What is the production and testing process for lithium-ion battery polymers

In order to ensure the safety of lithium-ion batteries, various safety testing standards for lithium-ion batteries have been developed at home and abroad. Among them, the general test standards will usually be divided into safety test items: electrical test: over charge, over discharge, external short circuit, forced discharge, etc.; Mechanical test: extrusion, needling, vibration, drop, etc. Heat dissipation test: high and low temperature cycle, combustion, microwave heating, etc. Environmental simulation: high altitude and low pressure simulation, salt spray test, etc.
 

With the wide use of lithium polymer batteries in the field of mobile communication and electronic equipment, their safety incidents have been repeatedly exposed. Testing lithium-ion batteries is a routine for many electronics manufacturers. So what are some of the reasons for testing lithium-ion batteries?

First of all, adhere to the concept of green environmental protection. Although lithium polymer batteries have brought a lot of benefits to people's lives, it should not be ignored that various elements in batteries have great damage to soil, water quality and ecological environment. By testing the lithium-ion battery, the remaining electrical energy can be recycled many times, and after a series of perfect work, the electromagnetic can be reborn. Lithium-ion battery testing is the work advocated by the modern green production concept, and it is the need of the whole industrial chain.

Second, to provide consumers with better after-sales protection. It is important to remember that the lithium-ion battery testing service is aimed at electronics manufacturers, but the actual target of the service is mainly electronics consumers. Manufacturers often use lithium-ion battery testing services to increase consumer acceptance of their products. Regular testing of lithium-ion batteries in electronic devices can also eliminate safety hazards in the first place and provide better battery after-sales, maintenance and testing services to consumers in the market.

Finally, ensure the safety and quality inspection process of lithium battery production. The presence of elements such as lithium alloys in the production of lithium-ion batteries not only makes the production process complicated, but also makes it expensive. But because the battery is wrapped in a thick layer of plastic or aluminum alloy, it is impossible to see what is going on inside. At this point, we can use X-ray inspection equipment to easily penetrate the shell, to view the internal structure of the lithium battery, to ensure the safety of the lithium battery in the production and quality inspection process.

In general, all testing techniques are for quality assurance! Science and technology come from life and serve life. Rational use of new technology and equipment can effectively improve production efficiency and ensure production and use safety. In order to ensure the safety of the battery, please check the unqualified battery and avoid battery safety accidents.

In addition, all the tests mentioned above are for the inspection of finished lithium polymer batteries, but if the inspection process can also be added in the production process of lithium polymer batteries, the qualified rate of finished batteries can be effectively improved. The structure of the battery includes a shell, an upper cover, a plate, a partition plate, a bus, a pole, a bridge protection plate, and a terminal. The production process is complex and also impossible to inspect visually. Therefore, X-ray real-time imaging technology is indeed a good choice. X-rays are emitted and penetrated through the X-ray generator, and then the imaging system receives the X-rays and takes pictures. Then the images are processed by the relevant software for automatic measurement and judgment, so as to identify the internal defects of the lithium battery.
