Lithium-Polymer battery classification and safe use Views [0] Published: 2018-01-31 11:54:23


Lithium ion batteries are classified into LiLithium-IonBattery (LIB) and PolymerLithium-IonBattery (PLB for short) according to the electrolyte material used in the lithium-ion battery. Polymer lithium-ion battery used in the positive and negative materials and liquid lithium-ion are the same, the cathode material is divided into lithium cobalt oxide, lithium manganese oxide, ternary materials and lithium iron phosphate material, the negative graphite, the battery basic principle Consistent. Their main difference lies in the different electrolytes, liquid lithium-ion batteries use liquid electrolytes, and polymer lithium-ion batteries use solid polymer electrolytes instead. Such polymers can be "dry" or "colloidal" Most of the current use of polymer gel electrolyte.


Polymer lithium-ion battery has the following characteristics:

① plasticity flexibility;

② higher quality than the energy (3 times the MH-Ni battery);

③ Electrochemical stability window wide, up to 5V;

④ perfect safety and reliability

⑤ longer cycle life, less capacity loss;

⑥ high volume utilization;

⑦ a wide range of applications.
