Analyze the advantages and parameters of 18650 lithium-ion battery

The parameters and operating temperature range of the 18650 lithium-ion battery are analyzed. A very important invention in history. The battery really solves many problems, greatly improves the efficiency of various lives, and the emergence of lithium-ion batteries makes people understand that power is getting deeper and deeper. 18650 lithium-ion batteries are It has been used for the longest time, and there is still a kind of lithium-ion battery. The shadow of 18650 lithium-ion battery can be seen in many places. A friend asked the author, what are the parameters of the 18650 lithium ion battery? Please see the 18650 lithium ion battery parameters and operating temperature range explained by the author below. 18650 lithium-ion battery. The advantage of JPG18650 lithium ion battery When the no-load voltage is lower than 3.0V, it is generally considered that the lithium ion battery has no electricity. Most lithium-ion batteries cannot be discharged under a no-load voltage below 3.2v, otherwise excessive discharge will damage the battery. 4.2V is the highest limit of battery voltage. It is generally believed that the no-load voltage 4.2V for lithium-ion battery charging is electricity. During the battery charging process, the battery voltage gradually rises from 3.7V to 4.2V, and lithium-ion batteries cannot exceed 4.2V with no-load voltage. V, otherwise it will damage the battery. This is a special place for lithium-ion batteries. Generally speaking, 18650 lithium-ion batteries have the following advantages. 1. Wide range of uses. Notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, airplane models, toys, camcorders, digital cameras and other electronic equipment. 2. Series. 18650 lithium-ion batteries can be combined in series or in parallel. 3. The internal resistance of small polymer batteries is less than that of liquid batteries. The internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces battery power consumption and prolongs the standby time of mobile phones, which can reach international standards. The polymer lithium-ion battery supports large discharge currents and is ideal for remote control models, and is the most promising alternative to nickel metal hydride batteries. 4. There is no memory effect. There is no need to empty the remaining power before charging, which is convenient to use. 5. High voltage. The voltage of 18650 lithium ion battery is generally 3.6v, 3.8v, 4.2v, which is much higher than the 1.2v voltage of nickel-cadmium battery and nickel-hydrogen battery. 6. High safety performance. 18650 lithium ion battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, RoHS trademark certification; various safety performance, more than 500 cycles; high temperature resistance, 65 degrees power efficiency as high as 100%. In order to prevent short circuits, the positive and negative electrodes of the 18650 lithium-ion battery are separated. Therefore, the possibility of its short circuit has been reduced to the limit. You can add a protective panel to prevent the battery from being overcharged, which can extend the life of the battery. 7. Long service life. The 18650 lithium-ion battery has a long service life. The cycle life in normal use is more than 500 times that of ordinary batteries and more than twice that of ordinary batteries. 8. Large capacity. The capacity of 18650 lithium ion battery is generally between 1200mah~3600mah, and the general battery capacity is only about 800. If the 18650 lithium ion battery is combined with the 18650 lithium ion battery pack, the 18650 lithium ion battery pack can easily exceed 5000mah.
