With the development of lithium battery technology, there are more and more types of cylindrical lithium batteries. Cylindrical lithium ion batteries are divided into lithium cobalate, lithium manganate and ternary materials. The three material systems have different advantages. Now let's take a look at the models and specifications of cylindrical lithium batteries.
Cylindrical lithium ion battery cells are usually represented by five digits. From the left, the first and second digits refer to the diameter of the battery, the third and fourth digits refer to the height of the battery, and the fifth digit refers to the circle. There are many types of cylindrical lithium batteries, including 10400, 14500, 16340, 18650, 21700, 26650, 32650, etc.
1. 10440 Battery
10440 battery is a kind of lithium-ion battery with a diameter of 10mm and a height of 44mm. It is the same size as what we often call No. 7 battery. The capacity of this battery is generally very small, only a few hundred mAh. It is important to use in mini electronic products. Such as flashlight, mini stereo, loudspeaker, etc.
2. 14500 battery
14500 battery is a kind of lithium-ion battery with a diameter of 14 mm and a height of 50 mm, which is also what we have always called the size of No. 5 battery. This battery is generally 3.7V or 3.2V, with a smaller nominal capacity, a little larger than 10440 battery, generally 1600mAh, and excellent discharge performance. The most important application fields are consumer electronics, such as wireless audio, electric toys, digital cameras, etc.
3. 16340 Battery
16,340 battery is a kind of lithium-ion battery with a diameter of 16mm and a height of 34mm. Due to its low height and small capacity, it often appears in strong flashlights, LED flashlights, headlights, laser lamps, lighting fixtures, etc.
4. 18650 Battery
18650 battery is a kind of lithium-ion battery with a diameter of 18mm and a height of 65mm. Its biggest feature is that it has a very high energy density, almost 170 watt hours/kg. Therefore, it is a battery with good cost performance ratio. Most of the batteries we usually see are this kind of battery, because it is a relatively mature lithium-ion battery. The system quality stability is good in all aspects, and it is widely used in situations with a battery capacity of about 10 kilowatt hours, For example, on mobile phones, laptops and other small appliances.
