“…In the case of hybrid Liair cells, it is not uncommon to see that the current catalyst R&D is heavily resorted to the conventional catalysts developed (or being developed) for other metalair batteries (or fuel cells): The control of morphology and orientation of crystal plane and its defect sites. 75,89,[173][174][175][176][177] Still, in many cases platinum (Pt) is considered and adopted as the best catalyst, 176) although there are many reasons to devote research to developing cost-effective alternatives (e.g., perovskites, spinels, and pyrochlores 20) from the commercialization standpoint.…”

ABSTRACT:Li-air cell is an exotic type of energy storage and conversion device considered to be half battery and half fuel cell. Its successful commercialization highly depends on the timely development of key components. Among these key components, the catalyst (i.e., the core portion of the air electrode) is of critical importance and of the upmost priority. Indeed, it is expected that these catalysts will have a direct and dramatic impact on the Li-air cell's performance by reducing overpotentials, as well as by enhancing the overall capacity and cycle life of Li-air cells. Unfortunately, the technological advancement related to catalysts is sluggish at present. Based on the insights gained from this review, this sluggishness is due to challenges in both the commercialization of the catalyst, and the fundamental studies pertaining to its development. Challenges in the commercialization of the catalyst can be summarized as 1) the identification of superior materials for Li-air cell catalysts, 2) the development of fundamental, material-based assessments for potential catalyst materials, 3) the achievement of a reduction in both cost and time concerning the design of the Li-air cell catalysts. As for the challenges concerning the fundamental studies of Li-air cell catalysts, they are 1) the development of experimental techniques for determining both the nano and micro structure of catalysts, 2) the attainment of both repeatable and verifiable experimental characteristics of catalyst degradation, 3) the development of the predictive capability pertaining to the performance of the catalyst using fundamental material properties. Therefore, under the current circumstances, it is going to be an extremely daunting task to develop appropriate catalysts for the commercialization of Li-air batteries; at least within the foreseeable future. Regardless, nano materials are expected to play a crucial role in this field.

“…In an effort to address the limitation of the current zinc-air battery, several researches were made to find a catalyst that can effectively catalyze both the ORR and OER; such catalysts are termed bifunctional catalyst. Pt and Pt-Ru catalysts have shown the highest catalytic activity for ORR and OER but, because of their high cost and other drawbacks, non-noble metal catalysts such as perovskites are preferred, among which La1-xSrxCoO3 exhibits the highest catalytic activity [8][9][10][11] .…”

>> Various commercially available gas diffusion layers (GDLs) from different manufacturers were used to prepare an air electrode using La0.8Sr0.2CoO3 perovskite (LSCP) as the catalyst for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in an alkaline solution. Various GDLs have different physical properties, such as porosity, conductivity, hydrophobicity, etc. The ORR and OER of the resulting cathode were electrochemically evaluated in an alkaline solution. The electrochemical properties of the resulting cathodes were slightly different when compared to the physical properties of GDLs. Pore structure and conductivity of GDLs had a prominent effect and their hydrophobicities had a minor effect on the electrochemical performances of cathodes for ORR and OER.

The template‐free synthesis of zinc nanowires was achieved from Zn(TfO)2 in 1‐butyl‐1‐methylpyrrolidinium trifluoromethylsulfonate ([Py1,4]TfO) at 125 °C. The electrodeposition process was evaluated by using cyclic voltammetry. The electrodeposited zinc was characterized by using scanning electron microscopy (SEM) and X‐ray diffraction. SEM images indicated that the zinc deposits on gold contain nanowires of varying lengths, ranging from approximately 400 nm to 1.2 μm, whereas intertwined nanowire structures were observed on indium tin oxide (ITO) from the same solution. A similar kind of intertwined nanowire structure was also observed on both gold and ITO from ZnCl2/[Py1,4]TfO at the same temperature. The results show that zinc nanowire structures can be achieved from ionic liquids without a template at elevated temperatures.
