18650 battery is a lithium-ion battery with a diameter of 18mm and a height of 65mm. Its biggest characteristic is that it has a very high energy density, almost reaching 170 watt hours/kilogram. Therefore, this type of battery is a cost-effective battery. We often see this type of battery because it is a relatively mature lithium-ion battery, with good system quality stability in all aspects, and is widely used in battery capacity scenarios of around 10 kilowatt hours, For example, on small appliances such as mobile phones and laptops.

Cylindrical lithium-ion battery type 6: 21700 battery

21700 battery is a lithium-ion battery with a diameter of 21mm and a height of 70mm. As its volume increases, space utilization efficiency increases, and the energy density of battery cells and systems can be improved. Its volume energy density is much higher than that of the 18650 battery, and it is widely used in digital, electric vehicles, balance vehicles, solar lithium-ion battery street lights, LED lights, electric tools, etc.

Cylindrical lithium-ion battery type 7: 10440 battery

The 10440 battery is a lithium-ion battery with a diameter of 10mm and a height of 44mm. It is the same size as the commonly referred to as the No. 7 battery, and its capacity is generally very small, only a few hundred mAh. It is important for applications in mini electronic products. For example, flashlights, mini speakers, amplifiers, etc.

Cylindrical lithium-ion battery type 8: 14500 battery

The 14500 battery is a lithium-ion battery with a diameter of 14mm and a height of 50mm, which has always been referred to as the size of the 5th battery. This type of battery is generally 3.7V or 3.2V, with a nominal capacity of slightly smaller than the 10440 battery, usually 1600mAh. It has excellent discharge performance and is most important in consumer electronics applications, such as wireless audio, electric toys, digital cameras, etc.
