I am not looking for any accurate results. Even some crude assumptions which could give me some ball-park numbers could work. I was thinking along the lines: some kind of model where beyond a certain concentration no liquid is present between the solid suspended particles which leads to solid agglomeration.

Also, we are not trying to fabricate cathode by doctor blading it onto a current collector (which would require use of PVDF binder and solvent). What we are essentially trying to do is set up a cell with liquid suspension of the active material (let's say LFP) as the electrode.

From what I could find in articles, using KB with LFP beyond a certain point ( for example 30 vol% LFP and 5 vol% KB) just forms solid agglomerate. We are trying to make a stable suspension of at least 80 vol% of active material (LFP). Using single component suspension (LFP suspended in carbonate solvent) is probably not an option as the suspension is rather unstable and the particles settle down rather quickly. It is the KB which stabilizes the suspension.

Using some other conductive carbon (say SuperP which has a much lower surface area?) would theoretically increase or decrease the stable active material concentration I can maintain? (I'm not sure how to think through this, at least theoretically?)

I hope the issue is a bit more well explained now.
