What are the advantages and disadvantages of 18650 lithium batteries

1. Long life The 18650 lithium battery has a long service life. The cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. 2. 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-hydrogen 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 service life of the battery. Disadvantages: 1. The biggest disadvantage of 18650 lithium battery is that its volume has been fixed, and it is not well positioned when installed in some notebooks or some products. Of course, this disadvantage can also be said to be an advantage, which is compared with other polymer lithium This is a disadvantage in terms of the customizable and changeable size of lithium batteries such as batteries. And for some products with specified battery specifications, it has become an advantage. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
