In a battery, the electron flow from the reducing agent to the substance being reduced creates an electrical current. This redox reaction occurs within what is called an electro-chemical cell.
Oxidation and Reduction
The idea that oxidizing agents and reducing agents are linked, or coupled, is why they are called conjugate oxidizing agents and reducing agents. Conjugate comes from the Latin stem meaning "to join together." It is therefore used to describe things that are linked or coupled, such as oxidizing agents and reducing agents.
Redox
