Substrate induced coagulation (SIC) of nano-disperse carbon black in non-aqueous media: the dispersibility and stability of carbon black in N-methyl-2-pyrrolidinone

Rheological properties and stability of NMP based cathode slurries for lithium ion batteries

“…However, slurries containing micron sized NMC particles also have the capability to form a coagulated structure by the addition of nanoscaled CB particles. CB can be electrostatically stabilized in NMP without additional dispersants as these particles are charged by counterions from dissociating surface groups [25]. For NMC, on the other hand, the attractive van-der-Waals forces seem to dominate as dispersions without stabilizing agents were found to show intense flocculation tendency.…”

Substrate-induced coagulation (SIC) of nano-disperse alumina in non-aqueous media: The dispersibility and stability of alumina in N-methyl-2-pyrrolidinone

“…In previous work carbon black [2] and titania suspensions [1] in NMP were invesitigated using the same conditions as in this work. The alumina dispersions were less stable than carbon black and titania dispersed in the same media, but stable enough to be handled in the lab and in a SIC process.…”

“…Recently, aqueous as well as non-aqueous titania dispersions were investigated for the use in a SIC process [1] . SIC can also be performed in non-aqueous media to coat materials that are sensitive to hydrolysis [2–4] . In the past it has also been used to, e.g.…”

Chemical modification of carbon black by a simple non-liquid-phase approach

“…Quasi-graphitic structure, complex configurations, and colloidal dimensions of pristine CB result in its poor dispersibility in media or other materials. Therefore, to improve the dispersibility and stability of CB, chemical modification is an important and challenging research area [6].…”
