During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode. According to Ohm’s law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential.
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
Editor’s note, 2/13/2020: Per reader requests, we have uploaded model files to go along with this blog post to the Application Gallery entry “ Potential Profile in Batteries and Electrochemical Cells “. We find out if the electric currents in batteries flow backwards by studying the potential profile inside a battery.
Batteries are designed so that the energetically favorable redox reaction can occur only when electrons move through the external part of the circuit. A battery consists of some number of voltaic cells. Each cell consists of two half-cells connected in series by a conductive electrolyte containing metal cations.
The easiest way to think of it is this: Current will only ever flow in a loop, even in very complex circuits you can always break it down into loops of current, if there is no path for current to return to its source, there will be no current flow. In your battery example, there is no return current path so no current will flow.
With this analogy, it is plainly obvious why both the positive and negative ends of a battery must be connected in a circuit. If, say, you connect only the negative electrode to ground, there is no current because there is no electricity coming in on the positive electrode that can be pumped out.
