The shortcoming of 18650 lithium-ion battery technology have?

Source: 2020 - 04 - 02 14:55 hits: time including smartphones, tablets, apple products, because of the burning and explosion accident of the built-in lithium battery makes people to drive the same power of mobile power products are full of doubt, consumers worried about mobile power or will become another source of this kind of insecurity, and 18650 lithium ion battery technology is one of its weaknesses. As the world's most sophisticated liquid lithium ion battery types, 18650 cylindrical lithium-ion batteries have been widely used in mobile devices, especially for tablets and smartphones, both as a single battery as the battery pack. However, 18650 battery structure characteristics make it inevitably has some defects, from has unveiled the explosion, is due to the lithium battery (18650 Group) Short circuit: if use undeserved or design your own problem, because the battery will make lithium ion batteries, Group) Internal pressure is too great, in the case of leakage of pressure, the hard shell of the battery, Steel or aluminum shell) Pressure, causing the shell exploded. At present, mobile power products use lithium battery as the energy storage unit. This kind of 'lithium batteries have two technical routes. Is a kind of liquid lithium ion battery. So-called 18650 lithium batteries is 18 mm in diameter and 65 mm in height according to its specifications; The other is a polymer lithium-ion batteries, general design for the square lithium battery. Polymer lithium battery is also used as a lot of electric equipment, because it can be any shape. Applied to the mobile power supply, can satisfy the user demand for mobile power supply miniaturization, refinement. However, polymer lithium battery factory cost is higher, because they use the material is different from liquid lithium ion battery. Many consumers seem to have been in the pursuit of high capacity and low price of mobile power supply, but they don't realize that these requirements and existing state of battery technology is not consistent. Now some mobile power brands, such as feathers, quality win, the product can in order to open the market access, without exception, in the early 18650 battery technology will adopt a relatively cheap price, as I mentioned earlier, 18650 battery in other application problems in the mobile terminal to the mobile power supply can not completely avoid, consumers worried about commercial mobile power supply is not alarmist, if consumers inadvertently bought inferior mobile power supply, or excessive charging, can make the mobile power supply, when electrolysis electrolytic hydrogen in the process of work, higher than normal levels of heat release, and can not effectively prevent, internal short circuit for the battery lead to explosion and combustion. So consumers in addition to choose polymer lithium battery mobile power supply, also select normal manufacturer of products, our price is a bit high, but security is assured.
