When the company dedicated itself to building positive materials

In 2017, Beijing Dangsheng Materials Technology Co., Ltd. achieved operating income of 2,157,906,100 yuan, an increase of 61.70 % year-on-year; The net profit of the company was 250,174,300 yuan, an increase of 151.97 % year-on-year. The company's net profit increased by 1.5 times for three consecutive years, and the scale of development and profit level were further improved. As a GEM listed company mainly engaged in research and development, production and sales of new energy materials, the rapid growth of performance in recent years has attracted extensive attention in the industry. On May 2nd, the "Chang-2018 Exploration Power Battery Future Pattern" thematic research group carried out by the Power Battery Application Branch of the China Chemical and Physical Power Power Industry Association jointly with battery China Network came to Lijianzhong Technology, and Quxiaoli, general manager, director, deputy general manager, Chenyanbin, deputy general manager of the Lithium Materials Engineering Technology Research Institute Dean Zhengchuanwei and other relevant responsible persons face to face conducted in-depth exchanges and discussions.

When Sheng Technology's predecessor was a research group of the Institute of Metallurgy of the Beijing Institute of Metallurgy and Metallurgy, it officially entered the lithium cathode material industry in 2003. The company took the lead in exporting lithium cobalt acid, lithium manganate, and multiple materials to the international high-end market. Three series of cathode materials products, The top ten lithium-electric giants in the world are company customers. In April 2010, the company successfully landed on the GEM and became the only listed company in China that focuses on lithium cathode materials.

As the technology pilot of Li-electric industry, the core competitiveness of Sheng-tech comes from strong technology foundation and untiring innovation spirit. Before 2010, China's new energy car market was in its infancy. From 2010 to 2013, the annual sales volume of new energy vehicles in China was about 10,000 vehicles. The competition in the traditional battery market was fierce, Chenyanbin, deputy general manager of Shengsheng Technology, said. "When Sheng Technology has always adhered to technological innovation as the strategic core of the company's development, it has maintained high investment in R&D, and annual R&D investment accounts for about 5 % of the operating income of the year. Battery China Network learned that more than 90 % of the doctoral and master's degrees in R&D personnel are related to materials science, electrochemistry, metallurgical engineering, chemical engineering, and powder technology. They have the characteristics of reasonable professional collocation and strong engineering ability. The main technical leaders of Shengsheng Science and Technology include senior experts such as Chenyanbin, a leader of science and technology in Beijing, Liuyafei, a special allowance expert of the State Council, and many new key players in Beijing's science and technology stars.

With the continuous adjustment of policies to support the market for new energy vehicles, changing industry patterns, declining subsidies and the return of the industry to the market, the new subsidy policy was further tightened in 2018, raising the threshold of subsidies for the length of life and battery energy density. The trend of multi-element materials, especially high-nickel multivariate materials, has become the mainstream positive material system of automotive power cells.

When Sheng Technology has been deeply engaged in the field of multiplex materials for many years, the company's high-quality high-nickel multiplex materials developed and produced by the company have been widely recognized and favored by customers. Old customers stick to the factory, and new domestic customers come to place orders. The company's dynamic multiplex materials sales have continued to increase significantly. For two consecutive years, the company's diversified materials export volume ranks first in the industry. The NCM523 has been launched in the market for three years. At present, only this product has shipped more than 1,000 tons per month. The NCM622, a high-power nickel multivariate material, was first mass-produced in China in 2014. It has now been used in large quantities for high-end electric vehicles at home and abroad. In 2017, the NCM622 has been upgraded to the second generation and introduced to the market. The NCM811, a high nickel multivariate material, has been put into production in bulk, and the technical index is at the leading level in China. The product has a good market application prospect.

In the field of energy storage lithium, when Sheng Technology made use of its solid product technical strength, keen market insight and high-quality customer channels, it became the first domestic company to successfully apply diversified materials to the international high-end energy storage market in 2016, opening up the international core customer supply chain. Product sales have increased significantly.

For the digital consumer electronics field, although it is a familiar "old battlefield", when Sheng Technology has always played the role of technology pilot, focusing on the middle and high-end markets, timely elimination of old products, development of new products, and successful introduction of strategic-grade products in 2017. To achieve the stable supply of lithium Gaodianya in high-end small applications, the market share of high-magnification products in domesticspecial models, drones and other markets reached more than 70 %. At the same time, the company firmly grasp the high price of lithium cobalt acid market situation, timely introduction of high rate of multiple materials into the small rate market, provide customers with a combination of technical advantages and cost advantages of solutions, broaden the application of multiple materials.

Referring to the company's technical advantages in the positive material industry, Chenyanbin confidently introduced two differences. One is that the actual operation of the production line is very different. He believes that although the industry says that the degree of automation is high, the actual operation effect is different. While the company has been focusing on research and development, production and sales of positive materials, and has accumulated many years of technical and practical experience in the industry, the company has taken the lead in independently designing and establishing the first domestic automatic production line with large production capacity and full containment. And grasp the technical rhythm and market rhythm to gradually expand production capacity, ensure the technological leadership of new production capacity. The second is that the preparation process is very different. He believes that each of the core equipment, coating and other processes are different, and the product performance made is very different. This is the company's core technology. Chenyanbin said that as the first domestic lithium-positive materials industry national enterprise technology center is constantly playing a technology leading demonstration role, while paying attention to their own intellectual property protection. So far, the company has participated in the drafting and formulation of a total of 14 national and industry standards such as "Lithium Cobalt", "Lithium Nickel Cobalganate", "Lithium Titrate", "Lithium-rich Mang-based" and "Lithium Iron Phosphate", and has applied for patents for 130 items of lithium electric plates. In the domestic lithium cathode material industry ranked first.

The research group conducted in-depth exchanges with the relevant personnel of Dangsheng Technology on the development trends of the lithium industry, the improvement of battery energy density, the company's production process, and the development of strategic new products. The company continuously optimized the R&D system and refined R&D functions, established the "Lithium Electric Material Research Institute" to be responsible for the basic research and new product development of lithium electric materials, and established the "Lithium Electric Material Engineering Technology Research Institute" to be responsible for the development of mass production technology and process equipment technology. And the transformation of technological achievements. The two research institutes collaborate with each other and have remarkable results. The company has established a specialized R&D personnel technical rank sequence, and set up a special project reward method to form an effective R&D incentive assessment system.

The person in charge of the research activities, the Secretary-General of the Power Battery Application Branch, the CEO of Battery China Network, Zhangyu, the standardization work department of the Power Battery Application Branch, and the director of the industry research department Zhou Bo participated in the research and discussion.

The research activities are mainly supported by Guangzhou Dongshi Chuangzhan Energy Materials Co., Ltd..
