Application of acetylene carbon black in lithium ion batteries

With the rapid growth of global demand for renewable energy and electric vehicles, new energy batteries have become an important pillar of modern technology and industry. The development of battery technology not only depends on the improvement of battery materials, but also includes the optimization of auxiliary materials. As a high-performance conductive additive, acetylene carbon black plays an important role in the new energy battery industry.

Lithium-ion batteries are one of the most widely used rechargeable batteries on the market today and are widely used in portable electronic devices, electric vehicles and energy storage systems. The application of acetylene carbon black in lithium-ion batteries is mainly reflected in the following aspects:

1. Positive electrode material: acetylene carbon black, as a conductive additive, is widely used in positive electrode materials (such as lithium iron phosphate, lithium nickel cobalt manganate, etc.). Its high conductivity can improve the conductivity of the positive electrode material and enhance the rate performance and capacity of the battery.

2. Negative electrode materials: In negative electrode materials (such as graphite, silicon-based materials, etc.), the addition of acetylene carbon black can improve the conductivity of the material and increase the cycle life and energy density of the negative electrode.

3. Electrolyte additives: acetylene carbon black as an additive in the electrolyte, can improve the conductivity and stability of the electrolyte, and further improve the overall performance of the battery.
