18650 battery 3.7v 2200mah

　　What is the reason for bulging 18650 battery 3.7v 2200mah?

　　1. The problem with the manufacturing level of lithium-ion battery packs is that the electrode coating is uneven and the production process is uneven.

　　2. The short reflection of the short circuit fault is converted into a large amount of heat, causing the electrolyte solution to dissolve and vaporize, causing lithium ions;

　　3. In addition, if the battery pack of the lithium iron phosphate battery pack is not used for a long time, the bulging phenomenon will also occur. Because the gas is conductive to a certain extent, the discharge time is equal to the direct contact between the positive and negative of the rechargeable battery.

　　4. The 18650 battery 3.7v 2200mah charger is of poor quality. The charging head is made of fake or defective electronic devices, which cause high heat, inaccurate main parameters and inability to control the battery charge limiter.

　　5. The battery charging time is too long. If the battery is charged too much, a large amount of steam will flush the electrode, causing the 18650 battery 3.7v 2200mah in the active material to fall off, reducing the number of battery cycles, accelerating the water shortage rate of the rechargeable battery, endangering the dissolution of the 18650 battery 3.7v 2200mah, causing the battery temperature to rise, making it full Drum shape!

　　What are the types of lithium-ion battery separators?

　　The structure and composition of electric diaphragms can be divided into different types, with three key factors currently on the market. Porous structure polymer membrane: Lithium-ion batteries with uniform porosity were prepared using mechanical equipment, thermal chromatography, impregnation ion exchange and other methods.

　　Non-Protective Cloth Membrane: Consists of a fixed item or any chemical fiber, usually made of organic compounds or porcelain. Inorganic compound bags: Most lithium ions are made of inorganic nanoparticles and their polymer composites.

　　During this period of rapid development of the lithium-ion sales market, lithium-ion battery membranes, as the key to the lithium-ion industry, have relatively broad market prospects, and their production and manufacturing technology strength will be improved.
