A review on development of metal–organic framework-derived bifunctional electrocatalysts for oxygen electrodes in metal–air batteries

“…These batteries' primary advantage is that oxygen reduction reactions can be catalyzed by non-noble metals and have a potential specific energy density of 1084 W h kg −1 . 26,27…”

“…These batteries' primary advantage is that oxygen reduction reactions can be catalyzed by non-noble metals and have a potential specic energy density of 1084 W h kg −1 . 26,27 One of the distinguishing features of metal-air batteries is their open cell structure, which uses oxygen gas from the air as the cathode material. Traditional rechargeable batteries have a closed system for their cell arrangement.…”

Investigation of commercial aluminum alloys as anode materials for alkaline aluminum–air batteries

“…[13][14][15][16][17][18][19][20] Among them, metal Al stands out due to its merits of high abundance in the Earth's crust, low cost, and ultra-high theoretical specic capacity (2.9 Ah kg −1 ) and energy density (8100 W h kg −1 ). [21][22][23][24] Hence, aqueous Al-air batteries have been regarded as excellent candidates for underwater power sources, portable energy storage devices, and emergency power supplies. [25][26][27][28] Currently, nding suitable Al anodes with low cost and high performance is urgent.…”

Influence of Ba micro‐alloying on electrochemical and discharge behaviors of Mg‐Al anodes for mg‐air primary battery

“…Low‐cost and clean energy (e.g., solar, tidal, wind, and hydrogen energy) has received widespread attention 3‐5 . Metal‐air batteries are an ideal clean energy source due to their low‐cost, non‐pollution, high theoretical voltage, high specific energy density, and environmental friendliness 6‐10 . Among them, due to the nice theoretical electrochemical properties of Mg, such as relatively negative electrode potential (−2.37 V vs. Standard Hydrogen Electrode, SHE) and a high theoretical capacity (3832 mAh cm −3 ), the primary Mg‐air battery becomes one of a promising energy source 11‐14 .…”

“…non-pollution, high theoretical voltage, high specific energy density, and environmental friendliness. [6][7][8][9][10] Among them, due to the nice theoretical electrochemical properties of Mg, such as relatively negative electrode potential (À2.37 V vs. Standard Hydrogen Electrode, SHE) and a high theoretical capacity (3832 mAh cm À3 ), the primary Mg-air battery becomes one of a promising energy source. [11][12][13][14] However, the self-corrosion and the low anode and cathode kinetics of the Mg-based anode materials in aqueous electrolytes limit further development of Mg-air batteries, which are essentially related to severe materials challenges.…”
