Why don''t electrons just "pile up" on the positive side of a battery?
It takes energy to pile up free electrons into one end of the battery since electrons want to repel each other. Naturally, you don''t want this to happen in a battery that you want to keep running since the repulsion of the electrons would quickly reach equilibrium with the the energy being produced by the battery to move them and bring everything to a standstill.
