Advantages of 18650 Lithium Ion Battery

17 Jul 2020 -
The 18650 Lithium Ion Battery has the following advantages:

   1. Wide range of use
Notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model aircraft, toys, video cameras, digital cameras and other electronic equipment.

   2. Series connection
   can be combined in series or parallel to form 18650 Lithium Ion Battery pack.

   3. Small internal resistance
The internal resistance of the polymer cell is smaller than that of the general liquid cell. The internal resistance of the domestic polymer cell can even be less than 35mΩ, which greatly reduces the self-consumption of the battery and extends the standby time of the mobile phone. International level. This Polymer Lithium Battery that supports large discharge current is an ideal choice for remote control models and has become the most promising alternative to nickel-metal hydride batteries.

  4. 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, far 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, no explosion, no burning; non-toxic, non-polluting, RoHS trademark certification; all kinds of safety performance in one go, cycle number is more than 500 times; good high temperature performance, discharge efficiency reaches 100% at 65 degrees . In order to prevent battery short circuit, the positive and negative electrodes of 18650 lithium battery are separated. Therefore, the possibility of short-circuit phenomenon has been reduced to the extreme. A protection board can be added to avoid overcharging and overdischarging of the battery, which can also extend the service life of the battery.

   7. Long service life
   18650 Lithium Ion Battery has a long service life, and the cycle life can reach more than 500 times under normal use, which is more than twice that of ordinary batteries.
    8. Large capacity

   18650 Lithium Ion Battery capacity is generally between 1200mah ~ 3600mah, and the general battery capacity is only about 800, if 18650 lithium battery is combined to form 18650 lithium battery pack, then 18650 lithium battery pack can easily break 5000mah.
