What are the cylindrical lithium-ion batteries?

The 10440 battery is a lithium-ion battery with a diameter of 10mm and a height of 44mm. It is the same size as what we often call the AAA battery. The capacity of this battery is generally small, only a few hundred mAh. It is mainly used in mini electronic products. Such as flashlights, mini speakers, loudspeakers, etc. 2. 14500 battery The 14500 battery is a lithium-ion battery with a diameter of 14mm and a height of 50mm. This is also the size we have always called the No. 5 battery. This battery is generally 3.7V or 3.2V, and the nominal capacity is relatively small. , A little larger than the 10440 battery, generally 1600mAh, superior discharge performance, the most important application field is consumer electronics, such as wireless audio, electric toys, digital cameras, etc. 3. 16340 battery 16340 battery is a kind of lithium ion battery with a diameter of 16mm and a height of 34mm. This kind of battery has a shorter foot height and a small capacity, so it is used in strong light flashlights, LED flashlights, headlights, lasers Lamps, lighting fixtures, etc. often appear. 4. 21700 battery The 21700 battery is a lithium-ion battery with a diameter of 21mm and a height of 70mm. Because of its increased volume and space utilization, the energy density of the battery cell and the system can be improved, and its volume energy The density is much higher than that of the 18650 battery, which is widely used in digital, electric cars, balance cars, solar energy lithium-ion battery street lights, LED lights, power tools, etc. Major manufacturers of such batteries include Tesla, Samsung, Panasonic, BAK, and Lion New Energy. 5. 26650 battery 26650 battery is a lithium-ion battery with a diameter of 26mm and a height of 65mm. It has a nominal voltage of 3.2V and a nominal capacity of 3200mAh. This battery has excellent capacity and high consistency, and has gradually become Instead of the 18650 battery trend, many products in power lithium batteries will gradually favor this. 6. The 3265032650 battery is a lithium-ion battery with a diameter of 32mm and a height of 65mm. This battery has a strong continuous discharge capacity, so it is more suitable for electric toys, backup power supplies, UPS batteries, wind power generation systems, and wind and solar hybrid power generation systems.
