The separator is used to separate the positive and negative poles during electrolysis reactions in order to avoid a direct reaction in the electrolytic cell. A thin film that loses energy. In the structure of lithium batteries, the separator is one of the key internal components. The performance of the separator determines the structure of the interface, the. internal resistance, etc. of the battery, which directly affects the capacity, le cycle and safety performance of the battery. Excellent separators play an important role in improving the overall performance of the battery.
The production methods of lithium battery separators are mainly divided into two types:
1. Melt stretching method
The preparation principle is that the molten polymer crystallizes under a high stress field to form a lamellar structure perpendicular to the direction of extrusion and arranged in parallel, then undergoes heat treatment to obtain a so-called hard elastic material. After stretching the hard elastic polymer film, the lamellae separate and a large number of microfibers appear, thereby forming a large number of microporous structures. The microporous film is then heat-set. Products such as the American Celgard diaphragm.
2. Thermally induced phase separation methodnt
The thermally induced phase separation method is a method for preparing microporous membranes that has been developed in recent years. It uses polymers and certain small molecular compounds with high boiling points to form a homogeneous solution at a higher temperature (usually above the melting temperature of the polymer), thereby reducing the temperature will cause solid-liquid phase separation or liquid-liquid, so that the polymer-rich phase contains the additive phase and the additive-rich phase contains the polymer phase. After stretching, low molecular weight substances can be removed to manufacture. interpenetrating microporous membrane materials.
