What kind of lithium battery testing equipment is good for lithium battery negative pole piece testing?

What lithium-ion battery testing equipment is used for lithium-ion battery cathode film testing

At present, lithium-ion batteries are widely used in our lives, such as mobile phones, household appliances, etc. At the same time, their natural dangers are gradually emerging, such as Dell, Apple, and other international brands also have a similarly embarrassing situation.

The continuous mobile phone spontaneous combustion incident not only sounded the alarm for the industry but also prompted experts to conduct more in-depth research on mobile phone spontaneous combustion. After many internal tests and analyses, it is important that the lithium-ion battery is compressed due to the internal negative plate, and some lithium-ion batteries are short-circuited due to the thin insulating tape, resulting in the spontaneous combustion of the mobile phone.

The spontaneous combustion of all mobile phones is caused by the short circuit of the lithium-ion battery. The short circuit phenomenon is formed by the internal defects of the lithium-ion battery. The structure of the lithium-ion battery itself is a manufacturing process. Any abnormal situation may pose a serious threat to the safety of the lithium-ion battery. . There may be a thick layer of plastic aluminum alloy outside the lithium-ion battery so we can't understand the internal short circuit of the lithium-ion battery with the naked eye. At this time, we can use the surface density X/β Dacheng precision instrument, without disassembling Under the premise of lithium-ion batteries, the shell can be easily penetrated, and the defects inside the lithium-ion battery can be clearly and accurately identified from the computer screen.
