1. Container-a steel can housing the cell’s ingredients to form the cathode collector, a part of the electrochemical reaction.

2. Negative Current Collector-a brass pin in the middle of the cell that conducts electricity to the outside circuit.

3. Electrodes-where the electrochemical reaction takes place.

4. Cathode is manganese dioxide mixture and carbon. Cathodes are the electrodes reduced by the electrochemical reaction.

5. Anode-powdered zinc metal. Anodes are the electrodes that are oxidized.

6. Electrolytes are a potassium hydroxide solution in water. Electrolytes are the medium for the movement of ions within the cell and actually carry the ionic current inside the battery.

7. Separator is a non-woven, fibrous fabric that separates the electrodes and holds the electrolyte between electrodes.

How is a battery built? It all starts with an empty steel ca

As the battery is used and the zinc (anode) oxidizes, the manganese dioxide (cathode) is reduced. Interaction between the zinc and the electrolyte produces reaction products, which gradually slows the cell’s action and lowers its voltage. At the same time, the available manganese dioxide depletes, becoming less and less active as a cell cathode. These factors combine to cause a gradual drop in a battery’s working or operating voltage. Gradually, it dies out and needs to be recharged or disposed immediately.

So, how does it produce electricity? The chemical reaction starts when you insert a battery into a device and complete the circuit. A battery produces power through a chemical reaction. Most chemical reactions produce energy in the form of heat, but by confining chemicals inside the container and controlling the resulting reaction with a separator, batteries produce electrical energy.

The electrolyte oxidizes the anode’s powdered zinc. The cathode’s manganese dioxide/carbon mix reacts with the oxidized zinc to produce electricity. The collector conducts the electric current out of the battery to an external circuit.
