The advantages and disadvantages of 18650 lithium ion power battery and its application are briefly described.

The 18,650 lithium-ion battery is one of the earliest lithium-ion battery lithium-ion battery. Battery recycling line The 18650 is actually the size of a battery. The typical 18,650 batteries are also divided into lithium-ion battery and lithium iron phosphate battery. Eighteen lithium-ion battery are 18 millimeters in diameter, 65 are 65 millimeters in length, and zero are cylindrical cells.

Advantages of 18650 lithium ion battery

Large capacity: The 18650 Mach lithium-ion battery is usually between Mach 1200 and 3600, lithium battery welding machine while the typical battery capacity is only about Mach 800, and the capacity of the 18650 lithium-ion battery can easily exceed Mach 5000.

long life: 18650 lithium-ion battery has a long service life, and the cycle life can reach more than 500 times during normal use, which is more than twice that of ordinary batteries.

High Safety Performance: the 18650 lithium-ion battery has high safety performance. mounting machine To prevent short circuit failure of the battery system, the positive and negative poles of the 18650 lithium-ion battery are separated. So its short-circuit probability is as low as we can get. By installing the Protection Board, the overcharge and overdischarge of the battery can be avoided and the network life of the battery can also be extended by students.

High voltage: The voltage of 18650 lithium-ion battery is generally 3.6V, 3.8V and 1.2V, which is much higher than that of Ni-Cd and Ni-MH batteries.

no memory effect, no need to empty the remaining power before charging, easy to use.

Low internal resistance: The internal resistance of polymer battery is smaller than that of ordinary liquid battery. The internal resistance of domestic polymer battery can be lower than 35 Ω, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone, and can reach the international standard. Li-polymer, which supports large discharge current, is an ideal choice for remote control model and the most promising substitute for Ni-MH battery.

The 18650 lithium-ion battery pack can be connected in series or combined.

Notebooks or computers, walkie-talkies, portable DVDs, instruments and meters, sound system equipment, model airplanes, toys, cameras, digital cameras and other electronic technology equipment are widely used.
