Clarify the growth trend of lithium-ion battery barriers and the growth of lithium-ion battery barriers

As an important component of lithium-ion batteries, lithium battery barriers account for 5-10% of the total cost of lithium battery materials. Following the rapid growth of my country's new energy vehicles, industry insiders have suggested that this will bring new opportunities for the growth of lithium-ion battery-related wealth, especially the wealth of battery barriers. Lithium battery barriers to speed up the wealth of institutions. According to the knowledge, barriers is a high value-added material with the highest technical barrier in lithium battery materials. It is also one of the key components in the layout of lithium-ion batteries. Its cost accounts for about 20-30 of the total cost of lithium-ion batteries. %, the gross profit rate can reach more than 60%, and the excellent performance barrier has an important purpose to improve the comprehensive performance of the battery. However, although the profits of the barriers are considerable, due to the lack of focus skills and other reasons, the barriers currently used in our country are mostly. Over the years, the country is also accelerating the growth of the wealth of the battery barrier. With the rise of new energy vehicles, the demand for lithium-ion batteries is vast. According to statistics from the National Bureau of Statistics, the cumulative production of new energy vehicles from January to June this year has reached 285,000, a year-on-year increase of 88.7%. From the perspective of barrier demand, since 1GWH battery's corresponding loss of barrier demand is about 20 million square meters, the emergence of the new energy vehicle and power lithium battery market will further open up the future market space for the lithium battery barrier industry, which has also attracted many Listed companies are speeding up the scale of lithium battery barriers. Suzhou Jieli, a subsidiary of Shengli Close Group, has two original production lines for wet-process lithium-ion batteries with an annual output of 70-80 million square meters. They have been supplied to first-line customers such as CATL, LG, SDI, etc., and the current market The downstream demand is strong, and the product supply cannot be demanded. Lithium-ion battery barrier market growth Judging from the trend in 2019, leading companies will increase production, promote internal comprehensive management, and increase investment in new achievements to further reduce costs and widen the gap with third- and fourth-tier companies. Lithium-ion battery barriers belong to the asset-heavy industry. Under the environment of increased differentiation between companies, the planning pressure faced by the late-echelon companies has increased sharply. GGII estimates that in 2019, there will be departmental barriers and the company may close down and may stop production. The future growth trend of lithium-ion battery barriers is to improve the barrier heat resistance. The advancement of skills, the growth of society, and security issues will definitely receive more and more attention from the society, so the heat-resistant function of handling barriers is very important. For example, Mitsubishi Paper Co., Ltd. coated ceramic ions on a non-woven fabric barrier composed of polyester fibers to enhance the high temperature resistance of the battery barrier, which can withstand high temperatures of 470°C. The second is to develop ultra-thin barriers. With the growth of the market, lighter, thinner and smaller electronic products will continue to enter the daily life. Such products require thinner lithium-ion battery barriers to build batteries. At the same time, the pursuit of capacity for lithium-ion batteries should also be thinner and thinner. It tends to grow, but the production and preparation of ultra-thin barriers requires high equipment and technology. The third is to develop new types of barrier products such as polymer electrolyte barriers and fiber barriers. Power lithium batteries face higher challenges in terms of high-power fast charge and discharge and various functions of safety. This also makes the main materials used in lithium batteries grow from polyolefin materials to multiple materials and composite materials. The layout has also grown from a simple layout to a huge layout. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
