Important advantages and uses of 18650 lithium ion batteries

The 18650 lithium ion battery has the following advantages. 1. Wide range of use: notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model airplanes, toys, camcorders, digital cameras and other electronic equipment. 2. Series can be combined in series or in parallel to form a 18650 lithium ion battery pack. 3. Small internal resistance. The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. The internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone. , Can reach the level of international standards. This kind of polymer lithium ion battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace nickel-hydrogen batteries. 4. There is no memory effect. It is not necessary to empty the remaining power before charging, which is convenient to use. 5. High voltage 18650 lithium-ion battery voltage is generally 3.6V, 3.8V and 4.2V, much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries. 6. High safety performance 18650 lithium-ion battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, and has passed RoHS trademark certification; all kinds of safety performance are completed in one go, and the number of cycles is greater than 500; high temperature resistance performance, 65 degrees The discharge efficiency reaches 100%. In order to prevent the battery short-circuit phenomenon, the positive and negative electrodes of the 18650 lithium-ion battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protection board can be installed to prevent overcharge and overdischarge of the battery, which can also extend the service life of the battery. 7. Long service life The 18650 lithium ion battery has a long service life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. 8. The capacity of 18650 lithium ion battery with large capacity is generally between 1200mah~3600mah, and the general battery capacity is only about 800. If 18650 lithium ion batteries are combined to form a 18650 lithium ion battery pack, the 18650 lithium ion battery pack is casual It can break through the use of 5000mah. In theory, the 18650 lithium ion battery can be recharged a thousand times. This is its lifespan. Therefore, the battery of the notebook computer we use generally chooses the 18650 lithium ion battery as the battery cell. The advantage of 18650 lithium ion battery is its excellent stability, so it is very stable in work. Nowadays, 18650 lithium ion battery is widely used in various electronic fields. Such as mobile power supplies, medical and industrial equipment, various portable devices, and wireless data transmitters. 18650 lithium-ion batteries are the first choice for most IT industries. Because the IT industry has very high requirements for computer configuration and stability, most of the computers used in the IT industry choose to use 18650 lithium-ion batteries as an energy source.
