On September 27, Xingyuan Material issued an announcement on additional investment to European subsidiaries. The announcement stated that the company intends to invest in the wholly -owned subsidiary of Sweden's establishment of Xingyuan Material (Europe) Co., Ltd. to invest in more than 192 million yuan. equipment.

Regarding the expansion plan of the septum enterprise, Meng Xiangxu, an analyst of the lithium battery material industry of Longzhong Information Lithium Battery Materials Industry, commented on the reporter of the Securities Daily: "It mainly comes from two aspects. First, the demand for downstream power batteries has increased rapidly, driving the vigorousness of the diaphragm, which Demand; second, China, as the world's largest septum exporter, provides a broad market space for the development of the diaphragm industry. "

According to statistics from high -industry lithium batteries, the shipments of China's lithium batteries in 2021 were 7.8 billion square meters, an increase of over 100%year -on -year. From the perspective of the global market competition pattern, 73.8%of the global septum market share in 2021 concentrated in China. Cinda Securities said that global production capacity is constantly concentrated to China, and China's production capacity is concentrated in head enterprises. Domestic manufacturers are mainly enterprises such as Enjie, Xingyuan materials, and Chinese technology technology.

The leaders in the septum industry have expanded production

Chinese diaphragm manufacturers have global competitiveness. In 2021, due to the double high growth of global new energy vehicle demand and energy storage market, domestic septum shipments have increased significantly.

The annual report of 2021 shows that Enjie is currently the largest lithium battery septum supplier in the world, with shipments of more than 3 billion square meters last year; Xingyuan Materials shipments were 1.22 billion square meters, an increase of 74.25%year -on -year; Chinese materials; Chinese materials; Chinese materials; China Material Technology shipments were 685 million square meters, an increase of 76.19%year -on -year.

In recent years, domestic lithium battery separators have been actively expanding production. Among them, the total planning amount of Xingyuan Material and Enjie Co., Ltd. last year has exceeded 10 billion yuan, which not only increased its pioneering efforts to the domestic market, but also accelerated the entry into the international market. The annual report of 2021 shows that in terms of gross profit margin of overseas business, Enjie shares are 57%and Xingyuan material is 51%.

In terms of domestic markets, since 2021, Enjie has announced the construction of expansion and septum projects in Chongqing, Jiangxi, Jiangsu and other places. After the project is completed, it will expand the production of 1.2 billion square meters, 1 billion square meters, and 2 billion square meters. Xingyuan Material is intended to invest in the construction and production projects of lithium battery diaphragm in Nantong, which will produce a wet diaphragm and coating diaphragm with an annual output of 3 billion square meters. Pu Tailai plans to invest in the construction of a lithium battery septum project over 9 billion yuan in Sichuan and Guangdong Zhaoqing.

In terms of international markets, Enjie has implemented expansion plans in Europe and the United States to accelerate global expansion. In November 2020, Enjie announced that it was invested in the construction of lithium battery separation projects in Hungary. In May 2022, the company reached a strategic agreement with the French ACC company that will provide about 655 million euros of lithium battery separators from 2024 to 2030; the company also announced that it will invest in the United States. Xingyuan material is set up in Sweden. The planned base film production capacity exceeds 700 million square meters and the coating film production capacity exceeds 420 million square meters.

Qi Haizheng, president of Beijing Tyyang Sunshine New Energy Technology Co., Ltd. told reporters: "The lithium battery industry chain and large -scale vehicle manufacturers have become a trend in industrial clustering cooperation."

Improvement of craftsmanship promotes industry differentiation

Benefiting from the high prosperity of the downstream industry, not only the original diaphragm enterprises are constantly planning production capacity expansion, but the number of new enterprises is also growing. The competition in the septal industry is increasing. Excellent diaphragm manufacturers are expected to occupy more market share.

Technical levels will greatly affect the competitiveness and profit level of diaphragm enterprises. Enjie's comprehensive product rate in 2015 was 53%. After the improvement of the process, the comprehensive good product rate in 2017 reached 78%.

Hua'an Securities said that the high barriers of the septum industry are mainly reflected in the four dimensions of production equipment, technology and technology, funds, and customers. First of all, the production capacity of the diaphragm production line is scarce; second, the production process of septum production process is difficult to upgrade, the product has a low rate of good products, and it is difficult to improve the yield of good products through the process, which requires a long period of accumulation. The amount of funds is large; in the end, the certification threshold and long cycle of the downstream customers in the septum industry are high.

The degree of improvement of diaphragm production technology will promote the significant differentiation of the industry pattern. Meng Xiangxu said: "As a leading company in the diaphragm industry, Enjie and Xingyuan materials, the diaphragm products have maintained a high rate of good products. In recent years, it has maintained more than 80%. Other manufacturers in the industry have been difficult to surpass in the short term, and have formed obvious technical barriers. The requirements of diaphragm products have high requirements for thickness, mechanical performance, breathability, and physical and chemical performance. The technical points involved in the septum production line of different manufacturers are also different, and the technical improvement has higher requirements for technical personnel. "
