Why do customized lithium batteries come with protective plates?

　　When customers customize lithium batteries, they will require the addition of protective plates. Generally, if the customer does not specifically mention it, we will also guide them to add protective plates. Do I have to add a protective plate to make this lithium battery? The reason why secondary lithium-ion batteries need protection is determined by their natural color characteristics.

　　The material of the lithium battery itself determines that it cannot be overcharged (overcharged lithium batteries are prone to explosion risk), over discharged (overcharged lithium batteries are prone to damage the battery cell, cause the battery cell to fail, and cause the battery cell to be scrapped), over current (overcharged lithium batteries are prone to increase the battery cell temperature, shorten the battery cell life, and in serious cases, internal Thermal runaway causes the battery cell to explode) Short circuit (short circuit of lithium battery will easily make the cell temperature higher, causing Thermal runaway inside the cell, leading to cell explosion) and ultra-high temperature charging and discharging, so the lithium battery pack will always follow a delicate protective plate and a current protector.

　　The main function of the protection board is to protect the battery cells. When the battery voltage exceeds 4.2 V, the battery cells will experience side effects. So, what is the role of a lithium battery protection board? How to better protect customized lithium batteries? Lithium batteries are generally composed of battery cells, protective plates, shells, and auxiliary materials. Widely used in electric forklifts, electric bicycles and motorcycles, drones, unmanned ships, communication base stations and photovoltaic energy storage, as well as medical equipment.
