18650 batteries are widely used in various portable electronic devices, such as laptops, smartphones, flashlights, electric tools, and electric vehicles.
Compared with other batteries, they have advantages such as high energy density, long lifespan, low self discharge rate, low cost, and good performance stability.
The 18650 battery mainly consists of three parts: positive electrode, negative electrode, and electrolyte.
The positive electrode is usually composed of oxide materials such as lithium manganate, nickel cobalt lithium manganate, ternary materials, etc. The negative electrode is composed of carbon materials such as graphite, Graphene, etc. The electrolyte is composed of organic solvents and salts.
Although 18650 batteries have many advantages, they also need to pay attention to safety issues. If used or handled improperly, 18650 batteries may cause harm to people's bodies and even endanger their lives. Therefore, when using 18650 batteries, it is important to follow the correct usage and handling methods.
