1、 Meaning of lithium battery 18650

18650 is the ancestor of lithium battery. It was the standard lithium battery model formulated by Sony Corporation of Japan at that time to save costs. We often say 18650 lithium ion battery; In fact, it is a lithium ion battery, named after the size and model of the battery, in which 18 represents the diameter of 18 mm, 65 represents the length of 65 mm, and 0 represents the cylindrical battery. The model of No. 5 battery used more in families is 14500, that is, the diameter is 14mm and the length is 50mm. In short, 18650 actually refers to the size and model of the battery. According to the battery type, the common 18650 batteries are divided into lithium ion batteries and lithium iron phosphate batteries. At present, the former is widely used in the market.

2、 Advantages of 18650 Lithium Ion Battery

What are the advantages of the 18,650 Li ion battery? Obviously, 18650 lithium ion battery has the characteristics of high energy density, large capacity, no memory effect and long service life.

1. There is no doubt that the 18650 lithium ion battery has a large capacity. The capacity of 18650 lithium-ion battery is 1200mAh~3600mAh in general. The capacity can be greatly improved through the battery pack composed of series and parallel batteries.

2. The 18650 battery has no memory effect, so it is more convenient to use without clearing the remaining power after charging.

3. Long service life. 18650 lithium ion battery has a long service life. In normal use, the cycle life can reach more than 500 times, more than twice that of ordinary batteries.

4. High safety performance. The 18650 lithium ion battery has high safety performance and will not explode or pollute the environment. Data detection shows that the possibility of short circuit has been reduced to the limit in most cases due to the separation of positive and negative electrodes of 18650 lithium ion battery. In addition, the 18650 lithium ion battery can be equipped with a protective plate, which can not only prevent the battery from overcharging and discharging, but also extend the service life of the battery. 5. Small internal resistance and irreversible capacity loss greatly reduce battery power consumption and extend standby time.
