What are the specifications and models of cylindrical lithium batteries

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. Such as flashlights, mini speakers, loudspeakers, etc. ②14500 battery The 14500 battery is a lithium battery with a diameter of 14mm and a height of 50mm. This battery is generally 3.7V or 3.2V, and has a relatively small nominal capacity, which is a bit larger than the 10440 battery. Generally, it is 1600mAh. It has superior discharge performance. The most important category is consumer electronics, such as wireless audio, electric toys, and digital cameras. ③16340 battery 16340 battery is a kind of lithium 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, laser lights, and lighting. Lamps, etc. often appear. ④18650 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 Wh/kg. Therefore, this battery is a battery with a better cost performance. Usually this kind of battery is often seen because it is a relatively mature lithium battery with good system quality stability in all aspects. It is widely used in applications with a battery capacity of about 10 kWh, such as in mobile phones, laptops and other small-scale applications. Electrically. ⑤ 21700 battery 21700 battery is a kind of 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 is much higher. 18650 battery, widely used in digital, electric vehicles, balance cars, solar energy lithium battery street lights, LED lights, power tools, etc ⑥26650 battery The 26650 battery is a lithium battery with a diameter of 26mm and a height of 65mm, with a nominal voltage of 3.2V and a nominal capacity of 3200mAh. This battery has excellent capacity and high consistency, and has gradually become a substitute for the 18650 battery. Trend, many products in power lithium-ion batteries will gradually love this.
