In the field of new energy, acetylene black is applied in lithium-ion battery systems due to its unique branched chain structure, high degree of graphitization, and high purity. The ability to construct a complete electron/ion conduction network between the positive and negative electrodes of a battery is a key auxiliary material to ensure the performance of the electrodes.

Supercapacitors: The addition of carbon black in supercapacitors can, on the one hand, play a conductive role and increase the high rate working performance. On the other hand, the specific surface area of carbon black is relatively large, which can effectively increase the contact area between the electrode material and the electrolyte, increase the specific capacity, and enhance the electrochemical performance of capacitors.
