When I use the Carbon black as conductive agent will the presence of black carbon as a conductive additive in battery's electrode formulation can affect the overall capacity and performance of the batter when calculating the C rate? should I consider the total capacity of the electrode mixture, which includes both the (active material + black carbon) Or neglects and does not calculate whatever its percentage was?
And if I should consider carbon black theoretical capacity, what is the theoretical capacity of it for both sodium and Lithium.
Among them, you choose a method to follow. And during your manuscript/dissertation writing, you should mention how you calculate, based on the total mass or mass of active materials only.
The fact that the carbon black additive is also electrochemically active is usually ignored, presumably because the trend is to only discuss the (intentionally) active material. Even if the focus of your study is the carbon black, expect peer reviewers to focus only on characterisation and specific capacity of your active material as if the carbon black doesn't matter (this happened to me - and the active material was purchased from a large commercial supplier). It would be nice to see this myopia change in the battery research community.
Concerning the sodiation capacity of carbon black, I found it here: Article Carbon black: A promising electrode material for sodium-ion batteries
Just keep in mind that the calculation for theoretical capacity doesn't include any of the actual energy barriers associated with the electrolyte.
Thanks Anne Sawhney and An-Giang Nguyen for your reply. I appreciate it.
