　　This type of lithium battery cell refers to the rechargeable battery diameter of 18mm, the full length of 65mm,0 indicates cylindrical rechargeable battery. The technology is relatively perfect, the battery structure is stable, the specific capacity is high, the comprehensive performance is prominent, in addition, because of its small size, it can be used in several industries, with key practical significance. The flaw depends on the fact that it is not as safe as polymer lithium batteries, which have a relatively low cycle frequency of about 300 cycles.

　　18650 cell is usually cylindrical type, generally used aluminum shell product packaging design. Crucially, because the 18650's lithium-ion battery behaves mostly as a liquid, like a glass filled with water, the 18650 is only cylindrical.

　　But the risk source of 18650 is still very large, the key is that 18650 product packaging design generally chooses steel cover shell, if the manufacturer can not be manipulated in the process of processing problems resulting in poor product quality, it is very easy to appear explosive difficulties.
