Why do poor-quality laptop battery explosion
There are many factors cause the poor-quality laptop Li-ion battery explosion, but the principle is because of batteries produce large amounts of heat caused high temperature and high pressure which lead the Laptop battery to fire and explosion. Common reason of the explosion caused by the following categories:
1. Heating caused batteries decomposition, combustion, and explosion. The explosion temperature varies due to the battery components, such as batteries with LiCoO4 ingredients heated to 165 ℃ 45 minutes may explode (belonging to more heat-resistant). Although usually it’s difficult to put the Dell FK890 battery heated to such temperatures, but usually in use still have to be careful not to put the battery in a place near heat sources, such as a closed car under the sun exposure and close to the engine, do not close to the fire source either.
2. Overcharge caused the explosion. If charge the battery with an unqualified charger, while the battery protection chip failure, when the charging voltage exceeds 4.5V, if the negative electrode capacity of poor Lithium, lithium-ion batteries will be deposited to make internal short-circuit; if negative Lithium capacity is relatively strong, then the solvent is rapidly oxidized to produce a lot of heat so that the hp PB994A battery temperature get higher and lead to more reactions and emit more heat. If the charging current is large, and the stability of the batteries is also very poor, batteries temperature rise rapidly, the battery will be fire, explosion. So, the friends who buy some cheap, non brand lithium batteries had better pay attention, you can ensure that your battery protection chip works? When the VGP-BPS2C battery charge, and if you feel unusual heat you should decisively handle that.
