Carbon properties such as compressibility and polymer binder absorption affect the mechanical stability of the electrode, and thus the electrode manufacturing process and production yield. Carbon conductive additives are applied in both the positive and the negative electrode of commercial lithium ion batteries.
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.
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.
