Application, advantages and disadvantages of 18650 lithium battery

Application, advantages and disadvantages of 18650 lithium battery

18650 is the ancestor of lithium-ion battery, in which 18 represents a diameter of 18mm, 65 represents a length of 65mm, and 0 represents a cylindrical battery. The common rechargeable 18650 lithium battery has a standard voltage of 3.6 or 3.7v, and 4.2v when fully charged, which has little to do with the power (capacity). The mainstream capacity of the 18650 battery ranges from 1800mAh to 2600mAh.

Application of 18650 lithium battery
The 18650 lithium battery has a large capacity per unit density, so most of it is used as notebook computer batteries. In addition, the 18650 has very good stability in work, and is widely used in various electronic fields: high-end flashlights, portable power supplies, wireless data transmitters, electric thermal clothing, shoes, portable instruments, portable lighting equipment, portable printers, industrial instruments, medical instruments, etc.

Advantages of 18650 Lithium Battery
1. The 18650 lithium battery with large capacity is generally between 1200 mah and 3600 mah, while the general battery capacity is only about 800 mah. If the 18650 lithium battery pack is combined, the 18650 lithium battery pack can easily exceed 5000 mah.

2. Long service life 18650 lithium battery has a long service life. The cycle life in normal use can reach more than 500 times, more than twice that of ordinary batteries.

3. High safety performance 18650 lithium battery has high safety performance. In order to prevent battery short circuit, the positive and negative poles of 18650 lithium battery are separated. Therefore, the possibility of short circuit has been reduced to the extreme. It can also be added with a protective plate to avoid overcharge and overdischarge of the battery, which can also extend the service life of the battery.

4. The voltage of 18650 lithium batteries is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel cadmium and nickel hydrogen batteries.

5. Without memory effect, it is not necessary to empty the remaining power before charging, so it is convenient to use.

6. It can be used in laptop computers, walkie talkies, portable DVDs, instruments, audio equipment, aircraft models, toys, video cameras, digital cameras and other electronic equipment.

Disadvantages of 18650 lithium battery
The biggest disadvantage of the 18650 lithium battery is that its volume has been fixed, and it is not well positioned when it is installed in some products. Of course, this disadvantage can also be said to be an advantage, which is a disadvantage compared with the customizable and changeable size of the polymer lithium battery. However, it has become an advantage over some products with specified battery specifications.

18650 lithium battery requires high production conditions. Compared with ordinary battery production, 18650 lithium battery requires high production conditions, which undoubtedly increases production costs.
