Lithium polymer cylindrical battery is a type of battery with high energy density and high flexibility, which is widely used in mobile devices, power tools, medical equipment and other fields. Its unique design and excellent performance make it one of the key components of modern technology.

In terms of materials used, the positive electrode materials of polymer lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. The important difference between the positive electrode materials of polymer lithium ion batteries lies in the difference of electrolytes. Liquid lithium ion batteries use liquid electrolytes, and polymer lithium ion batteries use solid polymer electrolytes instead. This polymer can be dry or glued. At present, most of the polymer gel electrolytes are used.

The electrolyte is a conductive ionic conductor between the positive pole and the positive pole of the battery. It is composed of electrolyte lithium salt, high-purity organic solvent, necessary additives and other raw materials in a certain proportion. It plays an important role in the energy density, power density, extensive temperature applications, cycle life and safety performance of batteries.

In the secondary battery industry, lithium polymer batteries have occupied most of the market. At the same time, there are many modular batteries and battery packs in series and parallel. What are the differences between series and parallel batteries? Today, the editor will introduce it to you.

It is believed that many people in the battery market can hear the term 18650 battery, but few friends have seen the battery labeled 18650 battery in the market. At this time, some friends will have questions: What is the 18650 battery? Today, this article will solve this problem, and also answer the difference between 18650 battery and flexible lithium battery?
