Dec 13, 2024| Applications of Acetylene Carbon Black in Multiple Fields
1. Field of Lithium-ion Batteries
Acetylene carbon black plays a crucial role as a conductive agent in the positive and negative electrode materials of lithium-ion batteries. It can build an efficient conductive network, greatly accelerate the movement of electrons, effectively reduce the internal resistance of the battery, and significantly improve the charging and discharging efficiency as well as the power density. For example, when added to the lithium iron phosphate positive electrode, the conductive performance of the battery can be optimized, and the output efficiency during the discharging process can be greatly enhanced.
2. Field of Nickel-metal Hydride Batteries
In the negative electrode material system of nickel-metal hydride batteries, acetylene carbon black works in coordination with chromium oxide and the electrolyte. Its developed crystallization and secondary structure endow the material with excellent electrical conductivity and liquid absorption properties. Moreover, it has a low content of heavy metal impurities and can effectively reduce the loss caused by self-discharge, thus strongly improving the performance of the battery and extending its service life.
3. Field of Supercapacitors
As a conductor in supercapacitors, acetylene carbon black significantly promotes the flow of electrons, providing a solid guarantee for the improvement of the performance of supercapacitors, enabling them to perform better in energy storage and rapid charging and discharging.
4. Field of Rubber Products
When acetylene carbon black is incorporated into rubber materials, it can bring about improvements in multiple aspects. It not only endows the rubber with excellent electrical conductivity but also enhances its wear resistance and strength. For example, when an appropriate amount of acetylene carbon black is added to the blend of nitrile rubber and tread reclaim rubber, the resulting rubber products have excellent mechanical properties and a low volume resistivity, which perfectly meet the requirements of conductive rubber products with high demands for mechanical properties.
5. Field of Coatings and Inks
Acetylene carbon black serves as both a black pigment and a filler in coatings and inks. It not only provides a pure black color and good color stability but also imparts special properties such as electrical conductivity, anti-static performance, and ultraviolet resistance to the products, expanding their application range in the field of functional coatings and inks.
6. Field of Lead-acid Batteries
In the manufacturing process of lead-acid batteries, acetylene carbon black is used as a conductive agent in the negative electrode paste. When it is ground together with conductive graphite, it can effectively enhance the electrical conductivity of the negative electrode, thereby promoting the overall performance improvement of lead-acid batteries and ensuring their stable and reliable operation in various application scenarios.
7. Field of Electronic Devices
Acetylene carbon black has a wide range of applications in the manufacturing field of electronic devices. It can be used to construct conductive layers, electrodes, seals and other components. Its stable electrical conductivity and good processing compatibility lay the foundation for the precise and efficient electrical connection and function realization of electronic devices, helping the development of miniaturization and high performance of electronic devices.
