The application of alumina ceramic in the new energy vehicle sector holds significant importance and broad prospects. Its excellent performance and unique advantages, such as high-temperature oxidation resistance and low density, enable alumina ceramic—including high purity alumina ceramic, alumina ceramic component, and custom alumina ceramic part—to play an increasingly important role in the manufacturing of new energy vehicles.
The Importance of Alumina Ceramics in New Energy Vehicles
With the increasing awareness of environmental protection and the rapid development of new energy vehicle technology, the application of ceramic materials has become increasingly important in the automotive industry. Alumina ceramics, as a high-performance ceramic material,including alumina ceramic substrate and alumina ceramic insulator, plays a crucial role in the field of new energy vehicles.
01 Application in Batteries
Electrolyte Materials
In electric vehicle batteries, electrolyte materials are one of the key factors determining the performance and safety of the battery. Alumina ceramic electrolytes, paired with alumina ceramic separator sheet, have high ionic conductivity and high temperature resistance, which can effectively enhance the safety and energy density of the battery. Currently, researchers are studying how to improve the microstructure of alumina ceramic electrolytes and optimize the ionic channels to further enhance their ionic conductivity and stability.
Battery separator
The separator is another crucial component in electric vehicle batteries. Its main function is to separate the positive and negative electrodes and prevent short circuits. The alumina ceramic separator a core alumina ceramic battery part, has advantages such as high strength, high toughness, and high chemical stability, which can effectively enhance the lifespan and safety of the battery. Moreover, the alumina ceramic separator can also enable rapid charging, thereby improving the charging efficiency of the battery.
Battery anode material
The anode material is another important component in electric vehicle batteries, determining the energy density and charging/discharging efficiency of the battery. The anode material made of alumina ceramics, coated with alumina ceramic coating for enhanced performance, has high capacity and excellent cycling performance, which can effectively improve the charging/discharging efficiency and lifespan of the battery. Moreover, the anode material made of alumina ceramics also has good corrosion resistance and high-temperature stability, providing better safety guarantees for the battery.
02 Other Applications
Automobile Brake Discs
Alumina ceramic brake discs, a key alumina ceramic automotive component, possess characteristics such as high strength, high wear resistance, and high corrosion resistance, which can effectively enhance the stability and safety of braking. Additionally, alumina ceramic brake discs have good thermal stability and can withstand high-temperature friction, reducing braking friction losses and improving the reliability and lifespan of braking.
Automobile Sensors
Alumina ceramic sensors, built with alumina ceramic base for stable support, have features such as high sensitivity, high stability, and high corrosion resistance, and can be widely applied in various sensors of automobiles, such as temperature sensors and pressure sensors. Alumina ceramic sensors can improve the measurement accuracy and stability of sensors, providing more accurate data support for the control system of automobiles.
Requirements for Alumina Ceramics in New Energy Vehicles
With the continuous development of electric vehicle technology, higher requirements have been imposed on the performance and processing of alumina ceramics. High strength and toughness: During the operation of new energy vehicles, they will be subjected to various complex stresses, so alumina ceramics are required to have sufficient strength and toughness to cope with various complex working environments. High heat resistance and corrosion resistance: During the operation of new energy vehicles, a large amount of heat is generated, and they will also come into contact with various chemical substances, so alumina ceramics are required to have high heat resistance and corrosion resistance. Good processing performance: Due to the large amount of mechanical processing required in the manufacturing process of new energy vehicles, alumina ceramics—such as machinable alumina ceramic—are required to have good processing performance to facilitate manufacturing and assembly. In the first half of 2023, the Chinese new energy vehicle market maintained a relatively fast growth rate, with production and sales exceeding 3.7 million units, a year-on-year increase of over 40%, and a market share of 28.3%. New energy vehicles have become an important part of the Chinese automotive market, demonstrating strong development potential and competitiveness. As new energy vehicle technology continues to develop, there are certain quality requirements for alumina materials, such as the flexural strength of the ceramic matrix (for alumina ceramic base part), impact resistance, fatigue resistance, elastic modulus, electrical insulation performance (for alumina ceramic insulating part), and bonding strength with metalization, etc.
On September 12, 2023, China Powder Network held the "First Electric Vehicle Ceramic Materials Technology Seminar" in Hefei. Manager He Yiwen from Hunan Meicheng Ceramic Technology Co., Ltd. will deliver a presentation titled "Research and Application of Alumina Ceramics in Electric Vehicles", explaining the secrets of alumina ceramics in new energy vehicles to everyone.
