What is Li-ion 18650 Battery?

Li-ion 18650 battery is a cylindrical rechargeable lithium-ion battery. The 18650 in its name refers to its size, which is 18mm in diameter and 65mm in length.

Generally speaking, the standard voltage of Li-ion 18650 battery is 3.6V and 3.7V, and the standard capacity is 1200-3500mAh. However, by connecting multiple Li-ion 18650 batteries in series and parallel, a battery pack can be formed, so that the Li-ion 18650 battery can obtain a higher voltage and capacity.

Working Principle Of Li-ion 18650 Battery

The working principle of Li-ion 18650 battery can be summarized as the continuous movement of lithium ions between the positive and negative electrodes of the battery, thereby generating current.

Charging process of Li-ion 18650 battery:

When the Li-ion 18650 battery is connected to the power supply, lithium ions will move from the positive electrode to the negative electrode through the electrolyte. At the same time, electrons will flow from the negative electrode to the positive electrode, so that the whole process reaches charge balance.

Discharging process of Li-ion 18650 battery:

When the Li-ion 18650 battery powers the device, lithium ions will move from the negative electrode to the positive electrode through the electrolyte. At the same time, electrons will flow from the positive electrode to the negative electrode, forming a current.
