What is the function of cr2032 3v lithium battery separator materials?

　　1. Provide safety precautions for the battery: The diaphragm material must first have good dielectric strength to avoid short circuit failure due to positive and negative contact or short circuit failure caused by burrs, particles, or twins. Therefore, the diaphragm The film must have a certain tensile and puncture strength, not be easily torn, and basically maintain a stable size under sudden high temperatures, and not be easy to shrink, causing large-scale short circuit failure and thermal failure of the battery. .

　　2. Lithium batteries provide micropore channels to realize battery charging and multiple performance: Therefore, the diaphragm must be a plastic film with high porosity and uniform distribution of micropores. The characteristics of the raw material itself and the porosity characteristics after demulsification restrict the transfer of lithium-ion batteries in rechargeable batteries, which is reflected in the technical parameter as positive ion conductivity.

　　The diaphragm is an important component of lithium batteries. It is located between the positive and negative points inside the battery, ensuring the passage of the lithium-ion battery and blocking the transmission of electronic devices. The properties of the diaphragm determine the surface structure, internal resistance, etc. of the battery, which directly affects the battery's capacity, circulation, and safety. A diaphragm with excellent properties plays an important role in improving the overall performance of the battery.

　　With the rapid development of lithium batteries, the sales market and development prospects of diaphragm membranes are very promising. Due to its unique structure and characteristics, polyolefin microporous plate membranes occupy the most dominant position in liquid lithium batteries; with the increasing demand for lithium The improvement in battery performance requirements has diversified the production methods of diaphragms, the production process has gradually improved, modified material technology has been widely studied, and new cr2032 3v lithium battery separators have also gained certain development trends.
