Cylindrical lithium battery model specification analysis

The 10440 battery is a lithium 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, which is mainly used in mini electronic products. For example, flashlights, mini speakers, loudspeakers, etc. 2. 14500 battery The 14500 battery is a lithium 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, with a relatively small nominal capacity. A bit larger than the 10440 battery, usually 1600mAh, with superior discharge performance. The most important use category is consumer electronics, such as wireless audio, electric toys, and digital cameras. 3. 16340 battery 16340 battery is a kind of lithium battery with a diameter of 16mm and a height of 34mm. Because the height of this battery is a little shorter, and the capacity is not very small, it is used in strong light flashlights, LED flashlights, headlights, and laser lights. , Lighting fixtures, etc. often appear. 4. 18650 battery The 18650 battery is a lithium battery with a diameter of 18mm and a height of 65mm. Its biggest feature is that it has a very high energy density, almost reaching 170 watt-hours/kg. Therefore, this battery is a battery with a better price-performance ratio. , We usually see this type of battery, because it is a relatively mature lithium battery, and the system quality is stable in all aspects. It is widely used in applications with a battery capacity of about 10 kWh, such as in mobile phones and laptops. And so on small appliances. 5. 21700 battery The 21700 battery is a lithium 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 volumetric energy density Much higher than the 18650 battery, it is widely used in digital, electric vehicles, balance vehicles, solar energy lithium battery street lights, LED lights, power tools, etc. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
