The types of cylindrical lithium-ion battery with distinction

by:dcfpower     2020-11-17

cylindrical lithium-ion batteries can be divided into the cobalt acid lithium battery, battery manganese acid lithium battery, three yuan. Three kinds of material system the different advantages of the battery, battery widely used in: laptops, digital SLR camera, lighting, electric toys, hardware tools, hand-held move energy, etc. What that breed of cylindrical lithium-ion battery, cylindrical li-ion battery types and differences.

cylindrical lithium battery pack first: 16340 battery

16340 battery is a 16 mm diameter, height is 34 mm of lithium battery, the battery because of feet high, and the capacity is not small, so the strong light flashlight, LED flashlight, head light, laser, lighting lamps and lanterns, often appear.

cylindrical lithium-ion batteries, the second: 18650 battery

18650 lithium battery is an 18 mm diameter, height is 65 mm of lithium battery, its biggest characteristic is to have a very high energy density, reached almost 170 watts/kg, so the battery is good cost performance, we often see the most at ordinary times is the battery, because it is relatively mature lithium-ion batteries, all aspects of system quality stability is better, widely used in about 10 KWH battery capacity situations, for example, in mobile phones, laptops and other small appliances.

cylindrical lithium battery pack and the third: 21700 battery

21700 battery is a 21 mm diameter, height is 70 mm of lithium battery, because of its size, space utilization, energy density batteries monomer as well as the system can be improved, the volume of its energy density is much higher than 18650 type batteries, widely used in digital, electric cars, balance, solar car to lithium battery lights, LED lights, electric tools, etc.

cylindrical lithium-ion batteries a fourth: 16340 battery

16340 battery is a 16 mm diameter, height is 34 mm of lithium battery, the battery because of feet high, and the capacity is not small, so the strong light flashlight, LED flashlight, head light, laser, lighting lamps and lanterns, often appear.

cylindrical lithium-ion battery 5 kinds: 18650 battery

18650 battery is an 18 mm diameter, height is 65 mm of lithium battery pack, its biggest characteristic is to have a very high energy density, reached almost 170 watts/kg, so the battery is good cost performance, we often see the most at ordinary times is the battery, because it is relatively mature lithium-ion batteries, all aspects of system quality stability is better, widely used in about 10 KWH battery capacity situations, for example, in mobile phones, laptops and other small appliances.

cylindrical lithium battery pack 6 kinds: 21700 battery

21700 battery is a 21 mm diameter, height is 70 mm of lithium battery pack, because of its size, space utilization, energy density batteries monomer as well as the system can be improved, the volume of its energy density is much higher than 18650 type batteries, widely used in digital, electric cars, balance, solar car to lithium battery lights, LED lights, electric tools, etc.

cylindrical lithium-ion battery 7 kinds: 10440 battery

10440 battery is a 10 mm diameter, height is 44 mm of lithium battery pack, and we often called & other; 7 battery & throughout; Size, the battery capacity is very small, generally only a few hundred mAh, mainly used in miniature electronic products. Such as a flashlight, mini audio, amplifiers, etc.

cylindrical lithium-ion battery 8 kinds: 14500 battery

14500 battery is a diameter of 14 mm, 50 mm in height of lithium battery, which we have been called & other; 5 battery & throughout; The specifications of the size, the battery is usually 3. 7 v or 3. 2 v, nominal capacity is small, a little larger than 10440 batteries, generally is 1600 mah, discharge performance is superior, the main application field is consumer electronics, such as wireless audio, electric toys, digital camera, etc.

the advantages of cylindrical lithium-ion battery

1. Cylindrical lithium-ion batteries have formed a series of international unified standard and model, technology is mature, suitable for large quantities of continuous production.

2。 As the sealed battery, cylindrical li-ion battery usually use does not exist in the process of maintenance problems.

3。 casing pressure is high, in use process won't appear such as square, flexible packaging cells swell.

4。 Specific surface area of the cylinder, the cooling effect is good.
