What is the 18650 lithium battery charging and discharge principle?

  The working principle of the lithium ion battery refers to the principle of charging and discharge. When the battery is charged, the battery is generated on the positive electrode of the battery, and the generated lithium ion is moved to the negative electrode through the electrolyte.

  As a layered structure of the negative electrode, it has a lot of micropores. The lithium ion that reaches the negative electrode is embedded in the carbon layer micropores. The more lithium ion is embedded, the higher the charging capacity.

  In the same way, when the battery is discharged (that is, the process of using the battery) is taken out of the lithium ion embedded in the negative carbon layer, and the exercise returns to the positive electrode. The higher the lithium ion returns to the positive pole, the higher the discharge capacity. The battery capacity refers to the discharge capacity.

  It is not difficult to see that during the charging and discharge of lithium ion batteries, lithium ions are in the motion state of the positive electrode → negative electrode → the ahead. If we compare the lithium ion battery to a rocking chair, the ends of the rock chair are the poles of the battery, and the lithium ion is like an excellent sportsman, running back and forth at both ends of the rock chair. Therefore, the experts gave a lovely name rocking chair battery for lithium ion batteries.
