When you push on one end of a stick, that push is carried to the far end of the stick almost instantly. The stick itself has barely moved.
Electricity moves like the force on the stick. In fact, it moves way faster. The actual electrons move very slowly.
Capacitors charge almost instantly. If not for some other component limiting them, they *would* charge instantly.
Batteries are limited by the chemicals in them. These chemicals rearrange themselves to store the charge, and if you force this too fast the battery just destroys itself. This is not a limitation with electricity, but with battery chemistry.
