I believe you often see lithium battery explosion on the news, but do you know what causes lithium ion battery explosion? Let me explain it to you.
(1) External short circuit: refers to the external short circuit of the battery, including the short circuit caused by poor insulation design inside the lithium-ion battery pack and other factors. It can also be caused by improper operation. If the external circuit of the battery is short and the electronic components do not cut off the circuit, the large discharge of the lithium-ion battery will cause the temperature of the battery to rise. The excessive temperature will damage or directly damage the diaphragm inside the battery, which will cause the internal short circuit and lead to the explosion we are most worried about
(2) Internal short circuit: once internal short circuit occurs, the battery unit of the lithium-ion battery pack will release a large amount of current, generate a large amount of heat energy, and form a large amount of gas inside, resulting in excessive internal pressure of the power lithium-ion battery. When the pressure reaches the degree that the battery shell cannot bear, explosion will occur
(3) Overcharge: When the battery unit is overcharged, lithium in the positive electrode may be excessively released, resulting in changes in battery structure. The lithium in the negative electrode is not inserted into the negative electrode, which also causes lithium to precipitate on the surface. When the voltage reaches above 4.5V, the electrolyte breaks down and produces a large amount of gas. Overcharging may cause dangerous situations such as liquid leakage, deformation, and fire. Severe enough to cause an explosion!
