Experiment - Making an aluminium-air battery

Students make a working battery out of a piece of aluminium foil, some salt water, a piece of paper towel and some ground charcoal. The voltage can be measured with a voltmeter. Several batteries in a row will light an LED.

A group of undergraduate students in the School of Life and Environmental Sciences, Deakin University, have also prepared some amazing videos on how to conduct these experiments. A big thank you to our students Jayde Kayla Farrugia, Hamish Glenn McManus, Hanan Katrib, Eliza Jane Leskie and Alexandra Tsapi.
