Experiments: Building a Biomass Battery

    Research output: NRELFact Sheet


    This experiment teaches students the basics of a battery. Students can work as individuals or in groups to wire together potato wedges containing a penny and a screw. These materials will act as the anode and cathode of the biomass battery, and when wired together, four potato wedges should produce approximately 3V of electricity. This lesson includes vocabulary like voltage, voltmeter, series circuit, biomass, anode, and cathode. This lesson could easily be scaled up to include vocabulary like reduction and potential reactions.
