　　Disadvantages of 18650 lithium battery

　　The biggest disadvantage of the 18650 lithium battery is that its volume has been fixed, and it is not very easy to position when it is installed in some notebooks or some products. Of course, this disadvantage can also be said to be an advantage. This is compared to other lithium batteries such as polymer lithium batteries. This is a disadvantage in terms of customizable and resizable options. Compared with some products with specified battery specifications, it has become an advantage.

　　The production of 18650 lithium batteries requires a protection circuit to prevent the battery from being overcharged and causing discharge. Of course, this is necessary for lithium batteries. This is also a disadvantage of lithium batteries, because the materials used in lithium batteries are basically lithium cobalt oxide materials, and lithium batteries made of lithium cobalt oxide materials cannot be discharged at high currents, which is safe. poor.

　　The production conditions of 18650 lithium batteries are very demanding. Compared with general battery production, 18650 lithium batteries have high requirements on production conditions, which undoubtedly increases production costs.
