Classification and application of polymer lithium ion batteries

Polymer lithium ion battery is abbreviated as polymer lithium battery, which corresponds to liquid lithium ion battery. The fundamental feature of polymer lithium battery is that at least one of the three elements of positive electrode, negative electrode or electrolyte uses polymer materials. Practical polymer lithium batteries use polymer materials in the positive electrode or electrolyte. The polymer lithium battery got its name from the non-liquid structure of its electrolyte. Until now, the polymer lithium battery can be divided into three types. 1. Solid electrolyte polymer lithium battery: the electrolyte is a solid mixture of polymer and salt, suitable for high temperature use; 2. Gel-like electrolyte polymer lithium battery: a plasticizer is added to the solid polymer electrolyte to improve the ion Conductivity; 3. Positive polymer lithium battery: It uses conductive polymer as the positive electrode material to greatly increase the energy of polymer lithium battery. Polymer lithium battery is currently the most superior lithium battery, and it can even be said to be the most excellent battery. The unit energy of polymer lithium battery is 50% higher than that of liquid lithium ion battery, and its capacity and life are greatly improved. Its advantages in safety, adaptability to working conditions and environmental performance make it a new generation of lithium ion Battery. Polymer lithium batteries are mainly used in portable products, such as notebook computers, mobile power supplies, etc. At present, polymer lithium batteries have appeared in the design of thinner, arbitrary area and arbitrary shape directions. These advantages are the market for polymer lithium batteries. Growth provides a lot of flexibility.
