  • The main applications of alumina ceramics in new energy vehicles:


  • Application in batteries


a. Electrolyte material

In the electric vehicle battery, the electrolyte material is one of the key factors that determine the battery performance and safety. #Alumina ceramic electrolyte has high ionic conductivity and high-temperature resistance, which can effectively improve the safety and energy density of the battery. At present, researchers are studying how to improve the micro-structure of alumina ceramic electrolyte and optimize ion channels to further improve its ionic conductivity and stability.


b. Battery separator

The separator is another key component in the electric vehicle battery, whose main function is to separate the positive and negative electrodes to prevent short circuits. Alumina ceramic separators have the advantages of high strength, high toughness, high chemical stability, etc., which can effectively improve the life and safety of batteries. In addition, #alumina ceramic separators can also achieve fast charging, thereby improving the charging efficiency of batteries. Battery negative electrode material is another important component in electric vehicle batteries, which determines the energy density and charge-discharge efficiency of the battery. Alumina ceramic negative electrode materials have high capacity and good cycle performance, which can effectively improve the charge-discharge efficiency and life of batteries. In addition, alumina ceramic negative electrode materials also have good corrosion resistance and high-temperature stability, which can provide a better safety guarantee for batteries.
