Obviously, 18650 lithium ion battery has the characteristics of high energy density, large capacity, no memory effect and long service life.
1. The 18650 lithium ion battery has a large capacity. There is no doubt that the capacity of a general 18650 lithium ion battery is between 1200mah and 3600mah, and the capacity can be greatly improved by connecting the battery in series and parallel to the battery pack.
2. 18650 battery has no memory effect, so it is not necessary to empty the remaining power before charging, so it is more convenient to use.
3. Long service life. The service life of 18650 lithium-ion battery is very long. During normal use, the cycle life can reach more than 500 times, which is more than twice that of ordinary batteries.
4. High safety performance, 18650 lithium ion battery has high safety performance, does not explode or pollute the environment. After the data test statement: because the positive and negative electrodes of the 18650 lithium-ion battery are separated, the possibility of short-circuit phenomenon has been reduced to the extreme in most cases. In addition, a protection board can be installed for the 18650 lithium-ion battery. On the one hand, it prevents overcharge and overdischarge of the battery, and can also achieve the effect of extending the service life of the battery.
5. The internal resistance is small and the irreversible capacity loss is small, which greatly reduces the power consumption of the battery itself and prolongs the standby time.
Where are 18650 lithium batteries used?
As the earliest lithium-ion battery, the 18650 lithium-ion battery is also the most mature and stable battery pack in the world, and it is also far ahead of other lithium-ion battery products in terms of market share. The 18650 battery has a wide range of applications. In addition to electric vehicles, electric vehicles and other power industries, it is also used in electronic equipment such as notebook computers, video cameras, and digital cameras.
