“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that’s what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
As shown in the figure, the direction of current flow is opposite to the direction of electron flow. The battery continues to discharge until one of the electrodes is used up [3, p. 226]. Figure 9.3.3: Charge flow in a charging battery. Figure 9.3.3 illustrates the flow of charges when the battery is charging.
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
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.
Figure 9.3.3: Charge flow in a charging battery. Figure 9.3.3 illustrates the flow of charges when the battery is charging. During charging, energy is converted from electrical energy due to the external voltage source back to chemical energy stored in the chemical bonds holding together the electrodes.
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.
