The use of lithium battery diaphragm

Diaphragm is one of the important inner components in the structure of lithium battery. The characteristics of the diaphragm determine the page structure and internal resistance of the rechargeable battery. It immediately endangers the capacity, circulation system and safety factor of the rechargeable battery. Excellent diaphragm characteristics are the key element to improve the comprehensive performance of rechargeable batteries. The technical difficulty of the diaphragm depends on the production process of the hole and the preparation of the plate. The hole making engineering design contains the pulse damper hole making technology, processing line equipment and product reliability. The key scientific research is the preparation of polypropylene, high-pressure polyethylene raw materials and preservatives and the production process of modified materials. Insufficient porosity, uneven thickness and poor compressive strength are difficult problems in the design of pore-making engineering. The use of the lithium battery diaphragm: the key to the use of the diaphragm in the lithium battery is reflected in two levels: first, to ensure the safety factor of the rechargeable battery. Diaphragm materials must first have excellent dielectric strength. Beware of short-circuit failures caused by positive and negative touches, or short-circuit failures caused by burrs, particles, or crystals. Therefore, the diaphragm must have a certain degree of tensile strength. Compressive strength, not easy to tear, and long-term maintenance specifications under the sudden high temperature standard, it is not prone to shrinkage, resulting in large-scale short-circuit failure and uncontrollable heat. Second, the other is to supply lithium batteries with a microplate safe channel with charging purpose and multiple characteristics. Therefore, the diaphragm must be a plastic film with high porosity and well-proportioned microplates. The transfer of lithium batteries in rechargeable batteries is constrained by the characteristics of the raw materials themselves and the porosity characteristics after demulsification. The current technical parameters are the positive ion oxidation-reduction potential. Because diaphragm raw materials are becoming more and more colorful, the processing and production of machinery and equipment and wearing parts are becoming more and more perfect. The high regulations on the cutting machine blades will greatly promote the cutting of high-tech, high-quality and stable carbide tools. The requirements of the knife also present an excellent opportunity for the development trend of the CNC blade category.
