In order to prevent the battery from discharging or overcharging due to misuse, a triple protection mechanism is installed in the single lithium-ion battery.
First, install a relief valve (i.e. the vent hole on the top of the battery). When the internal pressure of the battery reaches a certain value, the safety valve will automatically open to guarantee. battery safety;
Secondly, it is about choosing the appropriate separation material. When the temperature reaches a certain value, the micron-sized pores on the separator automatically dissolve, so that lithium ions cannot pass through. through and the internal reaction of the battery will stop;
The third is the use of switching elements, when the temperature inside the battery increases, its resistance increases accordingly. When the temperature is veryop high, the power supply will be interrupted. automatically stopped.
Many people think that as long as we use lithium batteries correctly when using electronic products such as portable speakers, that is enough. However, with so many users, it is inevitable that improper use of lithium batteries will cause. unnecessary damage. Therefore, lithium batteries have the above three protection mechanisms to solve the problem of battery overdischarge or overcharge.
