What are the disadvantages of 18650 lithium-ion battery technology? Smartphones and tablet computers including Apple products, because of the combustion and explosion accidents of built-in lithium batteries, people are full of doubts about driving mobile power products with the same power. Consumers are worried that mobile power may become another source of this lack of confidence, and 18650 Lithium-ion battery technology is one of its weaknesses
Smartphones and tablet computers including Apple products, because of the combustion and explosion accidents of built-in lithium-ion batteries, people are full of doubts about driving mobile power products with the same power. Consumers are worried that mobile power may become another source of this lack of confidence. And the 18650 lithium-ion battery technology is one of its weaknesses.

As the most mature liquid lithium-ion battery type in the world, 18650 cylindrical lithium-ion batteries are widely used in mobile terminal equipment, especially tablets and smartphones, either as a single battery or as a battery pack. However, the structural characteristics of the 18650 battery make it inevitable that there are some defects. The explosion accident that has been announced is due to the short circuit of the 18650 lithium-ion battery (group): if it is used improperly or the problem is designed by itself, because the battery will make the lithium-ion battery (Group) The internal pressure is too great, and in the case of leakage pressure, the pressure of the battery's hard shell (steel or aluminum shell) will cause the shell to explode.


Currently, mobile power products use lithium-ion batteries as energy storage units. This lithium-ion battery has two technical routes. One is a liquid lithium-ion battery. The so-called 18650 lithium-ion battery is based on its 18mm diameter and 65mm height specifications; the other is a polymer lithium-ion battery, which is generally designed as a square lithium-ion battery. Polymer lithium-ion batteries are also used to power many devices because they can be of any shape. Applying it to the mobile power supply can meet the user's demand for miniaturization and refinement of the mobile power supply. However, polymer lithium-ion batteries are more expensive to manufacture because they use different materials than liquid lithium-ion batteries.

Many consumers seem to be seeking high-capacity and low-priced power banks, but they don't realize that these requirements are inconsistent with the current state of battery technology. Some current mobile power brands, such as Feather, win in quality, and the products can be used in order to open up market access. Without exception, the early 18650 battery technology will be adopted at a relatively cheap price. As mentioned earlier, 18650 batteries have problems in other applications. In the mobile terminal to the mobile power supply can not be completely prevented, consumers worried about commercial mobile power supply is not alarmist, if consumers inadvertently bought a poor quality mobile power supply, or overcharged, can make the mobile power supply, when working in the process of electrolysis and electrolysis of hydrogen, high The release of heat above the normal level cannot be effectively prevented, which causes explosion and combustion due to the internal short circuit of the battery. Therefore, in addition to choosing polymer lithium-ion battery mobile power as much as possible, consumers should also choose products from regular manufacturers. Although the price is slightly higher, the safety is more guaranteed.
