Special Issue Information

Dear Colleagues,

The Special Issue, “Hybrid Graphene Materials for Energy Applications”, will address advances in materials synthesis, processing, characterization, and application into energy storage and conversion applications. Recent energy technologies have transformed the way we communicate and work without releasing any pollutant. Additionally, advances in these systems have developed carbon-free vehicles and large-scale renewable energy systems. To develop better energy systems, basic material design is the most important task. Therefore, in this Special Issue, we will focus on hybrid graphene materials for different energy applications, including batteries, supercapacitors, fuel cells, solar cells, thermoelectric generators, electro-catalytic conversions, etc. Using graphene’s marvelous properties, such as high electrical/thermal conductivity, high surface area, and catalytic properties, many researchers have developed functional hybrid materials and improved performance in different applications. Of particular interest are recent developments in graphene-based advanced materials, characterizations, and applications in energy-related systems. Articles and reviews dealing with these topics are very welcome.

Synthesis of Sodium Cobalt Fluoride/Reduced Graphene Oxide (NaCoF₃/rGO) Nanocomposites and Investigation of Their Electrochemical Properties as Cathodes for Li-Ion Batteries

Abstract

In this study, sodium cobalt fluoride (NaCoF₃)/reduced graphene oxide (NCF/rGO) nanocomposites were fabricated through a simple one-pot solvothermal process and their electrochemical performance as cathodes for Li-ion batteries (LIBs) was investigated. The NCF nanoclusters (NCs) on the composites (300–500 nm in size) were formed by the assembly of primary nanoparticles (~20 nm), which were then incorporated on the surface of rGO. This morphology provided NCF NCs with a large surface area for efficient ion diffusion and also allowed for close contact with the conductive matrix to promote rapid electron transfer. As a cathode for LIBs, the NCF/rGO electrode achieved a high reversible capacity of 465 mAh·g⁻¹ at 20 mA·g⁻¹ via the conversion reaction, and this enhancement represented more than five times the reversible capacity of the bare NCF electrode. Additionally, the NCF/rGO electrode exhibited both better specific capacity and cyclability within the current density testing range (from 20 to 200 mA·g⁻¹), compared with those of the bare NCF electrode.

Graphene-Based Two-Dimensional Mesoporous Materials: Synthesis and Electrochemical Energy Storage Applications

by Jongyoon Park, Jiyun Lee, Seongseop Kim and Jongkook Hwang

Abstract

Graphene (G)-based two dimensional (2D) mesoporous materials combine the advantages of G, ultrathin 2D morphology, and mesoporous structures, greatly contributing to the improvement of power and energy densities of energy storage devices. Despite considerable research progress made in the past decade, a complete overview of G-based 2D mesoporous materials has not yet been provided. In this review, we summarize the synthesis strategies for G-based 2D mesoporous materials and their applications in supercapacitors (SCs) and lithium-ion batteries (LIBs). The general aspect of synthesis procedures and underlying mechanisms are discussed in detail. The structural and compositional advantages of G-based 2D mesoporous materials as electrodes for SCs and LIBs are highlighted. We provide our perspective on the opportunities and challenges for development of G-based 2D mesoporous materials. Therefore, we believe that this review will offer fruitful guidance for fabricating G-based 2D mesoporous materials as well as the other types of 2D heterostructures for electrochemical energy storage applications.
