How polymer lithium ion batteries work
The principle of a polymer lithium ion battery is the same as that of liquid lithium. The main difference is that the electrolyte is different from liquid lithium. The main 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 the three main structures use a polymer material as a main battery system. In the polymer lithium ion battery system currently developed, polymer materials are mainly used for the positive electrode and the electrolyte.
The positive electrode material includes a conductive high molecular polymer or an inorganic compound used in a general lithium ion battery, and the electrolyte can use a solid or colloidal polymer electrolyte or an organic electrolyte. Generally, a lithium ion technique uses a liquid or a colloidal electrolyte, so it is required The sturdy secondary package accommodates flammable active ingredients, which adds weight and limits size flexibility. The polymer lithium ion process does not have excess electrolyte, so it is more stable, and it is not easy to cause dangerous situations due to overcharging, collision or other damage of the battery, and excessive use.
