Supercapacitors ignite new highlights of energy storage

At present, China's supercapacitors are still in the growth and initial stage in many application fields. With the deepening of application development, China's supercapacitors will become a new bright spot in the field of chemical power sources.

The market size of supercapacitors for 　　transportation accounts for a large proportion. At the same time, the market size of supercapacitors for industrial use and new energy is also showing rapid growth.

　　In 2018, super capacitors were included in the national special support key projects and selected as key products of emerging industries. The Ministry of Industry and Information Technology, the National Development and Reform Commission, and the Ministry of Science and Technology have issued a series of special policies to clearly support the field of supercapacitors and new materials, which indicates that the supercapacitor industry has ushered in good development opportunities and indicates future growth prospects.

　　As the core basic components, supercapacitors play an increasingly important role in accelerating economic development and serving the society and people's livelihood. Not long ago, at the Supercapacitor Technology and Industry International Forum and Industry Annual Conference held in Beihai City, Guangxi, Yang Yusheng, an academician of the Chinese Academy of Engineering, pointed out, "There are many types of energy storage devices, each with its own characteristics. It is necessary to give full play to the advantages of supercapacitors and continue to develop It is difficult for other energy storage devices to compete in the application field. Improving the specific energy of capacitors is the dream of our supercapacitor field.” In order to further improve the volumetric energy density of electric double-layer capacitors , it provides useful ideas and is worthy of industrialization exploration. At the same time, many companies are working hard on the application of the fourth type of supercapacitor, the battery-type capacitor, advocated by the China Supercapacitor Industry Alliance. The Ministry of Industry and Information Technology also attaches great importance to the new field of super capacitors and has given strong support. The China Super Capacitor Industry Alliance is actively formulating relevant standards, which are very correct development directions.　

New bright spot industry

　　According to Bi Kaichun, inspector of the Science and Technology Department of the Ministry of Industry and Information Technology, in recent years, with the acceleration of my country's implementation of the strategy of manufacturing a strong country and a network power, and the in-depth promotion of major projects such as manufacturing innovation centers, intelligent manufacturing, and green manufacturing, new technologies and new industries , new formats and new models are emerging. Supercapacitors with high energy, low cost, energy saving and environmental protection as the main features have been successfully developed and entered the market, which strongly supports the rapid development of emerging industries such as new energy vehicles and advanced rail transit equipment, and leads the optimization and upgrading of traditional industries to achieve high-quality development. At the same time, with the iterative innovation of new technologies, the market expects supercapacitors to have larger capacitance, higher energy, wider operating range and longer service life, which also ushered in the development of the supercapacitor industry. precious opportunity.

　　Supercapacitors are included in the national special support key projects and selected as key products in emerging industries. The Ministry of Industry and Information Technology, the National Development and Reform Commission, and the Ministry of Science and Technology have issued a series of special policies to clearly support the field of supercapacitors and new materials, which indicates that the supercapacitor industry has ushered in good development opportunities and indicates future growth prospects.

　　At present, my country's supercapacitors are basically still in the growth and initial stage in many application fields. It is believed that in the near future, with the continuous deepening of application development, my country's supercapacitors will become a new bright spot in the field of chemical power sources.　

Insufficient investment in R&D innovation

　　As an important part of the national strategic emerging industry, supercapacitors still have many application markets to be developed. To this end, government departments such as the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the National Development and Reform Commission, and the National Energy Administration have formulated a series of strategic plans. Generally speaking, they mainly support the development of supercapacitors from three major directions. One is the construction of the research platform. For example, the construction of a national engineering technology research and development center, a national industrial innovation center, and a national engineering technology research and development center. The second is the support of special major projects. The third is to pilot and demonstrate policies to support the application and development of supercapacitors. Judging from the application of supercapacitors in my country, the market size of supercapacitors for transportation accounts for a large proportion.

　　Supercapacitors have been applied in many fields, such as wind pitch, power grid, military industry, various electric vehicles, high-speed trains, energy recovery, etc. It can be said that supercapacitors rely on their own fast charging and discharging, long service life, safety and stability, etc. Advantages, huge potential for future development. However, there are also some problems that need to be solved in the development process of the supercapacitor industry. First, the supercapacitor industry is weaker than lithium batteries in terms of policy support. For example, the subsidy policy for electric vehicles, lithium-ion batteries get dividends, and the supercapacitor industry encounters resistance. Second, there is insufficient investment in R&D and innovation in the supercapacitor industry. Compared with lithium-ion batteries, the state's support for supercapacitors is far from enough.

Urgent need for collaborative innovation in the industrial chain

　　Innovate first. The development of the supercapacitor industry has a tortuous process, so technological innovation must be combined with business philosophy, sales model, and after-sales service. Second, keep up with market demand. The real demand is not put forward by the market, nor created out of thin air by scientists and entrepreneurs, but obtained by the real understanding of the market and the exploration of human nature. Therefore, the prospects for innovation are infinitely broad.

　　Let various application fields and even governments at all levels understand more about supercapacitors, and strengthen the integration and cooperation of the mid- and downstream industry chains. It is necessary to strengthen the research on application development, expand the application from the application technology and the service model, and especially promote the model to expand and innovate. It is necessary to strengthen the coordination and cooperation of upstream and midstream enterprises in the whole chain. Promote the localization and replacement of key carbon materials and reduce the production cost of capacitor monomers. It is necessary to develop new materials and new systems for supercapacitors. Combining quasi-capacitors to develop supercapacitors with high specific energy, and actively expand applications.
