What is a battery explosion? How to prevent lithium battery from exploding?

What is a battery explosion? The national standard stipulates that any part of the solid matter in the battery is discharged instantaneously, and it is called an explosion if it is pushed to a distance of more than 25cm from the lithium battery. The method of identification in the experiment is to cover the test battery with a circular mesh so that the battery is at the center of the circle, that is, 25 cm from either side of the mesh cover. If no solid part passes through the mesh cover in the experiment, it proves that the battery has not exploded. Here are specific instructions for the net: the net wire adopts a soft aluminum wire with a diameter of 0.25mm, and the density of the net is 6-7 pieces/cm. How to prevent lithium battery explosion? All lithium battery explosions are caused by battery heating caused by short circuits. The causes of short circuits include overcharging, overdischarging, direct connection of positive and negative electrodes, and electrolyte leakage. Therefore, in the design of lithium batteries, the following points can be started: 1. It is forbidden to overcharge the battery above 4.2V; 2. It is forbidden to overdischarge the battery below 2.75V; 3. Install an explosion-proof valve on the metal shell; 4. Process Prevent short circuit during the process.
