That's true in a sense, but it's a rather tortured sense. The chemical action 'produces' (at one end, 'consumes' at the other) electrons to (and from) the electrodes. But the reactions also point to a specific electrochemical, and thus electrical, potential.

It should be fairly obvious that the chemistry in a battery doesn't have any direct dependency on the resistance of the external circuit. What the resistance does is determine (in combination with the voltage) a rate limit on the flow of electrons which is (under typical conditions) the rate-limiting step in the battery reactions.
I don't know any 3e, so there is no chance that I am talking about 3e rules by accident.
