What type of batteries are used in mobile power?

Mobile power supply (MPP), also known as rechargeable battery, travel charger, etc., is a portable charger that combines power supply and charging functions in one. It can charge cell phones, tablets and other digital devices anytime and anywhere. Generally use lithium battery (or dry cell, less common) as the power storage unit, easy to use and fast.

Mobile power cells are mainly divided into 18650 cells and polymer cells. The most common on the market is 18650 lithium-ion batteries, with a market share of 70%.

At present, 18650 battery technology is more mature, its battery structure is stable, high specific capacity, outstanding overall performance, small size, wide range of applications. However, its safety is worse than lithium polymer batteries, and the number of cycles of the cell is low, about 300 times.

The main advantages of polymer batteries.

(1) Long service life. Charge and discharge more than 500 times without problems.

(2) Diversified appearance, the use of 18650 battery products are thick and large, the shape of the millennium remains unchanged.

(3) safe to use, mostly used in high-end products. The safety of polymer batteries is reflected in the non-explosion, only bulging, spontaneous combustion and other possible occurrences.

(4) high capacity, in the same package volume (note, package volume), polymer batteries can store more power, so most lighter and thinner, good portability, directly enhance the user's experience.

(5) The disadvantage is the high cost, the same capacity of polymer batteries than 18650 lithium-ion batteries expensive at least 10%.

Conclusion: Consumers will benefit from using safer and higher capacity Li-polymer batteries, but such products are more expensive.
