| description | The electrochemical performance of Al-air cell employing seawater and NaCl electrolyte
of various concentrations has been investigated. The open circuit voltage and discharge capacity of
the cell correlate well with the electrolyte conductivity data. Using 4 M NaCl electrolyte which
possesses the highest conductivity, the Al-air cell registers an open circuit potential (OCV) of 1.1 V
and demonstrates discharge capacity of 250 mAh, rated at 1 mA. Upon employing seawater, the
OCV reduced to 0.68 V and discharge capacity decreased to 150 mAh. However, utilizing an
exposed cell configuration which mitigates the hydroxide gel water binding effect, the Al-air
seawater cell performance is greatly enhanced until almost compatible to Al-air cell employing 4 M
NaCl. |
