The charging and discharging principle of 18650 battery

The charging and discharging principle of 18650 battery

Page view
18650 battery life theory is 1000 cycles of charging. Because of the large capacity per unit density, most of them are used in laptop batteries. In addition, because the 18650 battery has a very good stability during work.

18650 battery life theory is 1000 cycles of charging. Because of the large capacity per unit density, most of them are used in laptop batteries. In addition, because the 18650 battery has a very good stability during work, the 18650 battery is widely used in various electronic fields: often used in high-end bright light Flashlights, portable power supplies, wireless data transmitters, electric thermal clothing, shoes, portable instruments, portable lighting equipment, portable printers, industrial instruments, medical instruments, etc.

The working principle of 18650 battery refers to its charging and discharging principle. When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. The carbon as the negative electrode has a layered structure. It has many micropores. The lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer. The more lithium ions are inserted, the higher the charging capacity.
The 18650 battery manufacturer tells you that when the battery is discharged (that is, the process of using the battery), the lithium ions embedded in the carbon layer of the negative electrode are released and move back to the positive electrode. The more lithium ions returned to the positive electrode, the higher the discharge capacity. What we usually call battery capacity refers to the discharge capacity.
The manufacturer of the 18650 battery tells you that during the charging and discharging process of the lithium ion battery, the lithium ion is in a state of movement from the positive electrode to the negative electrode to the positive electrode. If we compare the 18650 battery to a rocking chair, the two ends of the rocking chair are the two poles of the battery, and the lithium ion is like an excellent athlete running back and forth on both ends of the rocking chair. Therefore, the experts gave the lithium-ion battery a lovely name, rocking chair battery.
