Specific applications 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, plays a vital role in the field of new energy vehicles.
1 Application in batteries
01 Electrolyte materials
The performance and safety of electric vehicle batteries depend largely on the properties of the electrolyte material. Among them, alumina ceramic electrolyte is considered to be one of the key factors because it has high ionic conductivity and high temperature resistance, which can effectively improve the safety and energy density of batteries. Currently, researchers are working on improving the microstructure of alumina ceramic electrolytes and optimizing ion channels to further improve their ionic conductivity and stability.
02 Battery separator
In electric vehicle batteries, the separator is another crucial component. Its main function is to effectively separate the positive and negative electrodes to prevent short circuit events. Alumina ceramic separators have many advantages, such as high strength, high toughness and high chemical stability, which can significantly improve the service life and safety of batteries. In addition, the alumina ceramic separator also enables fast charging, thereby improving the charging efficiency of the battery.
03 Battery negative electrode material
In electric vehicle batteries, the negative electrode material is another key component, which plays a decisive impact on the energy density and charge and discharge efficiency of the battery. Alumina ceramic anode materials have many advantages, including high capacity and excellent cycle performance. These characteristics can effectively improve the charge and discharge efficiency and service life of batteries. In addition, alumina ceramic anode materials also have excellent corrosion resistance and high temperature stability, which can provide more reliable safety performance for batteries.
2 other applications
01 car brake disc
Alumina ceramic brake discs have many excellent properties, including high strength, excellent wear resistance and corrosion resistance. These features can effectively improve the stability and safety of the braking system. In addition, alumina ceramic brake discs also have excellent thermal stability and can withstand high-temperature friction, reducing friction loss during braking, thus improving the reliability and service life of the braking system.
02 Automobile sensors
Alumina ceramic sensors have many excellent properties, including high sensitivity, excellent stability and corrosion resistance. These characteristics make alumina ceramic sensors widely used in various automotive sensors, such as temperature sensors, pressure sensors, etc. The application of alumina ceramic sensors can improve the measurement accuracy and stability of the sensor and provide more accurate data support for the car’s control system.
New energy vehicle requirements for alumina ceramics
With the rapid development of electric vehicle technology, higher requirements have been placed on the performance and technology of alumina ceramics.
1. High strength and toughness: New energy vehicles face various complex stress conditions during operation, so alumina ceramics are required to have high enough strength and toughness to cope with various complex working environments.
2 High temperature resistance and corrosion resistance: New energy vehicles generate a lot of heat and are exposed to various chemicals, so alumina ceramics are required to have high temperature resistance and corrosion resistance.
3. Good processing performance: Since the manufacturing process of new energy vehicles requires a lot of mechanical processing, alumina ceramics are required to have good processing performance to facilitate manufacturing and assembly.
As of the first half of 2023, China’s new energy vehicle market has maintained a rapid growth momentum, with production and sales exceeding 3.7 million vehicles, a year-on-year increase of more than 40%, and the market share reaching 28.3%. New energy vehicles have become an important part of China’s automobile market, showing strong development potential and competitiveness. With the continuous advancement of new energy vehicle technology, the quality requirements for alumina materials are also constantly increasing, including the flexural strength, impact resistance, fatigue resistance, elastic modulus, electrical insulation properties and combination with metallization of the ceramic matrix. Strength, etc.
