What are the technical advantages of CR2450 battery separator testing? Introduction to CR2450 battery separator materials

　　What are the technical advantages of CR2450 battery separator testing? Introduction to CR2450 battery separator materials. As the core material of lithium-ion batteries, the separator is used to separate the positive and negative electrodes of the battery to prevent safety issues caused by contact between the positive and negative electrodes. At the same time, its microporous structure allows the electrolyte ions to pass through. So, what is the CR2450 battery separator material? What are the advantages of CR2450 battery separator testing? Let me introduce it in detail below.

　　What are the technical advantages of CR2450 battery separator testing?

　　The use of machine vision technology for CR2450 battery surface inspection uses unified standards, so it is not affected by factors such as manual fatigue, emotion, misjudgment, etc. It can greatly improve production efficiency and yield rate, and can also reduce labor costs and returns and rework. cost, achieving safety, speed, convenience and quality and quantity. At the same time, the online machine vision automatic high-speed intelligent detection system for CR2450 battery separator surface defects provides real-time comprehensive and accurate ultra-clear image reports of defects, and timely processing improves the quality of CR2450 battery separator material products.

　　The online detection system for surface defects of CR2450 battery separators is based on machine vision image processing technology. It integrates the current leading image acquisition, photoelectric recognition, and machine vision image software and hardware equipment for image analysis and processing of CR2450 battery separators, realizing online high-speed identification. If there are surface defects or blemishes in the CR2450 battery separator, an alarm will be prompted when defects are found, and surface defects will be visually displayed for classification. Abandon the "original" online quality inspection that relies on cumbersome and low-quality artificial naked eye methods.

　　Excellent separators play a very important role in improving the overall performance of lithium batteries. Their performance affects the structure, resistance, capacity, cycle and safety performance of the battery, especially the puncture resistance, self-shutoff, high temperature resistance and other properties of the separator. It is the main guarantee for the internal safety of lithium batteries.

　　Advantages of CR2450 battery separators

　　1. Heat resistance: Enhance the high temperature resistance of the battery separator

　　2. Ultra-thin separator: The pursuit of capacity of lithium batteries requires the development of thin and light films.

　　3. The liquid absorption performance of the separator: can increase the capacity of the battery

　　Introduction to CR2450 battery separator materials

　　In the structure of lithium batteries, the separator is one of the key inner components. The performance of the separator determines the interface structure, internal resistance, etc. of the battery, which directly affects the battery's capacity, cycle, safety performance and other characteristics. Excellent separators play an important role in improving the overall performance of the battery.

　　The main function of the separator is to separate the positive and negative electrodes of the battery to prevent the two electrodes from contacting and causing a short circuit. In addition, it also has the function of allowing electrolyte ions to pass through. The separator material is non-conductive, and its physical and chemical properties have a great impact on the performance of the battery.

　　Commercial lithium-ion battery separator products are mostly microporous membranes made of polyolefin materials. Polyolefin materials have the advantages of high strength, good acid and alkali corrosion resistance, waterproof, chemical resistance, good biocompatibility, and non-toxicity. Industrial preparation is mature.

　　Factors affecting membranes include thickness, air permeability, wettability, pore structure and porosity, thermal stability and consistency, etc. Excellent separators play an important role in improving the overall performance of power lithium batteries, so higher requirements are put forward for the use of CR2450 battery separators:

　　(1) It must have good insulation to prevent the positive and negative electrodes from contacting short circuits or being punctured by burrs, particles, and dendrites;

　　(2) It has sufficient puncture strength, tensile strength, etc., and basically maintains dimensional stability under sudden high temperature conditions, and will not melt and shrink, causing large-area short circuits and thermal runaway of the battery;
