CR2025 battery

　　Does the preparation technology of CR2025 batteryfrom different manufacturers also affect the safety performance of batteries?

　　How to safely use lithium battery packs to prevent battery explosion? Safety is an important factor hindering the development of lithium battery packs. In recent years, there have been frequent reports of accidents involving lithium battery combustion and explosions, such as the explosion of Samsung Galaxy Note 7, spontaneous combustion of Tesla electric vehicles, fires in lithium battery factories, etc. So what measures should we take and how to use lithium battery packs to prevent battery explosion?

　　Why do lithium CR2025 batteryexplode?

　　Explosion type analysis: The types of battery core explosions can be summarized as external short circuit, internal short circuit, and overcharge. The safety issues of lithium-ion CR2025 batteryare not only related to the properties of the battery materials themselves, but also to the battery preparation technology and use.

　　1. Large internal polarization;

　　2. The pole piece absorbs water and reacts with the electrolyte;

　　3. Quality and performance issues of the electrolyte itself;

　　4. When injecting liquid, the amount of liquid injected does not meet the process requirements;

　　5. The sealing performance of laser welding during the assembly process is poor, and air leaks when measuring air leakage;

　　6. Dust and pole piece dust can easily cause micro short circuits first;

　　7. The positive and negative electrode plates are thicker than the process range and difficult to insert into the shell;

　　8. Liquid injection sealing problem, poor sealing performance of steel balls leads to air bulging;

　　9. The incoming shell material has a thicker shell wall, and the deformation of the shell affects the thickness;

　　10. Excessive external ambient temperature is also the main reason for the explosion of lithium battery packs.
