Introduction to the types of cylindrical lithium-ion batteries

The first cylindrical lithium-ion battery: 16340 lithium-ion battery. This 16340 lithium ion battery is a lithium battery with a diameter of 16mm and a height of 34mm. Due to its low foot height and large volume, it often appears in strong light flashlights, LED flashlights, headlights, laser lights, lighting equipment, etc. The second type of cylindrical lithium-ion battery: 18650 lithium-ion battery. The 18650 type lithium ion battery is a lithium battery with a diameter of 18mm and a height of 65mm. Its major feature is that it has a high specific energy, which is close to 170 Wh/kg. Therefore, this type of rechargeable battery is more cost-effective, and most of them are commonly seen. They are all this kind of rechargeable batteries, because they are relatively complete lithium-ion batteries, and the system software quality at all levels is stable. It is generally applicable to places where the battery power is up to 10 kWh, such as mobile phones, notebooks and other small household appliances. The third type of cylindrical lithium-ion battery: 21700 lithium-ion battery. Because the volume of the 21700 lithium-ion battery is enlarged, the space utilization rate is improved, and the specific energy of the single lithium battery cell and the system software can be increased. Therefore, the lithium battery with a diameter of 21mm and a height of 70mm has a much higher volume and specific energy than the 18650 lithium-ion battery. It is used in digital technology, battery car, electric balance car, solar power lithium battery road street lamp, LED lamp, pneumatic tool and other industries. The fourth type of cylindrical lithium-ion battery: 10440 lithium-ion battery. The 10440 rechargeable battery is a lithium-ion battery with a diameter of 10 mm and a height of 44 mm. It is the same as the AAA battery that everyone often says. Its volume is generally small, only a few hundred mAh. The key is for small and medium-sized electronics. equipment. For example, camera flash, small speakers, wireless amplifiers, etc. The fifth type of cylindrical lithium-ion battery: 14,500 lithium-ion battery. The 14500 lithium-ion battery is a lithium-ion battery with a diameter of 14mm and a height of 50mm, which is the specification and model specification of the AA battery commonly referred to. This type of rechargeable battery is generally OR, with a smaller tolerance volume and a little larger than the 10440 rechargeable battery. , Generally 1600mAh, good charging and discharging characteristics, the most important uses are consumer electronics, such as wireless audio, electric toy cars, digital cameras, etc. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
