　　What is 18650 lithium battery?

　　The 18650 we talk about in daily life actually refers to the external specifications of the battery, which was a standard model set by Sony Corporation in Japan to save costs. Among them, 18 represents a diameter of 18mm, 65 represents a length of 65mm, and 0 represents a cylindrical battery.

　　18650 battery originally referred to nickel hydrogen battery and lithium-ion battery, but now it mostly refers to lithium-ion battery because nickel hydrogen is less commonly used. Because its positive electrode is a battery made of "lithium cobalt oxide" as the positive electrode material, of course, there are many batteries on the market now, including batteries with lithium iron phosphate, lithium manganese oxide, and other positive electrode materials. The nominal voltage of a single 18650 lithium-ion battery is generally 3.6V or 3.7V; The minimum discharge termination voltage is generally 2.75V. The common capacity is 1200-3100mAh, and a capacity higher than 3400mAh is basically a virtual standard.

　　Scope of use of 18650 lithium battery

　　The 18650 lithium battery can be said to be ubiquitous in daily life, and it has been long-lasting since Sony launched it in the 1990s. 18650 batteries are known for their large capacity and high energy storage efficiency. The advantages of good stability, no memory effect, high cycle life, and no toxic substances are widely used in industrial fields and electronic devices such as laptops, walkie talkies, portable DVDs, instruments and meters, audio equipment, model airplanes, toys, cameras, digital cameras, etc. Even the recently popular Tesla electric vehicle also uses the 18650 battery pack provided by Panasonic.
