“…[42,171] For instance, Sun fabricated a np-Ni@NiO/MG electrode by electrochemical alloying Ni 40 Zr 60 MG precursors in HF with different concentration as shown in Figure 14. [167] It is clearly that the np-Ni@NiO/MG with flexibility can be obtained in 0.02 m HF, while the structure www.advancedsciencenews.com with cracks will form in higher concentration. Besides, the relationship between the corrosion rate and the morphology and flexibility of the electrode was also established.…”

Owing to its unique atomic arrangement and electronic structure, metallic glass (MG) has been widely investigated in the field of energy storage and conversion. In the past few decades, multiple strategies have been developed to synthesize bulk and nanosized MG based materials. Here, combining the structure–activity relationship of MG with electrochemical reaction kinetics, the substantial progress of glass structures in electrocatalytic processes are highlighted, including the hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, methanol oxidation reaction, carbon dioxide reduction reaction, and nitrogen fixation. Meanwhile, applications of MG materials in energy storage devices, like supercapacitors and lithium‐ion batteries, are also introduced in detail. Finally, challenges and possibilities for reasonable design of highly‐efficient MG‐based electrode materials are proposed. The integration of high‐throughput methods, artificial intelligence technology, as well as advanced characterization techniques is fundamental to screen materials with remarkable performance. This review aims to deepen the understanding of the relationship between electronic structure and electrochemical performance, providing guidance for rational design of functional MG materials with outstanding activity, selectivity, and durability.

Research and development on electrochemical energy storage and conversion (EESC) devices, viz. fuel cells, supercapacitors and batteries, are highly significant in realizing carbon neutrality and a sustainable energy economy. Component corrosion/ degradation remains a major threat to EESC device's long-term durability. Here, we provide a comprehensive account of the EESC device's corrosion and degradation issues. Discussions are mainly on polymer electrolyte membrane fuel cells, metal-ion and metal-air batteries and supercapacitors. Corrosion of bipolar plates/current collectors, carbon corrosion, electrode/ electrocatalyst degradation, and various mitigation approaches are detailed. The collective information provided could help develop EESC devices with better durability.

“…Coulomb efficiency can reflect the reversibility of supercapacitor electrode materials in the charging and discharging process, which can be calculated using Equation ( 13). [67,68] The graph relating specific current and respective Coulombic efficiency has been presented in Figure 5d. The Coulombic efficiencies of NiFe-LDH-6 h, NiFe-LDH-8 h, NiFe-LDH-12 h, NiFe-LDH-16 h, and NiFe-LDH-24 h were 84.07%, 84.40%, 89.78%, 90.28%, and 85.00% at current density 1 A g À1 .…”

NiFe‐layered double hydroxide (NiFe‐LDH) as electrode materials for supercapacitors are successfully prepared by green and one‐step hydrothermal method without template. The controllable structure–performance relation of NiFe‐LDH nanoflower clusters (NCs) for green energy storage is realized by regulating reaction time. The morphology evolution of NiFe‐LDH is elucidated. NiFe‐LDH‐24 h offers a unique NC structure and has specific capacitance of 635.8 F g−1 at 1 A g−1, which is larger than one of the reported pure NiFe‐LDHs so far. The improved electrochemical performance of NiFe‐LDH‐24 h NCs is due to its unique structure and synergistic effect between components that cause the larger specific surface area and more electroactive sites for Faradic reaction. The reaction kinetics reveals the electrochemical energy storage mechanism of the NiFe‐LDH‐24 h NCs. The energy storage is contributed by diffusion and surface capacitance. The electrochemical performance of NiFe‐LDH‐24 h NCs is further modified for the first time by doping F, and the specific capacitance of F‐doped NiFe‐LDH‐24 h NCs (1942 F g−1) is increased by 3 times higher than that of NiFe‐LDH‐24 h NCs. This work provides a more solid theoretical basis for green energy storage through morphology control and doping modification strategies.
