The working principle and process of lithium battery -Lithium - Ion Battery Equipment
1. The working principle of lithium-ion battery
As we all know, lithium-ion batteries use lithium cobalt oxide as the anode and carbon as the cathode. Lithium-ion batteries work by charging and discharging. When the battery is charged, lithium ions are formed at the positive electrode of the battery, and the lithium ions pass through the electrolyte to the negative electrode. Negative carbon has a layered structure with many micropores. Lithium ions reaching the negative electrode are embedded in the micropores of the carbon layer. The more lithium ions are intercalated, the greater the charging capacity. In the same way, when the battery is discharged (the process we use the battery), the lithium ions embedded in the carbon of the negative electrode come out and go back to the positive electrode. The more lithium ions return to the positive electrode, the greater the discharge capacity. The battery capacity we usually refer to is the discharge capacity.(Lithium - Ion Battery Equipment)
It is not difficult to see that during the charging and discharging process of a lithium ion battery, the lithium ions are in a state of motion from the positive electrode to the negative electrode and then to the positive electrode. If we compare the lithium-ion 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 a good athlete, moving back and forth between the two ends of the rocking chair. Hence, experts have given lithium-ion batteries an endearing name: rocking chair batteries.
2. Assembly process of lithium-ion battery
Lithium-ion battery technology is very strict and complex, and only a few important processes can be briefly introduced here.
(1) Pulping: Mix the active substance powder with special solvent and binder, and stir evenly at high speed.
(2) Coating: The slurry is uniformly coated on the surface of the metal foil, and dried to form a positive electrode sheet and a negative electrode sheet.
(3) Assembly: Arrange the positive plate diaphragm and the negative plate diaphragm in the order from top to bottom, make the battery core by winding, and then inject electrolyte, sealing and other processes to complete the battery assembly process and make the finished battery.
(4) Transformation: Use special battery charging and discharging equipment to conduct charge and discharge tests on finished batteries, test each battery, screen qualified finished batteries, and wait for delivery.
