Special Issue Information

Dear colleagues,

This Special Issue is focused on the trends and prospects of energy materials representing a class of materials used in a variety of ways. For example, high-energy materials could be used in the civilian sector for mining, construction, or spacecraft engineering, while in the military sector, they are applied for defense and security. Energy materials are also used for energy storage in batteries and supercapacitors, as well as for energy conversion through solar cells, fuel cells, thermoelectric devices, etc. These materials are important in solving current global challenges such as increased energy consumption and environmental pollution.

The aim of this Special Issue is to summarize the success of the fundamental science and applied research on materials used for the harvesting, conversion, storage, transmission, and utilization of energy. The issue will also include achievements in decreasing materials’ sensitivity, toxicity, instability, and proneness to decomposition or degradation over a short time. Further additions to this issue will include modern and advanced signal flare compositions, an understanding of the ignition mechanisms, and continuing development of advanced ignition methods. Moreover, techniques for the characterization of energy materials and their output as well as principles and effects of explosions will be discussed in this Special Issue. We aim to disseminate the most recent advances and perspectives related to the development of new approaches to designing and investigating advanced energy materials and their safe application. Topics of interest for publication include, but are not limited to, the following:

 

  • Novel theoretical approaches to evaluating properties of high-energy materials;
  • Synthesis of advanced energy materials;
  • Properties of advanced energy materials and methods for their improvement;
  • Maintenance of high-energy materials;
  • Novel methods for high-energy material recognition.

In this paper, we present our investigations into the detonation performance and stability variations caused by replacing the -CF3 or -OCF3 group with -SF5. The widely applied DFT B3LYP/cc-pVTZ approach was employed to evaluate the HOMO–LUMO gap, cohesive energy, chemical hardness, and electronegativity. Based on these parameters, we predict the changes in chemical and thermal stability resulting from the inclusion of -SF5 instead of -CF3 or -OCF3. Our results indicate that, in some cases, the density of fluorine-containing nitro compounds decreases due to the presence of the pentafluorosulfanyl group. Additionally, machine learning techniques were used to determine the detonation pressure and velocity of fluorine–sulfur-containing compounds. Our findings suggest that fluorine-containing nitro compounds exhibit better detonation performance and stability than fluorine–sulfur-containing ones. Overall, the pentafluorosulfanyl groups inclusion of aromatic polynitro compounds improved neither the stability nor the detonation properties such as -CF3 or -OCF3 groups. Full article

Waste lithium-ion batteries (LIBs), which usually contain dangerous organic electrolytes and transition metals, including nickel, cobalt, iron, and manganese, can hurt the environment and human health. Substantial advancements have been achieved in employing high-efficiency, economical, and environmentally sustainable techniques for the recycling of spent LIBs. Converting exhausted LIBs into efficient energy conversion catalysts straightforwardly is a good strategy for addressing metal resource constraints and clean energy concerns. This transforms waste cathodes, anodes, binders, and separators from depleted LIBs into electrocatalysts free of platinum group metals for the oxygen evolution reaction (OER) and the oxygen reduction reaction (ORR). The composite, including transition metal oxide, graphene oxide, and carbon mass, will be synthesized from spent LIBs, demonstrating enhanced electrocatalytic activity. Utilizing “waste-to-energy” methods for used LIBs as catalysts would provide substantial benefits in environmental preservation and the effective production of functional materials in metal–air batteries.

The need for energy storage and the rapid development of new electronic platforms have prompted intense research into small and secure energy storage devices, particularly supercapacitors (SCs). Layered double hydroxides (LDHs) are potential electrode materials for SCs because of their excellent physicochemical and electrical characteristics. They involve interlayer spacing, high oxidation states, simplicity of synthesis, and distinct morphologies. Despite their potential, several kinds of LDHs still face constraints, such as particle aggregation, moderate surface area, and high resistance, which limit their use in energy storage. To overcome these challenges and enhance the electrochemical performance of LDHs, they have used strategies such as anion intercalation, oxygen vacancy, heteroatom, surfactant, fluorine, and metal doping, which have been demonstrated as electrode materials for SCs. Therefore, this review discusses recent advances in different LDHs and studies comparing bare and modified LDH for three- and two-electrode systems, with an emphasis on their morphologies, surface areas, and electrical properties for SC applications. It was found that modified LDHs achieve enhanced electrochemical performance in comparison to their corresponding bare LDHs. Consequently, there are potential opportunities to modify the surface of the recently invented LDHs for electrochemical investigations, which could result in improving their performance. This review also presents future perspectives on LDH-based energy storage devices for supercapacitors. Full article
