Notes

Aluminum-air batteries are a type of metal-air battery that uses aluminum as the anode and ambient oxygen as the cathode. During discharge, the battery consumes aluminum and water while gaining mass from the reaction products.

Definitions

‘Ragone Plot’: Graph showing the relationship between specific power and specific energy, characterized by constants that define the performance envelope
‘Mass Gain Factor’: Rate at which the battery gains mass during discharge due to the conversion of aluminum to aluminum hydroxide
