Metal–Air Batteries with High Energy Density: Li–Air versus Zn–Air

“…[ 128 ] Zhang et al suggested that introducing metallic bismuth to a pasted zinc electrode improved the discharge performance because of the formation of an electronic conductive material. [ 129 ] Another method of suppressing hydrogen evolution is to coat the zinc metal with other materials; Cho et al suggested that the zinc surface coated with Li 2 O-2B 2 O 3 (lithium boron oxide, LBO) could increase discharge capacity and decrease hydrogen evolution. It is believed that the coating layer prevents the zinc surface from facing the alkaline electrolyte directly, which enables the zinc to avoid side reactions in the cell.…”

Effect of Y Addition on the Semi-Solid Microstructure Evolution and the Coarsening Kinetics of SIMA AZ80 Magnesium Alloy

“…This process 46 mainly includes two steps [, namely,] cold or hot deformation and subsequent partial remelting in the semi-solid [temperature] range. It was reported from the previous literature that more spherical 48 structure in AZ91D alloy semisolid slurry was obtained by the compression pre-deformed process as 49 SIMA process [14]. Many researches also introduced severe plastic deformation (SPD) to be another 50 effective SIMA approach for producing the semi-solid feedstock.…”

Synthesis and Characterization of Nanosized Calcium Zincate Powder and it Application to the Zn Electrodes

“…The secondary Zn electrode of Zn-air batteries (1)(2)(3)(4)(5)(6)(7)(8) has advantages of high specific energy, low cost, and environmental friendliness. However, the use and development for a secondary Zn electrode on rechargeable battery are still limited because of the dendritic growth, shape change, and high solubility of zinc discharge product in a concentrated alkaline KOH solution.…”

“…Recently, some authors (18)(19)(20)(21) Besides, the electrochemical performances of the secondary Zn pasted electrode are studied through a galvanostatic charge/discharge measurement. As we know, the major effect on the electrochemical properties of the secondary Zn pasted electrode is the chemical composition of the electrode.…”

“…The addition of Ca(OH) 2 compound into the Zn pasted electrode can significantly reduce the shape change and the formation dendritic deposits. In fact, the life-cycle of the secondary Zn pasted electrode composed of calcium zincate powders [18][19][20][21] is greatly extended.…”
