The rapid expansion of the lithium-ion battery industry has driven the rapid growth of the entire diaphragm industry. According to the starting point study (SPIR) statistics, the global lithium-ion battery separator production increased from 500 million square meters in 2010 to 1.42 billion square meters in 2015, an increase of nearly three times. In 2016, the global lithium-ion battery separator production reached 1.719 billion square meters. With the introduction of subsidies for new energy vehicles, high-energy-density ternary batteries have become an important direction for the strategic layout of lithium-ion enterprises at home and abroad. Lithium-ion enterprises have set off a wave of ternary battery expansion, benefiting from the demand for ternary batteries, and the wet-membrane The volume of goods and demand has soared, and the proportion of coated diaphragms has increased rapidly. The starting point study (SPIR) data shows that in 2017, the ternary battery has become an important position for the strategic layout of lithium-ion enterprises. By 2020, the demand for ternary batteries can reach 55.4GWh (including passenger cars) or 50.5GWh (excluding passenger cars), compared with 2015. Increased by 11.6 times or 10.5 times. The market share of the wet diaphragm will increase significantly, and it is expected that by 2020, the wet diaphragm in the domestic diaphragm will exceed 70%. The industry has set off a wave of diaphragm companies Driven by the demand for ternary batteries, wet diaphragm shipments and demand surged, and the market share of wet diaphragms will increase significantly. Domestic lithium battery separator companies have greatly expanded their production capacity, and the Nuggets wet diaphragm blue ocean. The data shows that as of now, the domestic lithium battery diaphragm planning capacity has reached 840 million square meters. In addition, about 40 companies are under construction or plan to invest in lithium battery separator projects. Star source material As the leading diaphragm manufacturer in China, the production capacity in 2017 is expected to be close to 300 million square meters. The product positioning is high-end, and the power battery category accounts for more than 95%. The company's 380 million yuan investment in the third-generation high-performance lithium battery separator project, the second phase of the new dry process capacity of 0.5 billion square meters is expected to be put into production in the second quarter of 2017, Hefei Xingyuan wet process capacity of 80 million square meters or will be advanced to 2017 In production. Zhangzhou Pearl With the capital, technical advantages and resources of listed companies, Zhangzhou Mingzhu expands the production capacity of dry and wet diaphragms through a multi-pronged approach of cooperation with battery companies and fixed fundraising, stabilizing the status of the industry and ensuring adequate supply capacity. On January 25, 2016, Zhangzhou Pearl and China National Aviation Corporation established a joint venture to establish a 105 million square meter wet lithium ion battery separator project. Three wet diaphragm production lines will be built and are expected to be completed in February 2018. By then, the company's total wet diaphragm capacity will reach 190 million square meters. Jinli In February of this year, Jinli invested RMB 17.4581 million to build the third and fourth wet diaphragm production lines. In addition, the company's production capacity of 25 million square meters of No. 2 wet diaphragm production line was officially put into operation in December 2016. The engineering and equipment have been completed. The acceptance is qualified, the performance of each product is up to standard and the sales order has been signed. Newm Technology Starting in 2017, Nuomi Technology will accelerate the construction of wet diaphragm and coating production lines, launch four wet diaphragm production lines and four coated diaphragm production lines, and the annual production capacity of Nuomi's diaphragm will reach 550 million square meters in the next 5 years. The annual production capacity of the diaphragm is 350 million square meters. On January 25 this year, Chongqing Nuomi Technology raised funds of 140 million yuan. It will be used to increase the capital of Kunming Yuntianhua Newmea Technology Co., Ltd., a wholly-owned subsidiary of the company, and provide pre-project start-up funds for the company to build a new high-performance lithium-ion battery microporous wet diaphragm project with an annual production capacity of 2*30 million square meters. Medium lithium new material At the end of 2016, China Lithium New Materials completed the construction of eight high-end lithium-ion battery separator wet production lines for new energy vehicles, with an annual production capacity of 324 million square meters. It is planned to complete the construction of 20 wet diaphragm production lines in the first half of 2018. After the completion of the construction, the production capacity will reach 1 billion square meters. It will become the most advanced and largest lithium ion battery diaphragm research and development and production base in China. Enjie new material Enjie New Materials signed the investment agreement for the lithium battery separator South China Base Project. The South China base of the largest domestic lithium-ion diaphragm manufacturer, Enjie New Materials, settled in Gaolan Port, with a total investment of about 2 billion yuan to build a diaphragm production line and a coating production line. It is reported that the project is located in Gaolan Port Equipment Manufacturing Zone, covering an area of ​​180,000 square meters. The first phase will invest 1.28 billion yuan to build 7 diaphragm production lines. It is expected to achieve sales of 2.9 billion yuan. The first production line is expected to be The trial production will begin in June next year. In addition, in the second phase of the project, while constructing 3 to 6 diaphragm production lines, 29 coating production lines will be planned and constructed. Low-end diaphragm overcapacity looming gross profit decline With the lithium battery separator business strategic layout continue to overweight, lithium battery separator market competition becoming increasingly fierce. On the one hand, with the influx of a large number of manufacturers in the low-end diaphragm market, the price of low-end diaphragms continues to decline. According to the data released by Xingyuan Materials, the average selling price of the company's products decreased from 6.11 yuan/m2 in 2013 to 4.49 yuan/m2 in the first half of 2016, and the price cuts in 2014, 2015 and the first half of 2016. They were 6.32%, 12.07%, and 10.70%, respectively. Although the current market competition is further intensified, and the entire lithium battery separator industry may face overcapacity. If all the diaphragm enterprise planning projects are put into production, the production capacity will reach 2.3 billion square meters, even exceeding the global market demand. For the future expansion plans of several large power battery customers downstream, it is expected that the new demand for power battery separators will exceed 370 million square meters in 2017, and the total demand will reach 850 million square meters. On the other hand, the decline in the price of the power battery is transmitted to the upstream diaphragm material, and the price of the wet diaphragm in early February 2017 is about 9% lower than that in December 2016. The subsidies for new energy vehicles have fallen sharply, which has pushed down the price of power battery manufacturers. As the new energy vehicle manufacturers are still in the adjustment period, the current power battery companies have started to work flat, and the order volume has dropped by more than 20%. The large expansion of power batteries led to overcapacity. In 2016, the domestic power battery capacity was 2.8 times that of 2015, while output increased by only 82%. Data show that in early February 2017, the price of power batteries fell by more than 15% from December 2016. The overall capacity of power battery is excessive, the industry will face differentiation, and the diaphragm production capacity will increase more. The high gross profit of the diaphragm industry will also decline. High-end wet diaphragm gap is huge Domestic lithium battery separator companies are insanely put into production, but the high-end wet diaphragm has a huge gap. Due to the high barriers to production technology, the long construction period of the production line, and the uncertainty of the production time and actual production capacity, the current high-end wet diaphragm is still mostly imported, and the high-end diaphragm gap is also growing. It is expected that the domestic high-end wet diaphragm will continue to be in short supply by 2018, and it has been in a net import state. More than 60% of the diaphragm's mid-to-high-end market is still occupied by foreign diaphragm manufacturers such as Japan and South Korea. The replacement space of the middle and high-end market of the diaphragm is huge. . With the expansion of ternary batteries and the demand for high-energy-density batteries, the market demand for diaphragms continues to increase, and new requirements are being placed on new technologies such as coating diaphragms. Lithium battery separator companies should pay more attention to the improvement of diaphragm technology while expanding production.
