Safety issues of lithium batteries
Any lithium battery with quality issues or improper use may pose safety hazards and even cause fires and explosions.
The biggest hidden danger of lithium batteries is that in the case of overcharging, lithium ions accumulate in the negative electrode to form dendrites, pierce the separator, form internal short circuits, generate high currents, cause an increase in internal temperature, and generate gas in the electrolyte, leading to an increase in internal pressure and causing leakage, fire or expansion explosion.
Therefore, choosing good lithium battery products is very important, and considering the application situation appropriately can completely eliminate safety hazards. Focus on analyzing the safety factors of lithium batteries and what issues should be noted when selecting and using lithium batteries
Safety factors:
a. Material factors
Choose safe positive, negative, electrolyte, and separator materials, strictly control the process flow and process parameters.
b. Explosion proof valve
When the internal pressure or temperature reaches the preset value, open the explosion-proof valve to release excess gas and ensure safety.
c. protection circuit
Protection circuits can effectively prevent overcharging, overdischarging, overcurrent, etc. Reasonable and reliable protection circuits and systems are important guarantees.
matters needing attention:
a. To choose batteries of reliable quality and brand, so that battery materials and processes can be effectively guaranteed.
b. Lithium batteries must have a protection system. Lithium batteries without a protection system are prohibited from use. In addition, the rationality of the protection system design and reliable testing of the protection system are important. It is necessary to choose lithium battery products from factories that understand battery management and have experience in lithium battery management.
c. We should also pay attention to keeping lithium batteries away from sources of fire and high temperature environments, and try to avoid system short circuits or overcharging and discharging.
If you choose batteries from reputable manufacturers with good protection systems, the probability of lithium batteries catching fire or exploding is very, very low.
