"You don't look at this 8-meter wide battery separator is very easy to pull out, in fact, it is very difficult to keep the thickness of the entire width consistent, we have our own 'unique secret', to achieve this world-leading product 'made in Nantong Development Zone'. On the 9th, standing in front of the fifth-generation super wet normal line of Xingyuan Material (Nantong) New Material Technology Co., Ltd., pointing to the white diaphragm products continuously pulled out of the machine, Xu Liqiang, general manager of the company, said proudly.
Xingyuan Material Nantong Company settled in Nantong Development Zone on June 18, 2021 and is a wholly-owned subsidiary of Shenzhen Xingyuan Material Technology Co., Ltd., a listed company. The project broke ground in November 2021, the first phase of the coating production line was put into operation in September 2022, and in December of the same year, the wet production line was put into operation, becoming the first automated and intelligent green separator factory in the history of the lithium-ion separator manufacturing industry to start construction within one year, build within one year, put into production within one year, and have the first construction speed.
"With the strong support of Nantong Development Zone, after more than a year of production, our current production capacity is completely full, and the annual output of battery separators is expected to reach 2 billion square meters this year. Xu Liqiang said that in addition to the strong support of Nantong Development Zone, Nantong Xingyuan can achieve such impressive development results, and it is inseparable from the fifth-generation super wet production line independently developed by Xingyuan Materials.
"To be honest, in the field of battery separators, homogenization competition is still very fierce, to occupy a larger market share, we must increase research and development, with new processes and new technologies to produce more high-end products. Adhering to the brand concept of "leading technology and diaphragm expert", through the unremitting research and development of a professional team of more than 200 people at Xingyuan Material Headquarters, on August 18 last year, the fifth-generation super wet normal line invested and built by Nantong Xingyuan was officially released, which is currently the most modern product production line in the world.
According to reports, through the integration of digital technology, the production line has the characteristics of "three highs and one low", that is, high efficiency, high quality, high intelligence and ultra-low energy consumption, with a single-line production capacity of 250 million square meters, which is more than 2 times higher than the single-line production capacity of the fourth-generation wet normal line, and will continue to provide products and services for domestic and foreign leading enterprises in the future. At the same time, the products have high heat resistance and high flame retardancy, which will further ensure the safety of batteries.
With these new technologies and new products, Xingyuan Materials has opened up more overseas markets and provided products for many automobile manufacturers around the world for high-end applications. "After more than a year of operation, it has delivered remarkable results, and it has also allowed Xingyuan Material Headquarters to see the scientific and technological innovation environment and service capabilities of Nantong Development Zone.
"At present, the headquarters is ready to put part of the R&D functions in Nantong to actively explore and develop more cutting-edge technologies. According to Xu Liqiang, the company has set up a R&D center in East China in Nantong, which will soon start operation. "Many of our customers are in the Yangtze River Delta region, and the layout of R&D teams here can interact with the market more efficiently and better meet the R&D requirements put forward by cooperative customers. ”
On the other hand, in Xu Liqiang's view, Nantong Development Zone and its surroundings have a good scientific and technological innovation platform, which can provide more "external brains" for enterprise research and development. This year, Nantong Xingyuan has established in-depth industry-university-research cooperation with the Institute of Materials Engineering Technology of Nantong Nanjing University to jointly build a technology platform, increase R&D investment, and further catch up with and surpass the world-class level.
