Do lithium iron phosphate batteries explode?
Dec 16,2021 | Power Station Battery
The lithium iron phosphate battery will not burst into flames under normal circumstances. Lithium iron phosphate batteries are safe in normal use, but they can be dangerous in extreme cases. This has a lot to do with the company's material selection, ratio, process and later use.
First, the lithium iron phosphate battery starts to overheat, due to short circuit, rapid discharge, overcharge, manufacturing defects, poor design or mechanical damage, etc. Overheating can lead to the initiation of a "thermal runaway" process, which is an exothermic reaction inside the battery that causes the temperature and pressure inside the battery to rise at a rapid rate, wasting energy. Once a cell goes into thermal runaway, it generates enough heat to cause neighboring cells to go into thermal runaway as well. As each cell breaks up in turn and releases its contents, a flame burns over and over again. This causes the flammable electrolyte in the battery to leak, and if a disposable lithium-ion battery is used, the combustible lithium metal can be released.
Another is caused by the external environment, for example, the external environment temperature is too high, or the temperature control system is faulty, the heat is too high to disperse will also lead to fire.
We know that whether it is driving, charging, or collision, it is possible to cause the lithium ion iron phosphate battery fire. Although these three states are different, but there is a common point, that is to cause the heat loss of the battery, overheating is bound to fire.
2.Lithium batteries cause fires
- Reason one: high temperature use
Avoid using in harsh conditions, such as high temperature, high humidity, long-term exposure to the sun in summer, etc. Do not place the battery in an area with open fire or high temperature, which may shorten the service life of the battery at best, or cause fire or explosion at worst.
- reasontwo: Overcharging
Overcharging can cause the battery to heat up, swell and even explode. Therefore, the charging time can not be too long, on many batteries that have been used for 1 to 2 years, charging should be particularly careful.
- Reason 3: private wire
The fire was also caused by a short circuit caused by the disorderly pulling of wires in the residential area. Wires in the air without any support and protection measures, leakage probability is very high. In addition, the simultaneous use of too many high-power electrical appliances on a plug board is also easy to cause a short circuit, causing a fire.
Lithium iron phosphate batteries are safe on a large scale. A large number of lithium battery explosions and fires occur in ternary lithium batteries rather than lithium iron phosphate batteries. But when internal or external causes of battery damage, lithium iron phosphate battery will also initiate flammable and explosive. As long as there is reasonable use at ordinary times, try to prevent abuse, reduce the probability of harmful events, the battery will work safely and reliably.
Under the current technical background, lithium batteries have achieved certain development outcomes in recent years, under the concept of sustainable development, to meet the objective of energy savings and emission reduction. With increased investment in technological research and development, it is certain to usher in brand new development in the future.
