Why does the battery burst?

Cell phones and notebook computers use lithium batteries, which are commonly referred to as lithium batteries. Batteries generally use materials containing lithium as electrodes. To put it simply, the negative electrode is used to store positively charged ions, and the positive electrode is used to store negatively charged ions. During the charging process, lithium ions will move from the negative electrode to the positive electrode. When the battery is working, the lithium ions will move in the opposite direction. The north and south poles of the battery should never touch each other. Therefore, battery manufacturers will place a barrier between the north and south poles. If the barrier breaks under the influence of external factors and other factors, all the energy in the battery will flow to the electrolyte instead of the north and south. Electrolyte (the electrolyte is the carrier of ion transmission in lithium batteries). The electrolyte itself is an unstable chemical substance. After receiving too much energy and touching the outside world, it will generate a lot of heat and even burst into flames.
