Cylindrical lithium batteries can be divided into lithium cobalt oxide batteries, lithium manganese oxide batteries, and ternary batteries. The three material system batteries have different advantages. The batteries are commonly used in: laptop computers, digital SLR cameras, lighting equipment, electric toy products, hardware tools, handheld mobile energy and other fields. What are the types of cylindrical lithium batteries? The types and differences of cylindrical lithium batteries.
The first type of cylindrical lithium battery: 16340 battery
The 16340 battery is a lithium battery with a diameter of 16mm and a height of 34mm. This battery is used in strong light flashlights, LED flashlights, headlights, laser lights, lighting lamps, etc. Often appear.
The second type of cylindrical lithium battery: 18650 battery
The 18650 lithium 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 cost performance. We 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 electrical appliances. superior.
The third type of cylindrical lithium battery: 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 is much higher than 18650 Type batteries are widely used in digital, electric vehicles, balance vehicles, solar energy lithium battery street lights, LED lights, power tools, etc.
The fourth type of cylindrical lithium battery: 10440 battery
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 “No. 7 battery”. The battery capacity is generally small, only a few hundred mAh. It is mainly used in mini electronic products. For example, flashlights, mini speakers, loudspeakers, etc.
The fifth type of cylindrical lithium battery: 14500 battery
The 14500 battery is a lithium battery with a diameter of 14mm and a height of 50mm. This is what we have always called the “No. 5 battery”. This battery is generally 3.7V or 3.2V, with a smaller nominal capacity than 10440 The battery is larger, generally 1600mAh, with superior discharge performance. The main application areas are consumer electronics, such as wireless audio, electric toys, and digital cameras.
Advantages of cylindrical lithium batteries
1. Cylindrical lithium batteries have formed a series of internationally unified standard specifications and models. The technology is relatively mature and suitable for mass continuous production.
2. Cylindrical lithium batteries are generally sealed batteries, and there are no maintenance problems during use.
3. The lithium battery shell has high pressure resistance, and there will be no phenomena such as square, flexible packaging battery expansion during use.
4. The cylinder has a large specific surface area and a good heat dissipation effect.
