Junyi cell section equipment research and development process background:
Since 2019, with the promotion and popularization of new energy vehicles, people have also put forward more and more demands for new energy vehicles, such as longer cruising range and faster charging. Under this background, many power battery companies have disclosed about the layout of long batteries. The new energy vehicle market continues to increase, and the requirements for power batteries are also increasing. The battery cell production process is moving towards the "stacked era", and long batteries will have a wide range of market application requirements, the market space of the lamination machine will also increase rapidly. Specifically, lithium-ion equipment is divided into front-end equipment, middle-end equipment and rear-end equipment according to the battery production and manufacturing process, of which the value of middle-end equipment is about 35%, and the winding/lamination machine is the core of the middle-end equipment, with the value accounting for about 60-70%. With a value ratio of 60%, it is estimated that the market size of China's lamination machine/winding machine will reach 24.9 billion billion yuan in 2025.
Junyi is optimistic about this trend and has been laying out laminates since 2019.
The research and development of lamination machine is not simple. First of all, the technical difficulty is high. There is no unified industry standard for the process route. In addition, there are many pain points such as overhang index, work station treatment of dust after cutting, soft control linkage and compensation control, and improvement of crop movement law. Under all kinds of difficulties, the lamination machine market puts forward strict requirements on the R & D ability, technical level, capital and process understanding of the entrants. However, Junyi, based on the in-depth cooperation between deep cultivation of lithium battery equipment for more than nine years and mainstream battery factories and core component suppliers in the industry, conducted in-depth exchanges and explorations with upstream and downstream enterprises of the cutting and stacking machine at the beginning of the project development. In the scheme stage, he directly faced the pain points and difficulties of the production process, had a deep understanding of the production process, and made our cutting and stacking machine fit the existing production process, the theoretical performance has reached the advanced level of the industry.
Junyi has been laying out laminator products since 2019, which took more than a year of full-site DOE verification, while jointly developing process routes with a number of energy companies. At the end of 2021, the Z-shaped high-speed cutting and stacking all-in-one machine with high technical difficulty will be self-developed. So far, Junyi's high-speed cutting and stacking all-in-one machine products have entered the debugging and verification stage.
After the cutting and stacking all-in-one machine, our company has put the research and development team into the shell, liquid injection, sealing and other processes of the battery core to consolidate the research and development strength of the production equipment in the middle section of the battery core. At the same time, we are continuously expanding the research and development team to lay out the front section of the battery core (stirring, coating, making, ear forming) and the back section of the battery core (forming, separating, standing, static and testing), in order to build an intelligent production, become a supplier with full line delivery capability from battery cell to module pack.
