What are the battery materials? What is the cause of the explosion of the battery

What are the battery materials? Carbon anode materials: The anode materials actually used in lithium-ion batteries are basically carbon materials, such as artificial graphite, graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, and pyrolytic resin carbon. Tin-based anode materials: can be divided into tin oxides and tin-based composite oxides. Oxide refers to the oxide of tin metal in various valence states. There are no commercial products. Nitrides: There are no commercial products either. Alloys: Including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys, and there are no commercial products. Nano-level: carbon nanotubes, nano-alloy materials. Nano-oxide: According to the market development trend of the new energy industry of lithium-ion batteries in 2009, many companies have begun to use nano-titanium oxide and nano-silicon oxide to add to the traditional graphite, tin oxide, and carbon nanotubes to improve lithium ion The amount of charge and discharge of the battery and the number of times of charge and discharge. There are many types of batteries on the market, but we found that some of them will explode during use. The reasons are: 1. The internal polarization is relatively large. 2. The pole piece absorbs water and reacts with the electrolyte. 3. The quality and performance of the electrolyte itself. 4. The injection volume cannot meet the technological requirements during injection. 5. In the assembly process, laser welding has poor sealing performance, air leakage, leak detection, etc. 6. Dust, pole piece dust is likely to cause micro short circuit first... 7. The positive and negative plates are thicker than the process range, and it is difficult to enter the shell. 8. The problem of liquid injection sealing, poor sealing performance of the steel ball leads to air bulging. 9. The shell wall is too thick in the incoming shell material, and the shell deformation affects the thickness. 10. The product itself has large quality problems.
