锂锰电池

Lithium-manganese cylindrical battery specifications and sizes are usually expressed in five digits, starting from the left, one and two digits refers to the diameter of the battery, the third and fourth digits refer to the battery height, the fifth digit indicates the circle. There are many types of li-mn cylindrical battery, the more common are 10400,14500,16340,18650,21700,26650,32650, etc. .


110440 the 10440 is a lithium-ion battery with a diameter of 10 mm and a height of 44 mm. It is the size of what is commonly called a“Number 7” battery, and it is usually very small, with a capacity of only a few hundred mAh, mainly used in mini-electronics products. Such as flashlights, mini speakers, loudspeakers and so on.


214,500 batteries 14,500 batteries are lithium-ion batteries with a diameter of 14 mm and a height of 50 mm. These batteries are usually 3.7 V or 3.2 v. the nominal capacity is relatively small, a little larger than the 10,440 batteries, and is generally 1600 mah. The discharge performance of these batteries is excellent, the main application areas are consumer electronics, such as wireless audio, electric toys, digital cameras and so on.


316340 Battery 16340 is a lithium-ion battery with a diameter of 16mm and a height of 34mm, therefore in the strong light flashlight, LED flashlight, headlamp, laser light, lighting lamps and so on often appear.


418650 Battery 18650 is a lithium-ion battery with a diameter of 18 mm and a height of 65 mm. It is characterized by a very high energy density of almost 170 watt-hours per kilogram, therefore, this kind of battery is a battery with good performance and price. Most of the batteries that we usually see are this kind of battery, because it is a relatively mature lithium-ion battery, and the quality and stability of all aspects of the system are good, widely used in 10 kilowatt-hour battery capacity occasions, such as, in mobile phones, laptops and other small electrical appliances.


521700 Battery 21700 is a lithium-ion battery with a diameter of 21 mm and a height of 70 mm. As it increases in size and space utilization, the cell monomer and energy density of the system can be increased, its volume energy density is much higher than the 18650 model battery, widely used in digital, electric vehicles, balanced vehicles, solar lithium battery street lamps, LED lights, electric tools.


626650 Battery 26650 is a lithium battery with a diameter of 26mm and a height of 65mm. The nominal voltage is 3.2 V and the nominal capacity is 3200mAh, has gradually become a replacement for the 18650 battery trend, in power batteries in many products will also gradually favor this.


732650 Battery 32650 is a lithium battery with a diameter of 32mm and a height of 65mm, so it is suitable for electric toys, back-up power supply, UPS Batteries, wind power generation system, wind-solar complementary power generation system.
