18650 Battery
The capacity of the model is as follows: 1. 10440 Battery
The 10440 battery is a lithium battery with a diameter of 10mm and a height of 44 mm. the same as what we often call “7 “Battery” has the same size. This type of battery 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 battery with a diameter of 14mm and a height of 50mm. It's also the size of what we've always called an "AA battery." ". 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 main application areas are consumer electronics, tsuch as wireless speakers. , electric toys, digital cameras, etc.
3. 16340 Battery
The 16340 battery is a lithium battery with a diameter of 16mm and a height of 34mm. This type of battery is shorter in height and its capacity is not very large. small, so they often appear in bright flashlights, LED flashlights, headlights, laser lights, lighting fixtures, etc.
4. 18650 Battery
The 18650 battery is a lithium 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 battery. It has good system quality and good stability in all aspects. suitable for 10 kilowatt hours. Approximate capacityve of the battery, such as in mobile phones, laptops and other small devices.
5. 21700 Battery
The 21700 battery is a lithium battery with a diameter of 21mm and a height of 70mm. Due to its increased volume, the space utilization rate increases and the space utilization rate increases. The battery cell is the energy density of the body and the system can be improved. Its volume energy density is much higher than that of 18650 battery. It is widely used in digital, electric vehicles, balance vehicles, solar lithium 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. It has a nominal voltage of 3.2V and a nominal capacity of 3,200 mAh. This type of battery has characteristics such as excellent capacity and high consistency which have gradually become the trend of replacing 18650 batteries, and many products in electric batteries will gradually promote this.
Cylindrical lithium batteries use a fairly mature winding process with a high degree of automation, stable product quality and relatively low cost. Batteries are widely used in: laptop computers, digital cameras, lighting fixtures, toys, power tools, portable mobile power and other fields.
In addition, the circle cylindrical batteries also have many advantages such as superior cycle performance, fast charging and discharging, high charging efficiency and high output power. I hope to adopt him, thank you
