What kinds of separator materials for lithium iron phosphate batteries?

What is the separator material of lithium iron phosphate batteries? The separators of lithium iron phosphate batteries can be divided into different types according to the structure and composition. There are three common and important ones on the market now, namely porous polymer membranes, non-woven membranes and Inorganic composite membrane. 1. Porous polymer membrane refers to a lithium iron phosphate battery separator with uniform pore distribution prepared by mechanical methods, thermally induced phase separation methods, immersion precipitation methods and other methods. 2. The non-woven fabric separator is composed of oriented or random fibers, and is usually compounded with organic matter or ceramic gel to obtain a lithium battery separator with better chemical and physical properties. 3. Inorganic composite membranes are mostly lithium iron phosphate battery separators that are composited with inorganic nanoparticles and high polymers. Development status and prospects of lithium iron phosphate battery separator materials. my country’s lithium iron phosphate battery separator industry is in a stage of rapid development. Wet-processed separators have gradually become the mainstream technical route, but at the same time, the overall technical level of domestic separators and the level of international first-line companies are still relatively large. gap. At present, the lithium battery separator market in my country in 2019 can be said to be very bad. One is that the output is severely surplus due to the early state investment policy; the other is the national new energy industry policy, the state subsidies for power vehicles have fallen, and the subsidy requirements have increased. Lithium battery manufacturers have major problems in the capital chain, and lithium battery manufacturers have also put forward new requirements for diaphragm suppliers in terms of price, quality, and billing period.
