18650 cylindrical lithium battery is a common lithium-ion battery with the advantages of high energy density, long life, small self-discharge rate, low internal resistance, and high discharge platform. With the increasing demand for new energy industries and portable devices, lithium batteries have gradually become the first choice. Among many lithium batteries, 18650 cylindrical lithium batteries are widely used in the following fields because of their high energy density, safety, cost-effectiveness and other characteristics:

The advantage of new energy vehicles is that they are more low-carbon and environmentally friendly than gasoline-fueled vehicles. It uses unconventional vehicle fuels as its power source, such as lithium batteries, hydrogen fuel, etc. Lithium-ion batteries are also used in a wide range of applications, including new energy vehicles, mobile phones, laptops, tablets, mobile power supplies, electric bicycles, power tools, etc.

Among the safety requirements for lithium batteries, safety standards for charging and discharging operations and electricity consumption are crucial. These standards are designed to ensure the safety and reliability of the operation process and prevent accidents. The following are the main safety standards regarding lithium battery charging and discharging operations and electricity use:

Due to its large capacity per unit density, 18650 lithium batteries are mostly used in laptop batteries. In addition, 18650 lithium batteries have very good stability at work and are widely used in various electronic fields: often used in high-end strong light Flashlights, portable power supplies, wireless data transmitters, electric thermal clothing and shoes, portable instruments, portable lighting equipment, portable printers, industrial instruments, medical instruments, etc.

Ternary lithium battery is a lithium-ion battery. Its positive electrode material is mainly composed of lithium nickel cobalt manganese oxide, and its negative electrode is composed of graphite or other carbon materials. Ternary lithium batteries are popular due to their high energy density, long cycle life and high safety performance, and therefore are widely used in electric vehicles, portable electronic devices, energy storage systems and other fields.

Battery protection boards are designed to protect batteries. But many people do not understand the specific functions of these protection boards. The following is a discussion of the functions of battery protection boards.
