HOME	What is inside a battery?

1. Positive Pip A bump in the bottom of the battery can which shows it is the positive terminal. 2. Steel Can Nickel-plated steel which is made into a container to hold chemicals, and acts as the external circuit. 3. Outer Jacket A plastic sleeve which has the decorations and writing saying what sort of a battery it is. 4. Separator Fibrous and porous material which separates electrodes; holds electrolyte between electrodes. 5. Electrolyte A solution of potassium hydroxide in water which carries the current inside the battery. 6. Cathode Manganese dioxide and graphite which take up electrons from the external circuits. 7. Anode Powdered zinc metal which is where the electrons come from. 8. Anode Collector Tin-plated brass which acts as a path for the electrons going from the anode to the external circuit. 9. Seal/Vent Molded plastic disc which holds internal components inside the cell and releases internal pressure when battery is damaged.
