What is the model classification of cylindrical lithium-ion batteries?

Cylindrical lithium battery model classification Cylindrical lithium batteries are divided into lithium cobalt oxide, lithium manganate, and ternary materials. The three material system batteries have different advantages. The batteries are widely used in: notebook computers, digital cameras, lighting fixtures, toy products, power tools, portable mobile energy and other fields. There are many types of cylindrical lithium batteries, such as 14650, 17490, 18650, 21700, 26650 and so on. Cylindrical lithium batteries are more popular among lithium battery companies in Japan and South Korea. There are also large-scale companies in my country that process cylindrical lithium batteries. Cylindrical lithium batteries, the important models are 18650, 16650, 14500. 18650 means 18 mm in diameter and 65 mm in length. The AA battery model is 14500, 14 mm in diameter and 50 mm in length. Generally, 18650 batteries are used more in industry and few in civilian use. The common ones are also used in notebook batteries and high-end flashlights. ◆14500 battery The 14500 battery is a lithium battery with a diameter of 14mm and a height of 50mm. This is also the size of the battery that we have always called the No. 5 battery. This battery is generally 3.7V or 3.2V, and the nominal capacity is relatively small. The 10440 battery is larger, generally 1600mAh, with superior discharge performance. The most important application field is consumer electronics, such as wireless audio, electric toys, and digital cameras. ◆16340 battery 16340 battery is a kind of lithium battery with a diameter of 16mm and a height of 34mm. Because the height of the ruler is a little shorter, and the capacity is not very small, it is used in strong light flashlights, LED flashlights, headlights, laser lights, Lighting fixtures and so on often appear. ◆18650 battery The 18650 battery is a lithium battery with a diameter of 18mm and a height of 65mm. Its biggest feature is that it has a very high energy density, almost reaching 170 watt-hours/kg. Therefore, this battery is a battery with better cost performance. Most of the batteries we usually see are this kind of batteries, because they are relatively mature lithium batteries, with good system quality stability in all aspects, and are widely used in applications with battery capacities of about 10 kWh, such as in mobile phones, laptops, etc. On small appliances.
