The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work. To balance the flow of electrons, charged ions also flow through an electrolyte solution that is in contact with both electrodes.
When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
If we look at a simple battery and lamp circuit. To illuminate the lamp we need electrons to flow through it. The battery is going to provide the pushing force which allows the electrons to flow through the lamp. We simply need to connect the lamp across the positive and negative terminals of the battery to complete the circuit.
Batteries produce DC electricity or Direct current. This means the electrons flow in just one direction from the negative to the positive. An oscilloscope will show DC as a flat line in the positive region. You can think of DC electricity like a river which flows in just one direction.
We are performing similar studies in our laboratories for batteries. We have already identified one source of increased noise to be uneven discharge of lithium metal . Our work is a first step towards understanding one such mechanism, surely there are many more to be identified.
The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current. battery: A device that produces electricity by a chemical reaction between two substances. current: The time rate of flow of electric charge.

Electric current
On the other hand, holes (positive charges) move from positive end of the battery to the negative end of the battery. So the holes (positive charges) current direction is from positive to negative. The conventional current direction is from positive to negative (same as the current direction of positive charges). The charge of a positively charged particle (hole) is equal to the charge of a ...
