18650 lithium 3.7 battery

  18650 lithium 3.7 battery protection board principle

  18650 lithium 3.7 battery protection board is mainly an integrated circuit board that protects rechargeable (generally lithium batteries). The reason why lithium batteries need protection is determined by its own characteristics. Since the material of the 18650 lithium 3.7 battery itself determines that it cannot be overcharged, overdischarged, overcurrent, short-circuited, or charged and discharged at ultra-high temperatures, the 18650 lithium 3.7 battery components will always appear with a delicate protective board and a current fuse.

  Due to the chemical characteristics of lithium batteries, during normal use, chemical positive reactions in which electrical energy and chemical energy are converted into each other occur internally. However, under certain conditions, such as overcharging, overdischarging and overcurrent will cause internal damage to the battery. A chemical side reaction occurs. When the side reaction intensifies, it will seriously affect the performance and service life of the battery, and may produce a large amount of gas, causing the internal pressure of the battery to rapidly increase and then explode, causing safety issues.

  Therefore, all lithium batteries require a protection circuit to effectively monitor the charging and discharging status of the battery, and to shut down the charging and discharging circuit under certain conditions to prevent damage to the battery.
