What are 18650 batteries?

The 18650 Lithium-Ion battery is a rechargeable battery commonly used in power tools, garden tools, vacuum cleaners, electric two-wheelers, etc. It can be charged without removing the battery from the device.

During the charging process of the 18650 battery, under the action of an external electric field, lithium ions are transferred from the positive electrode to the negative electrode from the inside of the battery. The current flows from the negative to the positive electrode through the external circuit. The interior remains electrically neutral (the electrons flow from the positive electrode to the negative electrode through the external circuit). The discharge process is the opposite. Lithium ions and electrons return from the negative electrode to the positive electrode, and the external circuit current flows from the positive electrode to the negative electrode.

The advantages of 18650 batteries

The 18650 Li-Ion battery is one of the most popular batteries on the market today. They are used in a wide variety of applications, from powering electronic equipment to emergency backup power. Additionally, 18650 batteries have many advantages over other types of batteries, making them an excellent choice for a variety of needs.

One of the biggest advantages of the 18650 lithium-ion battery is its high energy density. This means they can store more energy than other types of batteries, making them ideal for applications that require an extended operation.

Another advantage of 18650 batteries is their high discharge rate. This means they can provide a lot of power very quickly, making them ideal for use in devices that require rapid bursts of power, such as digital cameras or video lights.

18650 lithium-ion batteries are also very rugged and durable, making them resistant to damage from being dropped or knocked around.

The 18650 lithium battery has high safety. To preven a short circuit of the battery, the positive and negative electrodes of the 18650 lithium battery are separated.

Overall, 18650 lithium-ion batteries offer a great combination of high energy density, high rate discharge, and durability. Choose EVE to bring you a different experience!
