01 but hits: how to prevent the blowout of lithium battery?
All of the lithium battery blasting are caused by the fever caused by short circuit batteries, the cause of the short circuit have overcharge, over discharge, directly connected to the positive and negative electrode, electrolyte leakage, etc.
Therefore, when designing the lithium battery, we can begin from the following points: 1.
To prevent the battery overcharge for more than 4.
2v;
2.
Ban battery in 2.
Below 75 v;
3.
The explosion-proof valve installed on the metal shell;
4.
To prevent short circuit in the process.
Of course, the best way is to design a battery maintenance circuit board.
Although this will increase the cost of production of lithium-ion batteries, but it is necessary for the safe use of lithium-ion batteries, all normal lithium battery manufacturer's products are not immune to this design.
Lithium-ion polymer battery will explode?
Polymer lithium battery is made from soft packing and polymer electrolyte of lithium battery products, normal use, store not burst, unless man-made strong short circuit damage.
In order to reduce the explosion accidents, polymer lithium-ion batteries have been applied in more and more situations.
Although the lithium battery is still in the process of replacement for other types of batteries, but lithium polymer battery has started in some categories of lithium battery type for ordinary lithium batteries.
