A new round of expansion of lithium battery diaphragm 'starts'

Lithium-ion batteries are fully blooming in many market segments such as new energy vehicles, energy storage, two-wheelers, and power tools, driving a strong rise in demand for lithium-ion battery separators. At present, domestic diaphragm production and sales have repeatedly hit new highs. The diaphragm leader has continued to produce full production, and the output supply is tight. The production utilization rate of the second and third echelon diaphragm companies has also continued to increase. In order to further meet market demand, Head Diaphragm Company began to deploy expansion projects or accelerate production release. On May 19, Cangzhou Mingzhu announced that it plans to invest in the construction of '200 million square meters of wet-process lithium-ion battery separator project' in Cangzhou, with an investment of 620 million yuan. It is important to build two wet-process lithium-ion battery separator production lines for the production of wet-process lithium-ion battery separator products. Just one day ago, Sinoma Technology announced that Nanjing Lithium Membrane, its wholly-owned holding company, plans to build a '1.04 billion square meters lithium-ion battery separator production line' in Nanjing, with a project investment of 3.753 billion yuan. It is important to construct 4 single-line production lines of 80 million square meters per year, 8 single-line production lines of 100 million square meters per year for lithium-ion battery base film production lines, and 6 single-line production lines of 50 million square meters per year of oil-based coating diaphragm production lines. In answering investors’ questions, Xingyuan Material also stated that this year the company will continue to actively explore the overseas lithium-ion battery separator market to further increase the company’s international market share; actively expand production and enhance the company’s business capacity. It is worth noting that the current price of the diaphragm remains stable, and it is difficult for the diaphragm to increase its price when there is no substantial increase in demand and no continuous supply shortage. The price of domestic 7m wet base film is maintained at 1.7-2.3 yuan/square meter, the price of 9m wet base film is about 1.0-1.3 yuan/square meter, and the price of 16m dry base film is maintained at 0.9-1 yuan/square meter. GGII predicts that the diaphragm market competition in 2021 will present the following characteristics: First, the production of head diaphragm companies will accelerate, the effect of production scale will be further manifested, and the cost will decrease slightly, which will increase the market concentration of the head companies; second, the head diaphragm companies Binding with battery customers has deepened, overseas exports and plant construction have accelerated, second-tier diaphragm companies continue to seek cooperation with leading companies; third, diaphragm companies will accelerate the layout of core patents (including thinner and thinner, composite coating, etc.), 5 product markets The promotion of chemical applications has accelerated; fourth, market differentiation and competition have intensified, and industry integration and elimination continue.
