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.
The confusion here is from the initial poor description of how a battery works. A battery consists of three things: a positive electrode, a negative electrode, and an electrolyte in between. The electrodes are made of materials that strongly want to react with each other; they are kept apart by the electrolyte.
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
When you add a wire between the ends of the batteries, electrons can pass through the wire, driven by the voltage. This reduces the electrostatic force, so ions can pass through the electrolyte. As the battery is discharged, ions move from one electrode to the other, and the chemical reaction proceeds until one of the electrodes is used up.
Thinking about two batteries next to each other, linked by one wire-- there is no voltage between the two batteries, so there is no force to drive electrons. In each battery, the electrostatic force balances the chemical force, and the battery stays at steady state.
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.

Diode Current Flow: Functionality and Characteristics
Diode Current Flow Functionality. A standard diode requires a precise amount of forward voltage before it permits the flow of current. In general, the specified amount of voltage a diode requires before allowing the current to flow is minute. Typically, this equates to 0.5 volts. Until it achieves this voltage amount, the current will not flow ...

Which Way Does Electricity Flow?
If the battery was connected the other way around, it was also observed that no current would flow. This current, flowing from the hot filament, through the vacuum, to the electrode, was invisible. No practical purpose could be found for the discovery, but Edison patented this "Edison Effect" anyway.

Thank you. Displacement current just refers to the fact that electric field changes in time as capacitor is being charged which has an effect of creating a magnetic field according to Ampere''s law just like a real current does.
