Decomposition of Causes of Explosion and Combustion of Lithium Batteries.lithium ion solar energy storage system battery

release time:2023-10-07 Hits:     Popular:AG11 battery

  

  1. Internal short circuit (mostly large units of soft packaging): Structural or process defects leading to insertion of pole ears, insufficient excess of diaphragm wrapping, burrs, diaphragm folding, etc. Pole ear insertion often occurs in structures with thick batteries and parallel connections, where the insulation of the pole ear position is not in place, which can easily lead to internal acute short circuits and combustion or explosion during subsequent product installation or use (internal short circuits: I have a deep understanding of this point. At that time, more than 2K of this type of battery was scrapped, which is actually a design defect - the essence of the abnormality is: internal acute short circuits). However, this situation is almost rare now, Unless there are external factors.

  2. External short circuit: Explosion after combustion caused by external short circuit of batteries below 1AH is rare, usually resulting in bulging or simply burning the ear. Personal analysis has shown that combustion is caused by external short circuit of power batteries or large capacity mobile phone batteries. This involves improper use by customers - when installing metal outer boxes without considering pole ear insulation, abnormal smoke and combustion of the battery may occur at the installation site; Insufficient structural fixing measures are also common in power batteries (due to inadequate consideration). During user use, shaking of the battery pack can cause damage to the external insulation protection film or connecting wire skin of the battery, ultimately leading to short circuit combustion.

  3. Overcharging explosion: This is the most dangerous and feared by enterprises, but it still occasionally occurs. From our understanding, there are two points: a. Users do not use matching chargers according to requirements, which damages the protection circuit. Users often charge for an unlimited time, which is difficult to avoid; b. The battery configuration is unreasonable and the protective board fails, which can also cause a complete explosion The same applies to a single battery.

  4. The material of the battery itself is not up to standard. If the material is not qualified, it may overheat under the calibrated voltage and current, leading to accidents.
