Introduction to polymer lithium ion batteries and application areas

Polymer lithium ion battery is also called lithium polymer battery, also called polymer lithium ion battery. It is also a kind of lithium-ion battery, but compared with liquid lithium-ion battery, it has many obvious advantages such as high energy density, smaller size, ultra-thin, lighter weight, and high safety. It is a new type of battery. In terms of shape, lithium polymer batteries have ultra-thin characteristics, and can be made into batteries of any shape and capacity according to the requirements of various products. The minimum thickness that this type of battery can reach can reach 0.5mm. Its nominal voltage is the same as that of Li-ion and it is also nominal voltage 3.7V, without memory effect. Polymer lithium-ion batteries generally have the characteristics of good discharge characteristics, strong plasticity, high safety, high cell voltage, light weight, large capacity, low internal resistance, long life, no memory effect, and simple protection board design. The positive and negative materials used in the lithium polymer battery polymer lithium ion battery are the same as the liquid lithium ion. The positive electrode material is divided into lithium cobalt oxide, lithium manganate, ternary material and lithium iron phosphate material. The negative electrode is graphite, and the battery The working principle is basically the same. Their important difference lies in the difference in electrolytes. Liquid lithium-ion batteries use liquid electrolytes, while polymer lithium-ion batteries are replaced by solid polymer electrolytes. This polymer can be dry or colloidal. Part of the use of polymer gel electrolyte. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
