Introduction to the use of lithium ion battery diaphragm

The key to the use of diaphragm in lithium-ion batteries is reflected in two levels: First, to ensure the safety factor of rechargeable batteries. Diaphragm materials must first have excellent dielectric strength to prevent 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 maintain specifications for a long time under the sudden high temperature standard, and it is not prone to shrinkage, resulting in large-scale short-circuit failure and uncontrollable heat. Second, the other is to supply lithium-ion 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-ion batteries in rechargeable batteries is constrained by the characteristics of the raw materials themselves and the porosity characteristics after demulsification, which is mainly manifested in the technical parameters, that is, 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 high-tech, high-quality and stable carbide cutting tool. The requirements of the knife also present an excellent opportunity for the development trend in the field of CNC blades.
