18650 lithium-ion battery technology has weaknesses, beware of mobile power failure_

Smartphones and tablets, including Apple products, are full of doubts about the burning and explosion accidents of built-in lithium-ion batteries that make people drive power bank products with the same power. Consumers are worried that power banks may become another source of this lack of confidence. , and the 18650's 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 devices, especially tablets and smartphones, whether in single battery form or battery pack form. However, the structural characteristics of the 18650 battery make it inevitable that there are some defects. Explosion accidents have been reported due to short circuits in the 18650 lithium-ion battery (Group): if it is used improperly or has its own design problems, the battery will cause the lithium-ion battery to (Group) The internal pressure is too great. In the event of pressure leakage, the pressure on the hard shell (steel or aluminum shell) of the battery will cause the shell to explode.

Current power bank products use lithium-ion batteries as energy storage units. There are two technical routes for this lithium-ion battery. One is the battery cell of liquid lithium-ion battery. The so-called 18650 lithium-ion battery is a model with a diameter of 18mm and a height of 65mm; the other is a lithium polymer battery, usually designed as a square lithium-ion battery. Lithium polymer batteries are also used to power many devices because they can be made in any shape. Applying it to mobile power supplies can meet users' needs for miniaturization and refinement of mobile power supplies. However, polymer lithium-ion batteries use different materials than liquid lithium-ion batteries, so the factory cost is higher.

Many consumers seem to have been pursuing high-capacity and low-price mobile power supplies, but they do not understand that under the current level of battery technology, these two requirements are contradictory. Some current mobile power brands, such as Feather, win by quality, and their products can open market access. Without exception, the early 18650 battery technology will be adopted at relatively cheap prices. As mentioned earlier, 18650 batteries have problems in other applications. In mobile terminals, mobile power supplies cannot be completely prevented. Consumers' worries about commercial mobile power supplies are not alarmist. If consumers accidentally buy inferior mobile power supplies or overcharge them, the mobile power supply, when working in the process of electrolyzing electrolytic hydrogen, can become highly charged. The normal level of heat release cannot be effectively prevented, which lays the foundation for the internal short circuit of the battery to cause 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.
