CR1212 battery.Ningbo CRRC New Energy: Supercapacitor technology leads the world

　　Within 7 years of settling in Yinzhou, the industrial scale started from scratch, and now the annual output value exceeds 300 million yuan; the "supercapacitor" series products have broken the foreign technology monopoly and led the world, demonstrating the level of "I have what others have, and I have excellence when others have". Ruan Dianbo, chief engineer of Ningbo CRRC New Energy Technology Co., Ltd. and chief technical expert of CRRC, said with a smile that the company's ability to win the China Patent Gold Award was a natural result of "the right time, the right place and the right people". On December 13, 2017, Ruan Dianbo took home the China Patent Gold Award from Beijing on behalf of the company. The heavy trophy symbolizes the highest honor in the field of intellectual property rights in my country. The criteria for participating in the China Patent Gold Award not only emphasize the patented technology level and innovation level of the project, but also focus on the actual situation of market transformation and application and social benefits, which also have extensive influence internationally. That year, there were approximately 1.382 million invention patent applications nationwide, and 420,000 invention patents were authorized. However, there were only 20 China Patent Gold Medals. Ningbo CRRC New Energy firmly grasped this small probability. Supercapacitor, a term reminiscent of science fiction movies, is one of the most efficient new energy storage devices for energy storage and energy saving. It has the advantages of both capacitors and batteries. Its energy density is much higher than traditional capacitors, and its power density is much greater than secondary batteries. It has broad application prospects in transportation, special applications, energy and other fields. However, the core preparation technology of large-capacity supercapacitors has long been monopolized by foreign countries. The "Supercapacitor Manufacturing Method", which won the China Patent Gold Award, systematically solved the common problem of low energy density of supercapacitors in three aspects: technological innovation, material innovation and process innovation, completely breaking the foreign technology blockade and improving energy density. Twice that of similar products in the world, providing the market with a more efficient, intelligent and green "power core". For this transcendence, Ningbo CRRC New Energy has been preparing for many years. In 2012, Ruan Dianbo, who has been deeply involved in the field of supercapacitors for more than 20 years, brought the technology that won the national scientific and technological achievement award to the Ningbo CRRC Industrial Base in Yinzhou. With the motivation of "must break through the foreign technology blockade", he and General Manager Fu Guansheng Together, we lead the core team to engage in project construction and new product research and development in a 30-square-meter bungalow. No matter how difficult the conditions are, they cannot stop enterprises from making steady progress. In the same year, the supercapacitor physical and chemical laboratory and new product pilot line were built, and the world's first 7,500 farad supercapacitor unit was successfully launched. This capacity far exceeded the products of the United States and South Korea at the same time. In 2013, two supercapacitor production lines representing the internationally advanced level were completed and put into production. Ningbo CRRC New Energy leads the world in identifying one new product every year. Under the premise that the volume and weight remain unchanged, the energy density of supercapacitors has increased from 7,500, 9,500, 12,000, and 17,000 to 30,000 and 60,000 farads, leaving foreign competitors further and further away time and time again. In just a few years, Ningbo CRRC New Energy has established a world-class team in Yinzhou, growing from 4 people at the beginning to more than 50 people now, including 35 masters and 9 doctors, making it the world's largest and largest team in this field. The dream team with the strongest R&D capabilities. From technology leadership to product leadership, Ningbo CRRC New Energy’s dream team and engineering technology team have realized the production of domestic supercapacitors based on the application of the invention patent "Supercapacitor Manufacturing Method" with the help of high-end equipment and advanced process means. Large-scale production, and innovative development of new hybrid supercapacitors with multiple systems such as high specific energy double-layer supercapacitors, lithium-ion capacitors, and battery capacitors have further improved system integration capabilities and product added value. At present, supercapacitors have been successfully used in the world's first supercapacitor energy storage trams and trolleybuses, as well as in emerging industrial energy-saving and special high-end equipment fields such as port machinery, mining machinery, and ships, and have been exported to Malaysia, Austria, and Macedonia. and other countries, the economic and social benefits are considerable. Yinzhou's strong atmosphere of innovation and the support of various departments at the urban and municipal levels have also created a good environment for the development of enterprises. Since 2012, a total of 175 million yuan of development support funds have been provided to Ningbo CRRC New Energy in the form of "one enterprise, one policy" from the national to the district level. Ruan Dianbo said that recently, Ningbo CRRC New Energy is promoting the construction of an innovation center. Once completed, it will play a major role in supporting the enterprise's innovation system, coordinating the industrial chain, and producing scientific research results.
