Explosion-proof requirements of nickel-cadmium batteries, explosion-proof principles of nickel-cadmium batteries. Lithium batteries have become the battery of choice for portable electronic products, but they have always hidden the danger of explosion. As more and more applications are used, explosion events will emerge one after another. In fact, through the correct battery system design and battery level judgment, lithium batteries can be very safe. At present, explosion-proof lines and explosion-proof cell technology are mature, and there should be fewer and fewer explosions.

Lithium battery explosion-proof requirements

1. There is a protection device to prevent the battery temperature is too high and the battery is damaged;

2. When the single cell or battery pack is allowed to charge in the flameproof enclosure, the battery should be provided with a protection circuit to prevent overcharging;

3. Faulty batteries and waste batteries must be placed in a special treatment cabinet for isolation and disposal, and it is recommended to use explosion-proof sand buckets to handle accident batteries;

4. When charging the lithium battery, you must set the upper voltage limit to take into account the battery life, capacity, and safety. The upper limit of the ideal charging voltage is 4.2V;

5. When designing a lithium battery system, two electronic protections must be provided for overcharge, overdischarge, and overcurrent. The protection plate is the second protection. Remove the protection plate and charge it. If the battery will explode, it represents the design bad.
