For the lithium-ion cells, what determines the OCV (open circuit voltage) of a fresh assembly half coin cell? how much must it be for anode type active materials and cathode type active materials?
If it depends on the amount of electrolyte we use to fill a coin cell (2032 coin cell)?
I recommend you to read the following textbook. The answer to your question is in Chapter 2.

An-Giang Nguyen Thank you very much for your suggestion.
There is still a question for me: when we make coin cells, even for the same material, each cell shows a different voltage (just measure with voltmeter after assemble them), which I guess depends on practical conditions, not theoretical considerations.
For example, out of 10 coins assembled from an active material, most of them show a voltage ~3 volts, but some are below 2 volts, I can't understand what is the meaning of this difference?
(In this example, the cells have lithium rich cathode material as working electrode and lithium foil as reference electrode)
