As a professional Lithium Battery Pack Supplier, today we give a brief introdction of the working principle of Lithium Batteries. When the battery is charged, lithium ions are formed on the positive electrode of the battery, and the resulting lithium ions move from the electrolyte to the negative electrode. As a negative carbon, it has a layered structure. It has many microholes. When reaching the negative electrode, lithium ions are embedded in the microholes of the carbon layer. The more lithium ions are embedded, the higher the charge capacity is.
By the same token, when the battery is discharged (that is, when we use the battery), the lithium ions embedded in the negative carbon layer are removed and then moved back to the positive electrode. The more lithium ions back to the positive electrode, the higher the discharge capacity. What we usually mean by battery capacity is the discharge capacity.
