This question will probably sound easy to most of you, but to me, it is still a kind of magic 🙂
Taking in account all I know until know, I guess a battery has two sides:
- one that "emits" electrons (any technical term for that ?)
- one that "lacks" electrons
So how can it be that when I put two batteries in series, they voltage adds up ? To me it sounds like the electrons from one should flow directly among the protons of the other.
Obviously there must be some kind of black magic there 😉 Will one of you sorcerers explain it to me ?

A cell or a battery is essentially a charge "pump". Now, to help form an intuition for the answer to your question, fall back to the hydraulic analogy.
Two water pumps in parallel can produce twice the water flow of one (ideally).
Two water pumps in series can produce twice the pressure (or head) of one (ideally).
