Lithium battery separator production line -Lithium - Ion Battery Equipment
1. Dry uniaxial stretching production line;
2. Dry biaxial stretching production line;
3. Wet biaxial stretching production line.
●Dry uniaxial stretching production line
The dry uniaxial stretching production line uses PP or PE as the important raw material, mixes various grades of auxiliary materials and mixes them fully, extrudes them by the casting method, and then passes through the multi-layer compounding machine and then uniaxially stretches them. The stretched multi-layer separator is layered and cut by the machine, and the slitting machine is used to produce a uniaxially stretched lithium battery separator. Equipped with high-precision testing instruments, it adopts the production process jointly developed with famous scientific research institutions in my country, and mainly produces lithium-ion battery separators with different thicknesses ranging from 16μm to 40μm.
The large-scale production of lithium-ion power lithium battery separators by dry uniaxial stretching process can simultaneously stretch more than multiple layers of base films (total thickness above 250μm), which greatly improves production efficiency and greatly reduces production costs. This production line can produce films of different thicknesses and layers, runs smoothly, and all functions and performance indicators meet the technological requirements, which has won wide acclaim and unanimous praise from Cangzhou Pearl.(Lithium - Ion Battery Equipment)
The production line of dry uniaxial stretching process lithium ion battery separator has passed the acceptance inspection. The important production thickness is 12-60 microns, and the lithium ion battery separators of different specifications are widely used in power lithium ion batteries, energy storage lithium ion batteries and digital lithium ion batteries. Battery.
●Dry biaxial stretching production line
Using PP as an important raw material, mixing various grades of auxiliary materials, fully stirring, extruding and forming by the casting method, biaxially stretching and winding, and then slitting to produce a biaxially oriented lithium battery diaphragm. Equipped with high-precision testing instruments, it adopts the production process jointly developed with famous scientific research institutions in my country, and mainly produces lithium-ion battery separators with different thicknesses ranging from 12μm to 40μm.
●Wet biaxial stretching production line
Taking PE as an important raw material, mixing various grades of auxiliary materials, fully stirring, extruding through the casting method, biaxially stretching, forming holes through the extraction process, and then rolling and slitting after transverse stretching to produce a wet method. Biaxially stretched lithium battery separator. Equipped with high-precision testing instruments, it adopts the production process jointly developed with famous scientific research institutions in my country, and mainly produces lithium-ion battery separators with different thicknesses ranging from 8μm to 25μm.
Wet process lithium ion battery separator biaxial stretching production line Lithium ion battery separator materials can be divided into: woven film, non-woven film (non-woven fabric), microporous film, composite film, separator paper, rolled film and so on. Polyolefin materials have excellent mechanical properties, chemical stability and relatively cheap characteristics, so polyolefin microporous membranes such as polyethylene and polypropylene have been used as lithium-ion battery separators in the early stage of lithium-ion battery research and development.
