　　What are the disadvantages of 18650 lithium-ion battery technology?

　　18650 lithium battery technology has weaknesses, beware of mobile power failures_Smartphones, 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 about mobile power Or will become the other side of this lack of self-confidence

　　Smartphones, tablet computers, including Apple products, because of the burning 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 type of liquid lithium-ion battery in the world, 18650 cylindrical lithium-ion batteries are widely used in mobile terminal equipment, especially tablets and smartphones, whether in the form of a single battery or 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.

　　Current mobile power products use lithium-ion batteries as energy storage units. There are two technical routes for this lithium-ion battery. One is the battery core of the liquid lithium-ion battery. The so-called 18650 lithium-ion battery is based on its diameter of 18mm and height of 65mm; the other is a lithium polymer battery, which is usually designed as a square lithium-ion battery. Lithium polymer 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 use different materials than liquid lithium-ion batteries, so the factory cost is higher.

　　Many consumers seem to be pursuing high-capacity and low-price power banks all the time, but they don't understand that these two requirements are contradictory at the current level 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 lays the foundation for the internal short circuit of the battery leading to explosion and combustion. Therefore, in addition to choosing polymer lithium-ion batteries as mobile power sources, consumers should also choose products produced by regular manufacturers. Although the price is slightly higher, the safety is more guaranteed.
