As we all know, there are many types of batteries, but not every lithium battery manufacturer will explode due to extrusion or puncture.
Liquid batteries, as the name suggests, use a liquid electrolyte. The positive and negative electrodes of this battery are separated by a separator to avoid direct contact between the positive and negative electrodes.
If the battery is punctured and squeezed, the separator may be broken, resulting in a short circuit between the positive and negative electrodes, which in turn generates heat and generates a large amount of gas, and the battery will begin to swell.
▲ Battery structure
It should be known that the liquid electrolyte in the battery is very active and burns easily. After piercing the casing, the electrolyte contacts the air at high temperature, and then it will emit smoke and sparks, and it will indeed burn fiercely.
Even a relatively safe lithium battery is very dangerous after being punctured, so it's okay not to get a sharp object on the lithium battery. Of course, please try not to poke other batteries.
What other deadly operations for the battery?
There are still many types of batteries commonly used in our lives. Primary batteries (ie, non-rechargeable) include carbon batteries, alkaline batteries, and secondary batteries include nickel-metal hydride batteries, nickel-cadmium batteries, and lithium batteries.
Primary battery (non-rechargeable)
For primary batteries, although they do not necessarily explode when they are penetrated, the potassium hydroxide electrolyte in alkaline batteries (zinc-manganese batteries) is strongly alkaline, and contact with them may cause burns.
In addition, before everyone used carbon batteries to run out of power, they used teeth to bite, shake, and bask in the sun, and then the battery would have some residual power. It is not suitable for common alkaline zinc-manganese batteries. So replace the battery when it runs out. Don't toss the lithium battery manufacturer.
▲ Do not try to charge the battery once
Finally, the primary battery cannot be charged. This is not the title of the title, but it is dangerous to charge the primary battery. For example, alkaline batteries can easily be short-circuited during charging, causing the battery to overheat or cause leakage. Liquid, so do n’t try it, and pay attention to the classification when storing the battery.
Battery (rechargeable)
Compared with the primary battery, the danger of the secondary battery is still greater. When using it, pay more attention not to be stupid, such as teeth biting behavior, or piercing the battery, squeezing the battery to cause deformation, exposure, overcharge and over discharge Etc. are unscientific.
If you encounter a battery pack in a mobile device, do not try to remove or repair it yourself, do not puncture the battery outsourcing, and leave it to an experienced person to deal with the lithium battery manufacturer.
▲ Don't break the soft case of the battery drum kit
Although the mainstream lithium battery has no memory, it can be used with charging, but still be careful to avoid overcharging and overdischarging, and try not to charge when sleeping.
