18650 lithium-ion battery is one of the most widely used lithium battery models, is also one of the most stable performance battery models, 18650 lithium battery technology structure is mature, and strong stability, metal shell pressure and explosion resistance, in short, 18650 lithium-ion battery advantages, the following I briefly list 8 points on the advantages of 18650 lithium battery for your reference;
1、Wide range of use
Large-scale applications in new energy vehicles, electric motorcycles, bicycle lights, digital products in laptop computers, walkie-talkies, portable DVDs, instruments, audio equipment, models, toys, video cameras, digital cameras and other electronic devices are also quite widely used.
2、Series connection
Can be connected in series or parallel to form 18650 lithium-ion battery pack.
3、Small internal resistance
The internal resistance of polymer cells is smaller than general liquid cells, and the internal resistance of domestic polymer cells can even be less than 35m, which greatly reduces the battery's self-consumption and extends the standby time of cell phones, and can completely reach the level of international standards. This support for large discharge current lithium polymer is the ideal choice for remote control models, becoming the most promising alternative to NiMH batteries.
4、No memory effect
No need to empty the remaining power before charging, easy to use.
5、High voltage
The voltage of 18650 Li-ion battery is generally at 3.6V, 3.8V and 4.2V, much higher than the 1.2V of NiCd and NiMH batteries.
6、High safety performance
18650 lithium-ion battery safety performance, non-explosive, non-combustion; non-toxic, non-polluting, after the RoHS trademark certification; a variety of safety performance in one go, the number of cycles is greater than 500 times; high temperature resistance performance, 65 degrees under the conditions of discharge efficiency of 100%.
7、Long service life
The service life of 18650 lithium-ion battery is very long, the cycle life can reach more than 500 times in normal use, which is more than twice of ordinary battery.
8、Large capacity
18650 lithium-ion battery pack capacity is generally 1200mah ~ 3600mah, while the general battery capacity is only about 800, if the combination of 18650 lithium-ion batteries to become 18650 lithium-ion battery pack, the 18650 lithium-ion battery pack is casually can break through 5000mah.
In short, the actual application, 18650 lithium battery advantages. The above is only a small part of the very limited, what other advantages do you think 18650 lithium battery?
