The positive terminal, often represented by a longer line or a plus sign (+), is where the current flows out of the battery. On the other hand, the negative terminal, usually indicated by a shorter line or a minus sign (-), is where the current flows into the battery. These terminals establish the direction of current flow within the circuit.
Electric current
An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface. [1]: 2 [2]: 622 The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor electric circuits the …
In which direction does current flow in an electric circuit?
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.

Internal Resistance and Terminal Voltage. The amount of resistance to the flow of current within the voltage source is called the internal resistance.The internal resistance r of a battery can behave in complex ways. It generally increases as a battery is depleted, due to the oxidation of the plates or the reduction of the acidity of the electrolyte.
DOE Explains...Batteries | Department of Energy
To accept and release energy, a battery is coupled to an external circuit. Electrons move through the circuit, while simultaneously ions (atoms or molecules with an electric charge) move through the electrolyte. In a rechargeable battery, electrons and ions can move either direction through the circuit and electrolyte.

19.2 Series Circuits
The arrow indicates the direction in which positive charge would flow in this circuit. Recall that, in metals, electrons are mobile charge carriers, so negative charges actually flow in the opposite direction around this circuit (i.e., counterclockwise). However, we draw the current to show the direction in which positive charge would move.

What is the direction of the electricity flow in a DC circuit?
$begingroup$ Beginners can be misled by the idea that electrons "flow". In a simple circuit made from say a battery, a lamp, and a switch, each individual electron would take of the order of one hour to make a complete loop around the circuit. The idea that when you flick a light switch in your house, electrons somehow travel instantly down …
How do electrons from a battery move through a circuit?
If the conductors between the terminals of the battery were non-uniform, ie wires and resistors, then the current (charge passing a point per unit time) through each of the elements of the circuit would be the same but the potential difference across each of the components would differ, it being larger across components with larger resistance.
21.2: Electromotive Force
Since (V = emf = -Ir), terminal voltage equals emf only if there is no current flowing. The internal resistance (r) can behave in complex ways. As noted, (r) increases as a battery is depleted. But internal resistance may also depend on the magnitude and direction of the current through a voltage source, its temperature, and even its history.
