Burning and explosion accidents in smartphones and tablets including Apple products due to built-in lithium batteries have made people full of doubts about mobile power products driven by the same power. Consumers are worried that mobile power supplies may become such unsafe factors. Another source, and 18650 lithium battery technology is one of its weaknesses.
Burning and explosion accidents in smartphones and tablets including Apple products due to built-in lithium batteries have made people full of doubts about mobile power products driven by the same power. Consumers are worried that mobile power supplies may become such unsafe factors. Another source, and 18650 lithium battery technology is one of its weaknesses.
As the most technically mature liquid lithium-ion battery type in the world, 18650 cylindrical lithium batteries are widely used in mobile terminal devices, especially in tablets and smartphones, either in single form or in battery pack form; however, the 18650 battery structure Characteristics make it inevitable that there are certain defects. Judging from the reported explosion accidents of the above-mentioned equipment, they are all caused by short circuit of the 18650 lithium battery (pack): if used improperly or due to problems with the battery cell design itself, The internal pressure of the lithium battery (pack) will be too high. When the pressure leaks out, it will cause pressure on the hard shell (steel shell or aluminum shell) of the battery, causing the shell to explode.
Current mobile power products use lithium batteries as energy storage units. There are two technical routes for this "lithium battery". One is liquid lithium-ion battery cells. Because the 18650 model technology is the most mature, it is also represented by 18650 lithium batteries. . The so-called 18650 lithium battery refers to its specification model with a diameter of 18mm and a height of 65mm; the other is a polymer lithium battery, which is generally designed as a square lithium battery. Because polymer lithium batteries can be shaped into any shape, they are also used as electric drives for many devices. If used in mobile power supplies, consumers' demands for miniaturization and thinness of mobile power supplies can be realized. However, because the materials used in polymer lithium batteries are different from liquid lithium-ion batteries, the factory cost is higher.
Many consumers’ pursuit of high-capacity and low-price mobile power seems to be endless. They don’t quite understand that given the current level of battery technology, the two requirements are contradictory. Several mobile power supply brands that are currently on the front line, such as Yubo, Pinsheng, Pinneng, etc., in order to open up market access, will without exception use the relatively cheap 18650 battery technology in the early stage. As mentioned earlier, 18650 batteries are used in other mobile phones. Problems that occur on terminals cannot be completely avoided when applied to mobile power supplies. Consumers’ concerns about commercially available mobile power supplies are not unfounded. If consumers inadvertently purchase inferior mobile power supplies, or overcharge and overdischarge them, the mobile power supply will be damaged. During the working process, the power source causes the electrolyte to generate hydrogen during electrolysis and releases heat higher than the normal level, which cannot be effectively prevented. This paves the way for an internal short circuit in the battery, which may lead to an explosion or 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.
