Aniruddh Chennapragada , Year 12 , James Ruse Agricultural High School , Investigating the Carbonisation and Activation of Banana Peels for Applications in Batteries
Aniruddh successfully prepared activated carbon from banana peel . His project then went on to characterise the activated carbon synthesised with FT-IR spectroscopy and SEM . Finally , he used his activated banana peels as cathodic material in an aluminium air battery proving it is an effective material for use in battery technology showing that there is great potential for utilising organic waste like banana peels for preparing chemically activated materials that have applications in energy technology .
