Global Lithium-Ion Battery Dry Separator Market Strategic Research Report

Scope of the Report

Lithium-Ion Battery Dry Separator can be subdivided into uniaxial stretching processes and biaxial stretching processes. The dry uniaxial stretching process is to prepare a low-crystallinity highly oriented polypropylene or polyethylene film by producing hard elastic fibers, and obtain a high-crystallinity film during the high-temperature annealing process. This film is first stretched at low temperatures to form micro-defects, and then at high temperatures the defects are pulled apart to form micropores. The performance of the separator in the dry biaxial stretching process is poor, and it can only be used for low-end batteries. Therefore, the dry uniaxial stretching process and the wet process are currently the mainstream preparation processes.

Separator is one of the four key materials of lithium-ion batteries (separator, electrolyte, positive electrode material, negative electrode material). The cost accounts for about 25% of the total cost of lithium battery, and the gross profit margin is 40%-60%. It is one of the four main materials of lithium battery. Products with the highest gross profit margin. As a key inner component of the lithium-ion battery, the separator separates the positive and negative electrode materials, prevents the two poles from contacting and causing a short circuit, allows ions to pass but does not allow electrons to pass, thereby completing the process of charging and discharging lithium ions between the positive and negative electrodes. fast transfer. The performance of the separator directly affects the internal resistance, discharge capacity, cycle life, and battery safety performance of the battery.
