Will using 18650 batteries explode.

The explosion of 18650 batteries has always been a concern for everyone. After 30 years of development, the preparation process of 18650 batteries has become very mature. In addition to greatly improving performance, its safety is also very perfect. But you should know that many of these incidents are actually caused by inferior and unqualified batteries. Many friends believe that the explosive power of the cylindrical 18650 lithium-ion battery with a metal shell is beyond your imagination. In fact, this metal shell lithium-ion 18650 battery cell has a cap on the positive end, and the cap is equipped with a gas release valve device. Before the gas inside reaches the explosive threshold, it will already release gas. The safety valve is a standard feature of every 18650 lithium-ion battery and the most important explosion-proof barrier.. Of course, this belongs to the brand. The reason for the explosion of 18650 lithium-ion batteries is that the electrolyte and trace amounts of water inside are subjected to high temperature and pressure for a short period of time, causing expansion and explosion. With a gas release valve, this condition will not occur. Unless there is an internal short circuit that can create explosive conditions.

The previous incidents of mobile power bank explosions were all caused by unscrupulous manufacturers using substandard 18650 batteries or even second-hand waste electricity to save costs. At present, the 18650 lithium-ion batteries produced by major battery manufacturers are actually very safe, and the usage rate of 18650 batteries is very high. We can use them correctly and avoid battery short circuits, damage, or high temperatures in daily use, without worrying about the battery exploding. We cannot use a single bamboo pole to knock over a boat of people and determine the safety of 18650 lithium-ion batteries based on individual inferior products.

Sometimes it is also necessary to test the comprehensive mechanical performance of lithium batteries. If the pass rate of the tested battery meets the standard, it can be shipped. There is a certain level of danger involved in conducting these experiments, as experiments such as heavy hammer strikes can cause individual batteries to explode, completely shattering the steel shell. This is not the case of opening the lid, but rather blowing the steel shell into pieces. The power is quite strong. This experiment is conducted inside an iron box. When the battery explodes, the entire iron box will vibrate and shake. The experimental cabinet weighs at least a hundred pounds, and you can imagine the power of the explosion.
