors and batteries, it has short charge and discharge times and cycle life. The excellent characteristics of long, repeated charge and discharge hundreds of thousands of times subvert the intrinsic impression of energy storage equipment in energy-related fields. However, when supercapacitors expanded their industrial maps, they were met with mixed weather and were mixed.

Make good use of their own advantages to connect with national development strategies. Because the electric energy storage of the electric double layer and redox pseudocapacitors is used to store energy, the supercapacitor's energy storage process is a reversible physical reaction, so the charging rate is very fast. It takes only 10 seconds to 10 minutes to reach more than 95% of the rated capacity. Can be repeatedly charged and discharged hundreds of thousands of times. In addition to the constitution, production, use, storage, and dismantling of raw materials, there is no pollution, and supercapacitors can be regarded as ideal green power supplies. In the country's vigorous advocacy for the construction of a "two-type" society and the development of a green, energy-saving and environmentally friendly industry, the industrialization, application and promotion of corresponding scientific research results, and the advantages of taking advantage of the weather, will take advantage of the trend.

At the same time, China’s strategic planning and active advocacy of new energy technologies has also become a booster for the rapid development of supercapacitors. The inherent characteristics of some new energy sources, such as solar energy, wind energy, and tidal energy, determine that their power generation methods are often heterogeneous, and the power output can easily change. This requires the use of a buffer to store energy, and the supercapacitor becomes. Take the application of Superstar Technology's super-capacitor in smart microgrid as an example. Micro-grid scale is small, self-adjusting ability is weak, load fluctuations and grid operation failures will have a great impact on it. In the microgrid, a hybrid energy storage system of a supercapacitor and a battery is provided to store excess energy when the load is low, and the stored peak energy is fed back to the microgrid to provide assistance in regulating the power of the microgrid and to effectively solve the problem of the microgrid voltage. Drop, voltage drop and other issues, improve microgrid power quality.
