As a Ni-MH Battery Pack Supplier, share with you. The diaphragm is one of the
important inner components in the structure of lithium batteries. The
characteristics of the diaphragm determine the page structure and internal resistance of the rechargeable battery. It immediately endangers the volume,
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 hole making process and the preparation of the plate. The hole making engineering design includes the pulse damper hole making process, production line equipment and product reliability. The key scientific research is the preparation of polypropylene, high-pressure polyethylene raw materials and preservatives and the processing technology of modified materials. Insufficient porosity, uneven thickness and poor compressive strength are difficult problems in the design of pore-making engineering.
The role of lithium battery diaphragm:
The key role of the diaphragm in lithium-ion batteries is reflected in two levels:
First, ensure the safety factor of rechargeable batteries. Diaphragm materials must first have excellent dielectric strength to avoid 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 tensile strength. Compressive strength, not easy to tear, and long-term maintenance specifications based on sudden high temperature standards, it is not easy to produce shrinkage, resulting in large-scale short-circuit failure and uncontrollable heat.
Second, the other is to provide a safe channel for lithium-ion batteries with a microplate with charging function 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 redox potential.
Because diaphragm raw materials are becoming more and more colorful, the production and processing of machinery and equipment and wearing parts are becoming more and more perfect. The high regulations on 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 in the field of CNC blades.
