what happens to electrons when they reach the positive post?

Question

My understanding of batteries is that chemical reactions inside of them produce electrons than then flow through the electric circuit and to the positive post. What happens to those electrons when they reach the positive post?

Answer 1

They get scooped up into the electrolyte and pumped back to the negative end. This process continues until the voltage gets high enough that the electrolyte can no longer shuffle the electrons over. Then, the process stops – this only happens when current stops flowing.
