On the occasion of the birthday of the Republic, Qinghai Nord New Material Co., Ltd., located in the Dongchuan Industrial Park of Xining Economic and Technological Development Zone, has an annual production capacity of 40,000 tons of electrolytic copper foil for power battery projects, showing a scene of enthusiasm.

On the orderly construction site, the first thing that comes to mind is that the steel structure of the first floor of the project No. 1 has been completed, and dozens of silver tanks with a height of more than 10 meters have been installed. The construction workers are racing against time and preparing. The work of assembling the steel structure of the main plant of the project.

As Qinghai, which accounts for more than 80% of the national total of lithium resources, with the rapid development of strategic emerging industries such as new energy and new materials, the status of lithium industry has become increasingly prominent. The province is also building a national lithium battery industry base of 100 billion yuan. As an important “chain-in-progress” project of the lithium battery industry, Qinghai Nord’s annual production of 40,000 tons of electrolytic copper foil for power battery construction started in June last year. After completion, it will use dissolved copper and raw foil. The slitting packaging process produces electrolytic copper foil for power batteries of 6 to 12 microns.

Li Pengcheng, an executive in charge of Norwegian stock investment management, said that the construction of Qinghai Nord Lithium Electrolytic Copper Foil Project can better achieve the synergy between upstream and downstream industries, enhance the comprehensive competitiveness of Qinghai Lithium-titanium products, and give play to the advantages of Qinghai resources and optimize the industry. It is of great significance to lay out, adjust the industrial structure and improve the new material industry chain.

From the “100-day attack” campaign at the beginning of the year, after the “Golden Season Battle” and then the current “Summer and Autumn Offensive”, waves of offensives continued to attack, enabling Qinghai Noor to produce 40,000 tons of power batteries per year. The electrolytic copper foil project has made a major breakthrough.

Chen Sicheng, chairman and general manager of Qinghai Nord New Materials Co., Ltd., told the reporter that the project to produce 40,000 tons of electrolytic copper foil for power batteries will be completed in phases. The No. 1 plant, which currently covers an area of ​​14,000 square meters, is expected to be capped next month. The first phase of the 10,000-ton project will also be put into operation by the end of this year.

With the improvement of the current lithium battery industry chain in our province, the production process is the soul and core of enterprise development. Chen Sicheng introduced that they will use one of the first phase of the electrolytic copper foil project for power battery with an annual output of 40,000 tons. A more environmentally friendly and more resistant process technology that continuously reduces the heavy metal content of the product, resulting in lower chromium content in the product.

In addition to the technological breakthroughs, they also made a bold attempt in the equipment. Chen Sicheng said that they will comprehensively monitor the production process of the product through the use of the distributed control system in the entire annual production of 40,000 tons of electrolytic copper foil for power battery. Through real-time monitoring and debugging, it can not only improve product production efficiency. It can also make the product better in quality and more stable in performance.

With the continuous advancement of intelligent production, the unmanned handling in the workshop will become a reality in the electrolytic copper foil production workshop of Noah’s power battery in Qinghai. Through the application workshop unmanned handling system, combined with information acquisition technology, automation control technology, production operation management and other software technologies, the task goal of automated logistics of lithium battery copper foil is realized.

“The unmanned handling system not only makes the workshop more clean, but also saves a large part of the enterprise cost while ensuring the purification degree of the product, and this is also the first case in the domestic industry.” Chen Sicheng said.

Li Pengcheng told reporters that in order to speed up the construction of the project, we have adopted the first phase of 10,000 tons and the next investment of 15,000 tons as a private placement investment project. Qinghai lithium battery copper foil project will accelerate with quality improvement and technological innovation as the core. Construction, to achieve economic and social benefits as soon as possible.

The current development of new energy vehicles, the production of electrolytic copper foil for power batteries will be “eagle hit the sky” on the land of Qinghai, and the electrolytic copper foil project with an annual output of 40,000 tons of power batteries will become the largest in the world after completion. The electrolytic copper foil production base for power battery and the domestic large-scale high-grade electrolytic copper foil manufacturing enterprise based on the Qinghai-Tibet Plateau have injected momentum into the province’s efforts to build a national 100 billion lithium battery industry base.
