In the long-term operation, the battery performance can be enhanced by supplying fresh electrolyte into the anolyte and catholyte. When the volume of electrolyte is sufficient, the battery can discharge for a longer time while maintaining a constant discharge voltage until the aluminum anode is fully consumed.
The electricity is generated through oxidation and reduction reaction within the anode and cathode. Among various types of metal-air battery, aluminum-air battery is the most attractive candidate due to its high energy density and environmentally friendly.
A new technique for suppressing corrosion means you don’t need to choose between long shelf life and solid performance. An aluminum–air battery sandwiches a circulating aqueous electrode between an aluminum anode and a cathode in contact with ambient air.
Due to the open battery configuration of metal–air batteries, the oxygen reagent can be directly received from the surrounding air instead of prior incorporation, thus contributing to their very high theoretical energy densities . Table 1. Parameters of various metal–air batteries.
Alternatively, metal–air batteries such as Al–air batteries are a combination of both battery and fuel cell components. In these batteries, the anode consists of a solid metal electrode (Al), while the cathode utilizes the oxygen present in the air.
The aluminum–air battery is considered to be an attractive candidate as a power source for electric vehicles (EVs) because of its high theoretical energy density (8100 Wh kg −1), which is significantly greater than that of the state-of-the-art lithium-ion batteries (LIBs).
