Encourage them to use the diagram, the equations, and their explorations to build. (See step #5) The standard procedure for making the aluminum air battery is as follows: Put a 6-inch square of paper towel on top of the aluminum. Offset the position of the paper towel 1-2 inches from the aluminum.
Working Principle: The aluminum air battery working principle involves the reaction of aluminum with oxygen in the presence of an electrolyte, producing electrons that flow through an external circuit.
Aluminum air batteries solve this problem by using air as the cathode, making them much lighter. In an aluminum air battery, aluminum is used as an anode, and air (the oxygen in the air) is used as cathode. This results in the energy density – i.e. energy produced per unit weight of the battery – very high compared to other conventional batteries.
When a full circuit is formed with the aluminum air battery as shown in Figure 1 below, the redox reaction spontaneously begins due to the chemical potential difference between the two electrodes and forces the battery to discharge. Here the aluminum electrode is the anode of the cell since it hosts the oxidation half-reaction.
