Carbon black is an extremely versatile substance which is making an increasingly valuable contribution to the automotive industry. Imerys is the leading supplier of highly conductive carbon-based solutions for conductive carbon black used in lithium-ion batteries powering electric vehicles and consumer electronics.
This study used alternative conductive carbon materials (Super P) as the active material content to enhance the conductivity and compatibility of the cathode in lithium-ion batteries. The adhesion test indicates that when the amount of Super P increased to 5.5%, the ASTM grade could still reach 3B.
Conclusions Carbon black is one of the main components of the conductive binder domain in lithium-ion batteries. The selection of different carbon blacks as the conductive agent can result in a discharge capacity with a difference of 1.3–3.8 times.
One way to improve the former is to reduce the binder and conductive additive content. Carbon black is an important additive that facilitates electronic conduction in lithium-ion batteries and affects the conductive binder domain although it only occupies 5–8% of the electrode mass.
Conclusion C-NERGY™ Super C45 and C-NERGY™ Super C65 are suitable conductive carbon blacks for electrodes in advanced lithium ion batteries. Both carbon blacks decrease the electrical resistivity of standard LiCoO 2 electrodes to a similar level outperforming most of the existing low surface area conductive carbon blacks.
