Any lithium-ion battery can be a safety hazard or even burst into flames if the product is of questionable quality or is improperly used.
The biggest hidden danger of lithium battery is that in the case of overcharge, lithium ions accumulate in the negative electrode to form dendrites, piercing the diaphragm, forming an internal short circuit, generating a large current leading to internal temperature rise, electrolyte gas resulting in internal pressure rise, resulting in leakage fire or expansion explosion.
Therefore, the choice of good lithium battery products is very important, and the proper consideration of the application is completely able to eliminate potential safety risks. Focus on the analysis of lithium battery safety factors and the choice and use of lithium battery should pay attention to what problems
Safety factors:
A. Material factors
Select safe cathode, cathode, electrolyte, and diaphragm materials, and strictly control the process flow and process parameters.
B. the valve
When the internal pressure or temperature reaches the preset value, open the explosion-proof valve to release excess gas to ensure safety.
C. Protection circuit
Protection circuits can effectively prevent overcharge, over-discharge, over-current, etc. Reasonable and reliable protection circuit and the system is an important guarantee.
Notes:
A. To choose reliable quality and brand battery, so that the battery material and process can be effectively guaranteed.
B. The lithium battery must have a protection system, and the lithium battery without a protection system is prohibited to use. In addition, the rationality of the protection system design and the reliable test of the protection system is very important.
C. We should also pay attention to the use of lithium batteries, as far as possible to keep away from the fire source and high-temperature environment, as far as possible to avoid system short circuit or overcharge and discharge.
If you choose a regular manufacturer's cell and a good protection system, the probability of lithium battery fire or explosion is very, very low.
