Special Issue Information

Dear Colleagues,

The quest for efficient and sustainable energy storage solutions has spurred significant research into the synthesis and application of energy storage materials. Synthesis methodologies for these materials span from conventional solid-state reactions to cutting-edge nanomaterial techniques; tailoring their composition, morphology, and structure is essential for optimizing their performance.

Transition metal oxides, sulfides, carbon-based materials, and organic materials are prominent classes of materials explored for energy storage applications. They exhibit desirable properties such as high specific capacity, excellent cycling stability, and rapid charge/discharge rates, making them indispensable for addressing energy storage challenges in diverse sectors, from portable electronics to grid-scale energy storage. Energy storage materials find applications in various devices, including batteries, supercapacitors, fuel cells, and hybrid energy systems. Furthermore, the development of novel synthesis strategies, advanced characterization techniques, and theoretical modeling approaches has facilitated the discovery and optimization of such materials with unprecedented performance metrics. Research efforts aimed at enhancing energy density, efficiency, and sustainability continue to drive innovation in the field.

The upcoming “Energy Storage Materials: Synthesis and Application” Special Issue aims to provide a thorough examination of the latest advancements in energy storage material synthesis and application. These developments hold promise for addressing rapidly escalating environmental concerns and meeting the surging global energy demand. Within the scope of this Special Issue, we will delve into innovative material designs, novel green and sustainable chemical synthesis and processing methods, and advanced material characterization techniques.

We invite you to submit a manuscript for this Special Issue; full papers, communications, and reviews are all warmly welcome.

Polymer-derived silicon oxycarbide (SiOC) ceramics have garnered significant attention as novel silicon-based anode materials. However, the low conductivity of SiOC ceramics is a limiting factor, reducing both their rate capability and cycling stability. Therefore, controlling the free carbon content and its degree of graphitization within SiOC is crucial for determining battery performance. In this study, we regulated the free carbon content using divinylbenzene (DVB) and controlled the graphitization of free carbon with the transition metal iron (Fe). Through a simple pyrolysis process, we synthesized SiOC ceramic materials (CF) and investigated the impact of Fe-induced changes in the carbon phase and the amorphous SiOC phase on the comprehensive electrochemical performance. The results demonstrated that increasing the DVB content in the SiOC precursor enhanced the free carbon content, while the addition of Fe promoted the graphitization of free carbon and induced the formation of carbon nanotubes (CNTs). The electrochemical performance results showed that the CF electrode material exhibited a high reversible capacity of approximately 1154.05 mAh g−1 at a low current density of 100 mA g−1 and maintained good rate capability and cycling stability after 1000 cycles at a high current density of 2000 mA g−1.

Multiform NiO nanowalls with a high specific surface area were constructed in situ on carbon foam (CF) to construct NiO@CF/OD composite phase change materials (CPCMs). The synthesis mechanism, microstructures, thermal management capability, and photothermal conversion of NiO@CF/OD CPCMs were systematically studied. Additionally, the collaborative enhancement effects of CF and multiform NiO nanowalls on the thermal properties of OD PCMs were also investigated. NiO@CF not only maintains the porous 3D network structure of CF, but also effectively prevents the aggregation of NiO nanosheets. The chemical structures of NiO@CF/OD CPCMs were analyzed using XRD and FTIR spectroscopy. When combined with CF and NiO nanosheets, OD has high compatibility with NiO@CF. The thermal conductivity of NiO@CF/OD-L CPCMs was 1.12 W/m·K, which is 366.7% higher than that of OD. The improvement in thermal conductivity of CPCMs was theoretically analyzed according to the Debye model. NiO@CF/OD-L CPCMs have a photothermal conversion efficiency up to 77.6%. This article provided a theoretical basis for the optimal design and performance prediction of thermal storage materials and systems. Full article

An electrochromic supercapacitor device (ESD) is an advanced energy storage device that combines the energy storage capability of a supercapacitor with the optical modulation properties of electrochromic materials. The electrode materials used to construct an ESD need to have both rich color variations and energy storage properties. Recent advances in ESDs have focused on the preparation of novel electrochromic supercapacitor electrode materials and improving their energy storage capacity, cycling stability, and electrochromic performance. In this review, the research significance and application value of ESDs are discussed. The device structure and working principle of electrochromic devices and supercapacitors are analyzed in detail. The research progress of inorganic materials, organic materials, and inorganic/organic nanocomposite materials used for the construction of ESDs is discussed. The advantages and disadvantages of various types of materials in ESD applications are summarized. The preparation and application of ESD electrode materials in recent years are reviewed in detail. Importantly, the challenges existing in the current research and recommendations for future perspectives are suggested. This review will provide a useful reference for researchers in the field of ESD electrode material preparation and application. Full article
