What is the difference between polymer lithium battery and lithium iron phosphate battery

The main difference between them lies in the difference of electrolyte. Liquid electrolyte is used for liquid lithium-ion battery, while solid polymer electrolyte is used for polymer lithium-ion battery. This polymer can be "dry" or "colloidal". At present, polymer gel electrolyte is mostly used.

According to the different electrolyte materials used in lithium-ion batteries, lithium-ion batteries are divided into liquid lithium-ion batteries (LIB), polymer lithium-ion batteries (PLB) or plastic lithium-ion batteries (PLB). The positive and negative materials used in polymer lithium-ion batteries are the same as those of liquid lithium ions. The positive materials 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 main difference between them lies in the difference of electrolyte. Liquid electrolyte is used for liquid lithium-ion battery, while solid polymer electrolyte is used for polymer lithium-ion battery. This polymer can be "dry" or "colloidal". At present, polymer gel electrolyte is mostly used.

Classification of polymer lithium battery: solid: solid polymer electrolyte lithium ion battery electrolyte is a mixture of polymer and salt. This battery has high ionic conductivity at room temperature and can be used at room temperature.
