18650 lithium-ion battery

　　The characteristics of polymer 18650 lithium-ion battery are as follows:

　　One is the flexibility of shaping; the second is the higher quality energy density (3 times MH-Ni rechargeable battery); the third is the photocatalytic stability window is as wide as 9V; the fourth is completely reliable safety factor; the fifth is the long life of the circulation system , low consumption; high volume utilization rate;

　　Principle of polymer lithium-ion battery.

　　At this stage, ion batteries are divided into two categories: liquid lithium batteries (LIB) and polymer lithium ion batteries (PLB). Among them, liquid lithium batteries refer to positive and negative secondary batteries containing Li+ implanted chemicals. The positive component is LiCoO2, LiNiO2 or LiMn2O4, the negative component is LixC6, and the positive component is LixC6. The typical rechargeable battery system is:

　　C|LiPF6EC+DEC|LiCoO2(+)

　　Positive electrode reaction (reduction reaction): Li1-xCoO2+xLi++xe-=LiCoO2-----------(2.1)

　　Negative reaction (redox reaction): LixC6-xe-=6C+xLi+-----------(2.2)

　　The overall reflection of the lithium battery pack: Li1-xCoO2+LixC6=Li-CoO2+6C-----------(2.3)

　　The principle of polymer 18650 lithium-ion battery is the same as that of liquid lithium batteries. The main difference lies in the different electrolytes of lithium batteries. The main structure of the battery consists of three elements: positive stage, negative stage and electrolyte solution. "Polymer lithium battery" refers to a battery system in which at least one or more of these three main structures use polymer as the main structure. And in the currently developed polymer lithium battery system, the use of polymer materials in the positive stage and lithium battery electrolyte is very important. The metal electrode contains conductive polymers or inorganic substances in ordinary lithium batteries. The electrolyte solution can be a solid or colloidal polymer electrolyte solution, or an organic lithium battery electrolyte. Generally, lithium-ion battery technology uses liquid Or colloidal lithium battery electrolyte, so it needs strong secondary packaging to contain flammable specific components, which not only increases the weight, but also limits the compatibility of specifications.

　　The new polymer lithium battery (ATL battery is as thin as mm, equivalent to the thickness of a credit card), free area and free shape, greatly improves the coordination ability of battery product styling, thus meeting product requirements , enabling all types of batteries to have larger capacities and providing equipment developers with some design coordination capabilities and power supply solutions to maximize their product performance. In addition, the kinetic energy of polymer lithium battery companies is more than 20% higher than that of current ordinary lithium batteries, and their capacity and environmental performance are also gradually improved compared to ordinary lithium batteries.
