“…Metal–air batteries can be operated in both aqueous and organic media, and meanwhile different metals could be utilized as anode materials. So far, Li–air batteries, Na–air batteries, Mg–air batteries, Zn–air batteries, and Al–air batteries are progressively explored in both aqueous and aprotic electrolytes, wherein the Li–air configuration affords the highest theoretical capacity . The primary aqueous Zn–air batteries have been commercialized in medical applications, e.g., hearing‐aid cells, and Al–air and Mg–air batteries are mainly employed in the military realm.…”

“…Many oxides, e.g., titanium dioxide, are able to deliver efficient catalytic performance with fairly good stability . The amorphous TiO 2− x with isotropic nature and abundant oxygen deficiency contained both Ti 3.5+ and Ti 3+ , demonstrating discharge and charge capacities of 11 000 and 9200 mAh g −1 , respectively, at a current density of 300 mA g −1 in the Li–air batteries with the enhanced cycling stability of 90 cycles as well . Other metal oxides based on the early transition metals of group VII and VIII elements (e.g., Fe, Co, Ni, and Mn) are also widely studied as cathode materials in both aqueous and nonaqueous batteries.…”

possess lower hardness, higher strength, higher elasticity, higher tensile strength, lower internal energy, higher interatomic forces, lower viscosity coefficient, larger surface area, higher chemical stability, and strong corrosion resistance compared with their crystalline counterparts. [1][2][3] Based on the anionic constituents, amorphous materials could be categorized as oxides, sulfides, phosphates, etc. Among them, amorphous metal oxide family is of great importance owing to its widespread applications in a variety of areas such as batteries, supercapacitors, electronics, conducting films, multilayered transistors, electrochromic displays, nonvolatile memories, and the like. [4][5][6] As the basic building blocks, metaloxide (M-O) polyhedra are responsible for the essential features of the electronic band structure in amorphous metal oxides (AMOs). [3] AMO materials differ from their crystalline counterparts in the arrangement of M-O polyhedra, in which a random network arrangement of distorted polyhedra with short-range ordering is presented rather than maintaining perfect periodicity. [7,8] The coordination number of the M-O polyhedra, namely, the number of anions bonded to the metal cation, constitutes a crucially decisive factor for the unique properties of AMOs. Multiple polyhedra are interconnected through different types of sharing configurations known as edge sharing, corner sharing, and face sharing of the oxygen atoms. The combination of different sharing geometries also affects the properties of AMOs. [9] In other words, AMOs are formed by the superposition of the distorted M-O polyhedra to form network arrays through a random package. Long-range structural disorder in the AMO reduces scattering mean free path, and the lack of grain boundaries makes the electronic properties identical within large areas. These unique characteristics make them suitable for flexible electronics such as flexible films, intervening layers, thin film transistors, etc. [10][11][12] In recent years, there are numerous reports pointing out the advantages of AMOs over the crystalline counterparts in many electrochemical applications. [13][14][15][16][17] For example, the inherent disorderliness in the structural arrangement and rich defects are evidenced to be highly constructive to improve the alkali ion diffusion through the lattice. [18,19] As for intercalation-type electrodes in lithium-ion batteries (LIBs), amorphous materials Amorphous metal oxides (AMOs) have aroused great enthusiasm across multiple energy areas over recent years due to their unique properties, such as the intrinsic isotropy, versatility in compositions, absence of grain boundaries, defect distribution, flexible nature, etc. Here, the materials engineering of AMOs is systematically reviewed in different electrochemical applications and recent advances in understanding and developing AMO-based high-performance electrodes are highlighted. Attention is focused on the important roles that AMOs play in various energy storage and conversion technologies...

“…Previously, we have conducted a comprehensive account [18] on the efforts of ALD and MLD for better Li-S batteries and readers may refer to it for more details. On the oxygen cathodes of Li-O 2 batteries, ALD has mainly been used for depositing nanoscale catalysts [19,143,144] in several studies. In comparison, currently, there has an increasing number of studies on Li metal anodes, focusing on addressing dendritic growth and SEI formation.…”
