Analyze the advantages and scope of use of 18650 lithium batteries

18650 is the originator of the lithium battery-a standard lithium battery model set by the Japanese SONY company in order to save costs. Among them, 18 means a diameter of 18mm, 65 means a length of 65mm, and 0 means a cylindrical battery. 1. The capacity of a large-capacity 18650 lithium battery is generally between 1200mah and 3600mah, while the general battery capacity is only about 800mah. If combined into an 18650 lithium battery pack, the 18650 lithium battery pack can easily break through 5000mah. 2. Long life The 18650 lithium battery has a long life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. 3. High safety performance 18650 lithium battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, and has passed RoHS trademark certification; various safety performances can be achieved in one go, and the number of cycles is greater than 500; high temperature resistance performance, under 65 degrees The discharge efficiency reaches 100%. In order to guard against the battery short-circuit phenomenon, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protection board can be installed to guard against overcharge and overdischarge of the battery, which can also extend the battery life. 4. High voltage 18650 lithium 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. 5. There is no memory effect. It is not necessary to empty the remaining power before charging, which is convenient to use. 6. 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. In time, it can fully meet the international standards. This kind of polymer lithium 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-metal hydride batteries. 7. It can be combined in series or parallel to form a 18650 lithium battery pack. 8. Wide range of use: notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model airplanes, toys, camcorders, digital cameras and other electronic equipment.
