What are the drawbacks of 18650 lithium batteries.

The biggest drawback of 18650 lithium-ion batteries is that their volume is already fixed, making them difficult to locate when installed in some laptops or products. Of course, this drawback can also be considered an advantage, compared to other polymer lithium-ion batteries and other lithium-ion batteries that can be customized and can be changed in size. This is a disadvantage. And for some products with specified battery specifications, it has become an advantage.

18650 lithium-ion batteries are prone to short circuits or explosions, which is also related to polymer lithium-ion batteries. If compared to ordinary batteries, this disadvantage is not so obvious.

The production of 18650 lithium-ion batteries must have protective circuits to prevent the battery from being overcharged and causing discharge. Of course, this is necessary for lithium-ion batteries, and it is also a common disadvantage of lithium-ion batteries, because the materials used in lithium-ion batteries are mostly lithium cobalt oxide materials, and lithium-ion batteries made of cobalt oxide materials cannot discharge large currents, resulting in poor safety.

The production conditions of 18650 lithium-ion batteries require high requirements, which undoubtedly increases production costs compared to general battery production.

The theoretical lifespan of 18650 batteries is 1000 cycles of charging. Due to the large capacity per unit density, most of the 18650 is used for laptop batteries. In addition, due to its excellent stability performance in work, it is widely used in various electronic fields: commonly used in high-end strong light flashlights, portable power supplies, wireless data transmitters, electric heating and warm clothing, shoes, portable instruments and meters, portable lighting equipment, portable printers, industrial instruments, medical instruments, etc.
