Cylindrical batteries are divided into lithium cobalt oxide, lithium manganate and ternary materials. Batteries in the three-material system have different advantages. Let's take a look at the models and specifications of cylindrical batteries.
Cylindrical lithium-ion batteries are usually represented by five numbers starting from the left, the first and second numbers refer to the diameter of the battery, the third and fourth numbers refer to the height of the battery battery and the fifth digit. refers to the height of the battery. The numbers represent circles. There are many models of cylindrical batteries, among which the most common are 10400, 14500, 16340, 18650, 21700, 26650, 32650, etc.
1. 10440 Battery
The 10440 battery is a lithium-ion battery with a diameter of 10 mm and a height of 44 mm. It is the same size as what is often calledone AA battery. This battery The capacity is generally very small, only a few hundred mAh, and is mainly used in mini electronic products. Such as flashlights, mini speakers, amplifiers, etc.
2. 14500 Battery
The 14500 battery is a lithium-ion battery with a diameter of 14 mm and a height of 50 mm. It's also the size of what we've always called AA. Batteries. This type of battery is generally 3.7V or 3.2V. The rated capacity is relatively small, a little larger than the 10440 battery, generally 1600mAh, and has excellent discharge performance. The most important areas of application are consumer electronics. wireless speakers, electric toys, digital cameras, etc.
3. 16340 Battery
The 16340 battery is a lithium-ion battery with a diameter of 16mm and a height of 34mm. This battery is shorter in heightr and its capacity is not very large. small, so it often appears in bright flashlights, LED flashlights, headlights, laser lights, lighting fixtures, etc.
4. 18650 Battery
The 18650 battery is a lithium-ion battery with a diameter of 18mm and a height of 65mm. Its greatest characteristic is that it has a very high energy density. , almost 170 watts/hour/kg, this type of battery is therefore a cost-effective battery. Most of us see this type of battery often because it is a relatively mature lithium-ion battery. It has good system quality and good stability in all aspects. and is widely used in 10 cases where the battery capacity is about kilowatt hours, for example in mobile phones, laptops and other small household appliances.
5. 21700 Battery
The 21700 battery is a lithium-ion battery with a diameter of 21 mm and a hauthor of 70 mm. Due to its increased volume, the space utilization rate becomes greater. The energy density of the single unit and the system can be improved. Its volumetric energy density is much higher than that of 18650 battery. It is widely used in digital vehicles, balance cars, lithium-ion battery solar street lights. LED lights, power tools, etc. The main manufacturers producing this type of batteries are Tesla, Samsung, Panasonic, BAK, Mengshi New Energy, etc.
6. 26650 Battery
The 26650 battery is a lithium battery with a diameter of 26mm and a height of 65mm. Ion battery, rated voltage 3.2V, rated capacity 3200mAh. This type of battery has excellent capacity and high consistency. It has gradually become a trend to replace 18650 batteries. Many products in power lithium batteries will also favor it.nt.
