What is a supercapacitor?

"Simply put, supercapacitor is a kind of energy storage device with special performance between traditional capacitor and battery. A bus 1 minute can be fully charged, and it can travel 6 kilometers after each charge. The world's leading clean energy equipment supercapacitor made in China will bring great changes to the transportation industry. " The person in charge of Jixing Technology told the reporter that today's supercapacitors have subverted people's inherent impression of energy storage equipment because of their short charging and discharging time, long cycle life and repeated charging and discharging hundreds of thousands of times.

In 2002, Jixing Technology was founded by the research and development team of carbon nano-materials in Tsinghua University. From the initial research and development of supercapacitors based on activated carbon fiber materials to the evaluation of electric double-layer supercapacitors as national key new products, in a few years, the company has carried out a large number of basic experiments, which laid a technical foundation for subsequent product research and development, but it is still in the laboratory stage. Although with advanced technology, laboratory products have been successfully developed, but the products have not been mass-produced and lack of funds. Jixing technology is in a development dilemma, which requires both financing and operation. I want to sell products and open the market.

Energy storage industry is a technology and capital intensive industry. From laboratory research and development, small test and pilot test, all links must be invested, ranging from hundreds of thousands to millions. From the trial production of products to the expansion of equipment, and then to the establishment of standardized processes, the whole process is overwhelmed by the investment of entrepreneurial teams. Since 2007, Jixing Technology has started its marriage with capital.

Since angel investors first expounded the principle and prospect of supercapacitors, the core team of Jixing Technology embarked on a long financing journey, and then funds such as Northern Lights Venture Capital, Tiqi Venture Capital and Yingteng Jiaxiang Investment became shareholders. Industrial investors such as Black Peony Group, Yutong Bus and Shanghai Electric also laid out the supercapacitor industry through Jixing Technology. "The electrochemical industry needs time to accumulate." Chen Shengjun, chairman and CEO of the company, said that only by constantly researching, improving and opening up the market can we use this good product more. But this process is not easy, from power tools to wind power and electric vehicles, every step is difficult.

By 20 10, the team of Jixing Technology found a more intractable problem: as the company grew, there were more and more competitors. "Foreign manufacturers who disdained to compete with us found Jixing Technology and started positive competition, which made us feel unprecedented pressure." Chen Shengjun said that when Jixing Technology entered the wind power market, it was faced with the global leading enterprises in the field of supercapacitors, whose technological leadership and product stability were much higher.

How to choose? Only by establishing modern standard chemical plants can we stabilize product quality and have a basis for competition with international manufacturers. 20 10 After several comparisons, Jixing Technology chose to establish a modern production line in Changzhou, Jiangsu. "Investors are very helpful to the development of the company at different stages." Chen Shengjun said, for example, in the process of establishing a production base in Changzhou, Peony Venture Capital gave great support, not only planned the production base in Changzhou Science and Technology Park of Black Peony, but also sent professional on-site management personnel to help improve the production management system.

After hard work, the Jixing technology team also handed over satisfactory answers to investors. On 20 1 1 year, the company's products won the second prize of the National Technology Invention Award, showing its technical strength. 20 12 Jixing Technology and China South Locomotive jointly established Ningbo CRRC New Energy Technology Co., Ltd. ... Subsequently, the policy was favorable frequently, the government promulgated the subsidy policy for new energy vehicles, and the orders of new energy bus manufacturers continued to increase. CSR, Delong and Haima have all become customers of Jixing Technology. Yutong, the largest bus manufacturer in China, has also become a strategic investor in Jixing Technology. By the end of 20 15, Yutong had purchased tens of thousands of supercapacitor modules from Jixing Technology.

At the beginning of this year, Jixing Technology released a number of latest research results, among which the release of 3V ultra-electric monomer series was a few months earlier than that of foreign ultra-electric leading enterprises, making it the first enterprise in the world to realize this technology. Chen Shengjun said that Jixing Technology is the first enterprise in the supercapacitor industry to win the national technological invention award, and has invested a lot of human and financial resources to speed up technological research and development, and has formed sustained and stable cooperation with domestic and foreign first-class universities and upstream and downstream enterprises such as Tsinghua University and Japanese Institute of Materials.

Up to now, Jixing Technology has become the largest manufacturer and the most widely used enterprise of supercapacitors in China, and it is also one of the few domestic supercapacitor manufacturers and system solution providers with international quality.

Jixing technology is like a duck to water in the application field, benefiting from its continuous technological innovation ability. A few days ago, Jixing Technology established the first supercapacitor research institute in China in Changzhou, Jiangsu Province, consolidating the road of scientific and technological innovation and transformation of scientific research results, trying to compete with international giants. "For a long time, we have been focusing on performance and cost. The performance of supercapacitor products is very good. At present, the key issue is price. We are working with a large number of China enterprises to promote rapid cost reduction, which is a key development goal in the future. " Chen Shengjun said.
