What is the price trend of lithium-ion battery separators this year?
The unit price of lithium-ion battery separators constitutes the processing cost of lithium-ion battery separators. The largest part of the cost lies in the depreciation and labor costs of the equipment, accounting for nearly half. The important raw materials polyethylene, methylene chloride and white oil account for about 30 %, electricity and gas account for about 20%. In the same period, the unit price of semi-finished base film was 3.76 yuan/square meter, 3.85 yuan/square meter and 3.04 yuan/square meter, a decrease of 19.15%; the unit prices of finished products were 4.13 yuan/square meter, 4.3 yuan/square meter and 4.12 yuan/square meter . The unit price of base film for 2015-2016 and January-August 2017 is 4.29 yuan/square meter, 4.02 yuan/square meter and 3.82 yuan/square meter; the unit price of coated film for 2016 and January-August 2017 is 6.82 Yuan/square meter and 6.08 yuan/square meter, the decline both exceeded 10%. In terms of price, with the continuous release of production and continuous improvement of technology, the price of lithium-ion battery separators has been declining in recent years. As of the first quarter of 2018, the average prices of wet-process diaphragms, dry-process single-pull diaphragms, and dry-process double-pull diaphragms were 2.9 yuan/square meter, 1.9 yuan/square meter and 1.5 yuan/square meter, respectively. It can be seen from the production and production trends of diaphragms that wet diaphragms are an important direction for the diaphragm industry in the future, and the market share will continue to increase. Compared with the domestic market, the price trend of lithium-ion battery separators in 2019 is relatively small in foreign markets. At the same time, the company's target market is the mid-to-high-end market, and the price reduction is relatively small; the company uses technological advances to reduce processing costs, thereby offsetting the decline in prices Influence. The company is positioned as a global company, and the proportion of export sales will gradually increase. Lithium-ion battery separators belong to the material industry and are capital-intensive industries. Only high gross profit can support the development of the industry. We believe that around 40% of gross profit margin is an equilibrium level. Through technological improvement, while improving processing efficiency and yield level, reducing costs, and increasing the proportion of overseas sales, etc., the gross profit margin is kept relatively stable. The domestic lithium battery diaphragm industry has a low production utilization rate, and the use is mainly concentrated in the low-end category. High-end applications such as power lithium battery mainly rely on imports. The price of dry-process diaphragms has dropped by about 70% compared with 3 years ago, and the gross profit rate has dropped to about 25%. Wet diaphragm technology is not yet mature. At present, the price of lithium-ion battery separators manufactured by dry process is already very low, at about 5 yuan/square meter, and the price will continue to fall in the future. The profit margins are already very low; the price of wet process separators is 10-12 yuan/ There are almost no domestic companies that are capable of large-scale processing, and the gross profit margin of this business can reach 50%.
