As of February 25, the cumulative production of T98 series lithium battery separator material by the No. 2 Polyolefins Department of Dushanzi Petrochemical Company exceeded 7,000 tons, an increase of more than five times year-on-year. The Party Branch of the No. 2 Polyolefins Department of Dushanzi Petrochemical has implemented a "Party Building + Project" model, fully leveraging the political and organizational advantages of the Party to create a "red engine" for boosting production in the new year, driving high-end products such as the T98 series lithium battery separator material and polyolefin elastomer (POE) to achieve a "good start" in sales and production.

From a production perspective, this achievement is underpinned by a series of well-organized and efficient operations. The polypropylene unit of the No. 2 Polyolefins Department of Dushanzi Petrochemical Company ensures a steady supply for the production of the T98 series lithium battery separator material through stable operation. Since August 2023, when the polypropylene unit achieved stable mass production of the T98D product, the unit has continuously optimized its operations. Technical personnel closely monitor every step of the production process, from the input of raw materials, precise control of reaction conditions, to the output of the product, all of which are strictly controlled. For example, in the selection of raw materials, high-standard polypropylene raw materials are carefully chosen to ensure that the product has excellent chemical stability and mechanical properties; during the reaction process, key parameters such as temperature and pressure are monitored and adjusted in real time to ensure the reaction proceeds as expected, thereby guaranteeing the stability and consistency of the product quality.

Technology research and development played a core role in achieving this result. Relying on a 70,000 tons/year loop reactor polypropylene unit, Dushanzi Petrochemical Company has been exploring relentlessly for eight years. During the R&D process, the team faced numerous technical challenges, such as how to reduce the ash content of the product, precisely control the melt index, and improve the overall performance of the product. They actively tackled these issues, delving into the characteristics of the materials, continuously trying new formulations and production methods, and ultimately successfully developed the T98 series products. In 2023, the company's implementation of a new material development adaptability improvement project was significantly effective, further enhancing the quality and output of the lithium battery separator material. Through the upgrade and transformation of the unit, the production process became more refined, better meeting the high precision requirements of the T98 series products, laying a solid foundation for the substantial increase in production.

The growth in market demand also provided a broad space for the production of the T98 series lithium battery separator material. With the rapid development of the new energy vehicle industry and the swift rise of the energy storage market, the demand for lithium batteries has shown explosive growth. As one of the core materials for lithium batteries, the demand for lithium battery separators has also risen accordingly. The T98 series products, with their outstanding performance, such as excellent mechanical properties that prevent the separator from breaking during production and use, good chemical stability that maintains stability in complex battery chemical environments, and excellent electrical insulation properties that effectively prevent battery short circuits, can better meet the application requirements of end products, thus receiving widespread favor in the market. Many well-known domestic companies have included it in their regular bulk procurement lists, and the strong pull of market demand has prompted the No. 2 Polyolefins Department of Dushanzi Petrochemical Company to continuously expand its production scale to meet market supply.

The cumulative production of T98 series lithium battery separator material by the No. 2 Polyolefins Department of Dushanzi Petrochemical Company exceeding 7,000 tons and the significant year-on-year growth not only reflects its outstanding achievements in production capacity and technology research and development but also indicates the robust demand for high-quality lithium battery separator materials in the context of the booming new energy industry. In the future, with continuous technological advancements and ongoing market
