Experimental and theoretical investigation on calcium oxide and L-aspartic as an effective hybrid inhibitor for aluminum-air batteries

Anti‐corrosive additives for alkaline electrolyte in Al‐air batteries: NH4VO3 and polyoxometalates

“…[ 18 ] The combination of ZnO and carboxymethyl cellulose (CMC) for Al5052 alloy in an alkaline medium resulted in a synergistic effect with a considerable decrease in the evolution of H 2 . Some other organic compounds that have been used are plant extracts, [ 19 ] oil, [ 20 ] methanol, [ 21 ] agar, [ 22 ] carboxylic acids, [ 23 ] l ‐aspartic mixed with CaO, [ 24 ] and l ‐cysteine combined with cerium. [ 25 ]…”

Thiophene derivatives as corrosion inhibitors for 2024-T3 aluminum alloy in hydrochloric acid medium

“…The use of 2024-T3 aluminum alloy is well known in aerospace, automotive, marine, and chemical applications due to its high strength/weight ratio and low cost. [1][2][3][4][5][6][7][8] Aluminum is generally protected by a natural Al 2 O 3 lm on the alloy surface in nonaggressive environments. 4 The oxide layer has many defects or pores and can be easily destroyed by corrosive OH À or Cl À ions.…”

Inhibition Effect and Mechanism of Na2SnO3‐Ethylene Glycol Hybrid Additives on 1060 Aluminum in Alkaline Aluminum‐Air Batteries

“…It can be seen from Figure 3 and Table 2 that the radius of the high frequency capacitive arc and the charge transfer resistance and polarization resistance increased with the addition of additives. This means that the addition of a corrosion inhibitor can improve the charge transfer resistance (Rct 1 ) of aluminum and significantly inhibit the self‐corrosion of aluminum through physical or chemical adsorption on the surface of the electrode [19] …”

“…Currently, zinc oxide (ZnO), [18] calcium oxide (CaO), [19] and Na 2 SnO 3 [20] are commonly used inorganic corrosion inhibitors. They act by forming metal monomers in the electrolyte solution that attach to the surface of the aluminum electrode, slowing down the corrosion reaction [21] .…”
