Structure and Characteristics of 18650 Cylindrical Lithium Battery
18650 cylindrical lithium battery is a common lithium-ion battery, its size is 18 mm in diameter and 65 mm in length, so the name 18650. This kind of battery has a large capacity and is usually widely used in power tools, portable electronic equipment, electric bicycles and other fields.
The positive electrode of the 18650 lithium battery usually uses lithium cobaltate, lithium manganate, lithium iron phosphate and other chemical materials, and the negative electrode is composed of carbon materials, and the diaphragm is usually made of excellent plastic polymer materials.
The 18650 cylindrical lithium battery is characterized by high energy density, long life, low self-discharge, fast charging, and good safety and adaptability, so it is widely used in power tools, electric vehicles, portable electronic products and other fields. However, when the battery overcharge, overdischarge, high temperature and other conditions, 18650 cylindrical lithium batteries will also have safety risks.
It should be noted that the use of 18650 lithium batteries must comply with safety norms, the correct use and maintenance of the battery, to avoid excessive charge and discharge, excessive discharge, excessive temperature and other operations, to avoid battery damage, leakage, fire or even explosion and other dangerous situations. When using 18650 lithium batteries, you should choose regular brands and manufacturers, and use special chargers and protection circuits to ensure safety and good performance.
