“…Current drawbacks such as poor cycle ability 7 and a large overpotential in the charge process 8 need to be overcome for a commercial application of LABs. To improve the cycle performance and lower the charge voltage of LABs, it is important to elucidate the Li-O 2 electrochemical reaction that has the following equation: …”

Non-aqueous lithium-air batteries (LABs) attract attention as a candidate technology for next-generation energy storage devices. It is crucial to understand how the discharge product Li 2 O 2 is formed and decomposed by the electrochemical reactions to improve the cycle performance and decrease the charge voltage, which are the most important subjects for LAB development. Here, operando X-ray diffraction with high-brilliant X-rays in a transmission mode was used to observe the intensity and structural changes of crystalline Li 2 O 2 in an operating non-aqueous LAB in real time, and the Li-O 2 electrochemical reaction involving Li 2 O 2 formation and decomposition was clearly demonstrated. The electrochemically formed Li 2 O 2 , which had an anisotropic domain size of 10 nm in the c-direction and 40-70 nm in the ab-plane, grew due to the increase of the number of domains during the discharge process. No other reaction products with a crystalline phase such as LiOH were found in either the cathode or anode of the LAB, whereas the accelerated decomposition rate of the domains was accompanied with the change of the domain shape and lattice constant of the c-axis in the latter half of the charge process with voltage higher than 4 V.

“…[13][14][15][16] As demonstrated, the incorporation of active cathode catalyst, which can increase the overall energy storage efficiency by accelerating ORR and OER process, makes sense. Currently, many insightful reviews on Li-O 2 battery have been published from various perspectives, [17][18][19][20][21][22] thus providing an excellent starting point for researchers with the desire to explore the Li-O 2 technology. However, the content reported in these reviews doesn't include the latest development regarding electrocatalyst in Li-O 2 battery.…”

In the Li‐O2 field, the electrocatalyst plays an important role in accelerating the sluggish electrochemical reactions, thus improving the performances of Li‐O2 battery. In this field, numerous researches regarding the incorporation of electrocatalyst have been published. With the aim to provide an easy as well as timely access for readers to follow the latest development in the catalyst area, the progress regarding the recent development on the application and research of electrocatalyst for Li‐O2 batteries is reviewed in a comprehensive and systematic manner. The application of various kinds of electrocatalyst including solid catalyst and soluble catalyst is first summarized. Then, relevant research including the catalyst design and the correlation between the catalyst property and the Li‐O2 battery performance is discussed. Finally, insights on how to fabricate an effective electrocatalyst are provided, which are expected to provide guidance for further catalyst design.

“…Currently, the development of these devices has become crucial in order to support decarbonisation targets, for example through battery electric vehicles [5,6]. This development faces many challenges, for instance the need to safely improve battery energy density and cycle life, [7,8,9,10]. Researchers have been working over a decade to solve the problems in metal-air batteries such as life cycle limitation, non-uniform zinc dissolution during charge and discharge cycle [11], morphological changes of the zinc electrode [12] and dendritic growth at the zinc anode [13].…”

Battery electrode microstructures must be porous, to provide a large active surface area to facilitate fast charge transfer kinetics. In this work, we describe how a novel porous electrode scaffold, made from stainless steel 316L powder can be fabricated using selective laser sintering by proper selection of process parameters. Porosity, electrical conductivity and optical microscopy measurements were used to investigate the properties of fabricated samples. Our results show that a laser energy density between 1.50-2.00 J/mm 2 leads to a partial laser sintering mechanism where the powder particles are partially fused together, resulting in the fabrication of electrode scaffolds with 10% or higher porosity. The sample fabricated using 2.00 J/mm 2 energy density (60W -1200 mm/s) exhibited a good electrical conductivity of 1.80 x 10 6 S/m with 15.61% of porosity. Moreover, we have observed the porosity changes across height for the sample fabricated at 60W and 600 mm/s, 5.70% from base and increasing to 7.12% and 9.89% for each 2.5 mm height toward the top surface offering graded properties ideal for electrochemical devices, due to the changing thermal boundary conditions. These highly porous electrode scaffolds can be used as an electrode in electrochemical devices, potentially improving energy density and life cycle.
