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

Including Apple's smartphones and tablets, because of the burning and explosion accidents of the built-in lithium battery, people are full of questions about driving mobile power products of the same power. Consumers are worried that mobile power may become another source of such unconfidence, and The 18650 lithium battery technology is one of its weaknesses. As the most mature liquid lithium battery type in the world, the 18650 cylindrical lithium battery is widely used in mobile terminal devices, especially tablet computers and smart phones, whether as a single battery or as a battery pack. However, the structural characteristics of the 18650 battery make it unpreventable. It has been announced that the explosion accident is due to the short circuit of the lithium battery (group) in 18650: if it is used improperly or designed by its own problems, because the battery will make the lithium battery (group) ) The internal pressure is too high. In the case of leaking 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 batteries as energy storage units. This lithium battery has two technical routes. One is a liquid lithium battery. The so-called 18650 lithium battery is based on its 18mm diameter and 65mm height specifications; the other is a polymer lithium battery, which is generally designed as a square lithium battery. The polymer lithium battery is also used as an electric drive for many devices because it can be in any shape. Applying it to mobile power supplies can meet the needs of users for miniaturization and refinement of mobile power supplies. However, the factory cost of polymer lithium batteries is higher because they use different materials than liquid lithium batteries. Many consumers seem to have been pursuing high-capacity and low-cost mobile power supplies, but they did not realize that these requirements are inconsistent with the current state of battery technology. Some of the current mobile power brands, such as feathers, are quality-winning, and products can be used to open market access. Without exception, the early 18650 battery technology will be relatively cheap. As mentioned earlier, the 18650 battery has problems in other applications. Mobile terminals to mobile power cannot be completely prevented. Consumers worry that commercial mobile power is not alarmist. If consumers inadvertently buy inferior mobile power, or overcharge, they can make mobile power work during the process of electrolysis and electrolysis of hydrogen. The release of heat at a normal level cannot be effectively prevented. This is because the internal short circuit of the battery causes explosion and combustion. Therefore, in addition to choosing polymer lithium battery mobile power sources, consumers should also choose products from regular manufacturers. Although the price is slightly higher, the safety is more guaranteed. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
