1. The capacity of the 18650 lithium battery with large capacity is generally between 1200mah and 3600mah, while the general battery capacity is only about 800mah. If combined into a 18650 lithium battery pack, the 18650 lithium battery pack can easily exceed 5000mah.
2. Long service life 18650 lithium battery has a long service life. Its cycle life can reach more than 500 times in normal use, more than twice that of ordinary batteries.
3. High safety performance 18650 lithium battery high safety performance, no explosion, no combustion; Non-toxic, pollution-free, RoHS trademark certification; All kinds of safety performance are completed at one go, and the number of cycles is more than 500; High temperature resistance, discharge efficiency reaches 100% at 65 ℃. In order to prevent battery short circuit, the positive and negative poles of 18650 lithium battery are separated. So the possibility of short circuit has been reduced to the extreme. A protective plate can be installed to avoid overcharge and over-discharge of the battery, which can also extend the service life of the battery.
4. The voltage of 18650 lithium battery is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of NiCd and NiMH battery.
5. Without memory effect, it is not necessary to empty the remaining power before charging, which is convenient to use.
6. Small internal resistance: the internal resistance of polymer cells is smaller than that of ordinary liquid cells. The internal resistance of domestic polymer cells can even be less than 35m Ω, which greatly reduces the self-consumption of batteries, extends the standby time of mobile phones, and can fully meet the international standards. This polymer lithium battery supporting large discharge current is an ideal choice for remote control model, and it is the most promising product to replace Ni-MH battery.
7. 18650 lithium battery pack can be combined in series or parallel
8. Widely used notebook computers, walkie-talkies, portable DVDs, instruments, audio equipment, aircraft models, toys, video cameras, digital cameras and other electronic equipment
shortcoming
The biggest disadvantage of the 18650 lithium battery is that its size has been fixed, and it is not easy to locate when it is installed in some notebooks or some products. Of course, this disadvantage can also be said to be an advantage. This is a disadvantage compared with the customizable and changeable size of other polymer lithium batteries and other lithium batteries. Compared with some products with specified battery specifications, it has become an advantage.
The 18650 lithium battery is prone to short circuit or explosion, which is also relative to the polymer lithium battery. If compared with the ordinary battery, this disadvantage is not so obvious.
The 18650 lithium battery production needs to have a protective circuit to prevent the battery from being overcharged and discharging. Of course, this is necessary for lithium batteries, which is also a common disadvantage of lithium batteries, because the materials used in lithium batteries are basically lithium cobaltate materials, while lithium cobaltate batteries can not discharge with large current, and the safety is poor.
The 18650 lithium battery requires high production conditions. Compared with the general battery production, the 18650 lithium battery requires high production conditions, which undoubtedly increases the production cost.
