We prepared cathodes with various types of activated carbon and measured the cathodes’ electrochemical performance according to the kind of
activated carbon. Activated carbon supplies airflow channels and reaction sites in the cathode of zinc air batteries. When we use activated carbon
with a high specific surface area as the cathode’s catalyst substrate, we expect high electrochemical performance because this type of carbon
provides more air flow channels and reaction sites.
We focused on investigating the relationship between the cathode’s pore structure and its electrochemical characterizations.We also studied the
effects of the various activated carbon materials on the zinc air batteries’ performance. Increasing the macropores or mesopores in the activated
carbon resulted in achieving more power from the battery.
