On April 12, 2016, the Ministry of Industry and Information Technology issued the Implementation Plan of 2016 Special Action to Strengthen the Industrial Foundation, which listed supercapacitors as the key support. As soon as this news came out, many super capacitor concept stocks were strongly recommended by major securities companies.
As an important part of the national strategic emerging industry, supercapacitors are related to new information, new energy cars, new energy, energy conservation and environmental protection, new urban public transport and other key areas, and there are many potential shopping malls waiting to be developed. The government has formulated a series of strategic planning in terms of macro policies.
It is different from the traditional chemical power supply, which is Farad capacitor The power supply with special performance between the battery and the battery mainly relies on double electric layers and oxidation recovery pseudocapacitance charge to store electric energy. However, chemical reaction does not occur in the process of energy storage. This process of energy storage is reversible, and it is precisely because this Farad capacitor can be recharged and discharged hundreds of thousands of times.
Supercapacitor battery is a kind of power supply element with special functions between traditional capacitors and batteries. Its basic principle is the same as other types of electric double layer capacitors. Both of them use the double layer structure composed of activated carbon porous electrodes and electrolytes to obtain super capacity. During this period, no chemical reaction occurs, so it is classified as a physical battery. from Super capacitor module It can be seen from its function that the broad penetration of various categories in the future has huge advantages, which may extend the infinite possibility in space.
Most of the supercapacitors for new energy cars are high-capacity modules, which are widely used in the wind turbine pitch system in the wind power field. According to the calculation of the Energy Bureau, in 2015, the new installed capacity of the national wind power industry was 32.97 million kilowatts, and the cumulative grid connected installed capacity reached 129 million kilowatts, accounting for 8.6% of the total installed power generation capacity. The strong growth momentum together means that there is a lot of demand for fan pitch system, and also means that there is a wide market for supercapacitors.
In the supercapacitor industry chain, the raw materials of the production link are mainly positive and negative electrodes/electrolyte and barriers. among Super capacitor manufacturer Most of the electrode activity data are activated carbon, and its industrialization skills are mainly in the hands of western developed countries. The skills of estrangement are in the hands of Japanese enterprises. In terms of electrolyte, there is no technical bottleneck in China. Its manufacturing process: batching → slurry mixing → electrode making → cutting → assembly → liquid injection → activation → detection → packaging. The whole process has high skill content and high access threshold.
As an energy storage system with large energy storage, fast charging and discharging speed, wide operating temperature range, safe and reliable operation, and no need for maintenance, supercapacitor will gradually replace batteries with the development of supercapacitor technology, and its application fields will continue to expand, which will promote technological progress and achieve greater economic and social benefits.
