PE Battery Separator
Our company has many years of experience in the field of lithium battery separators. At present, there are two production processes, wet method and dry method.
SPECIFICATIONS
The raw materials used in the dry method are of good fluidity and low molecular weight (ie, simpler raw materials), so the high temperature can only reach 135 degrees (thermal shutdown temperature), and it will shrink (<5%) when heated, and Safety is not suitable for high-power, high-capacity batteries; dry method can do three-layer film, the advantage of three-layer film is that the thermal shutdown temperature is 135 degrees, but the thermal stability temperature is 160 degrees, which can prevent thermal inertia, there is a space of 25 degrees, which is safer.
The wet method uses non-flowing, high molecular weight raw materials, and the thermal shutdown temperature can reach 180 degrees (the ceramic inorganic separators can reach 200 degrees), which can ensure the safety of high-power batteries; the wet method can only be used as a single-layer film
In the production of general lithium batteries, the dry method has advantages, such as low cost, less pollution, and more uniform pores; in terms of high-power batteries, the wet method has advantages, mainly in terms of safety and thermal shrinkage.
