The lowest corrosion rate means that the use of Al as an electrode for discharge in alkaline battery applications is the highest; accordingly, the discharge capacity is the most significant 20. It is possible to state that when the corrosion process is fully stopped, the capacity of aluminum as an anode rises to its theoretical value (2.98 h/g).
So, the present results can be a novelty in alkaline batteries' electrochemical efficiency. The lowest corrosion rate means that the use of Al as an electrode for discharge in alkaline battery applications is the highest; accordingly, the discharge capacity is the most significant 20.
However, this beneficial voltage range is typically achieved when using alkaline electrolytes. Regrettably, the use of such alkaline electrolytes is associated with a significant drawback: it exacerbates the corrosion of the aluminum anode, which can substantially affect the battery's performance and overall lifespan.
