Will the button battery explode if it is short-circuited?

Because of their small size, button batteries have been widely used in various miniature electronic products, ranging from 4.8mm to 30mm in diameter and 1.0mm to 7.7mm in thickness; they are generally used as backup power supplies for various electronic products, such as Computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, electric toys, cardiac pacemakers, electronic hearing aids, counters, cameras, etc.; button batteries are also divided into two categories: chemical batteries and physical batteries, with chemical batteries being the most used universal. They are composed of anode (positive electrode), cathode (negative electrode) and its electrolyte. As shown on the right. Its appearance is made of stainless steel and used as a positive electrode. Its negative electrode is a stainless steel circular cover. There is a sealing ring between the positive electrode and the negative electrode for insulation. The sealing ring is made of nylon. The sealing ring can prevent electrolyte leakage in addition to insulating purposes . There are many types of button batteries, most of which are named after the materials used, such as silver oxide batteries, lithium ion batteries, and alkaline manganese batteries. The reason for the battery explosion is that the battery is too large, causing internal heat expansion and electrolyte vaporization. At this stage, the battery will bulge and deform. If the battery is a metal-sealed shell, the shell may be broken to release energy and explode. The flammable gas volatilized in the ignition battery causes a secondary explosion. The prerequisite for explosion is that the battery itself must have enough power and small enough internal resistance. A short-circuit of a battery with a small capacity will only heat up and cannot explode. A battery with a large internal resistance does not even generate heat and is less likely to explode. Lithium-ion batteries are generally used with a protection board, so they will be protected after a short circuit and will not explode. If it is a bare battery, the possibility of explosion below 1000mAH is very small. Lead-acid batteries are divided into fully enclosed and open type. The open type will explode except for sparks when charging. The short circuit will not explode, and it is more likely that the pole will be blown. The fully enclosed gel battery has a large internal resistance and the short circuit will quickly bulge.
