What is the principle of polymer lithium ion battery?

There are currently two types of lithium ion batteries: liquid lithium ion batteries (LIB) and polymer lithium ion batteries (PLB). Among them, the liquid lithium ion battery refers to a secondary battery in which Li+ intercalation compounds are positive and negative electrodes. The positive electrode adopts lithium ion compound LiCoO2, LiNiO2 or LiMn2O4, and the negative electrode adopts lithium ion carbon intercalation compound LixC6. The typical battery system is: (-)C|LiPF6EC+DEC|LiCoO2(+) Positive electrode reaction (reduction reaction): Li1-xCoO2 +xLi++xe-u003dLiCoO2-----------(2.1) negative electrode reaction (oxidation reaction): LixC6-xe-u003d6C+xLi+----------- (2.2) The total reaction of the battery: Li1-xCoO2+LixC6u003dLiCoO2+6C-----------(2.3) The principle of polymer lithium ion battery is the same as that of liquid lithium ion. The important difference is The electrolyte is different from liquid lithium ion. The important structure of the battery includes three elements: positive electrode, negative electrode and electrolyte. The so-called polymer lithium ion battery means that at least one or more of these three important structures use polymer materials as an important battery system. In the polymer lithium-ion battery system currently developed, polymer materials are mainly used in the positive electrode and electrolyte. Cathode materials include conductive polymer or inorganic compounds used in general lithium-ion batteries. The electrolyte can use solid or colloidal polymer electrolytes, or organic electrolytes. Generally, lithium technology uses liquid or colloidal electrolytes, so it must be strong. The secondary packaging to contain the flammable active ingredients, which adds weight, and also limits the flexibility of size.
