Special Issue Information

Dear Colleagues,

Energy storage plays an important role in addressing the growing demand for sustainable and efficient energy systems. Electrochemical energy storage devices, such as batteries, supercapacitors, and fuel cells, have garnered significant attention due to their potential to store and deliver energy with high efficiency and reliability. The materials used for electrodes play a vital role in the performance of these devices. They determine important factors such as energy density, power density, and cycle life. Over the years, intensive research efforts have been directed towards advancing electrode materials and modifying them to enhance their energy storage performance. These advancements encompass a broad spectrum of strategies, including the development of novel materials with tailored properties, surface treatment/ modifications to improve their electrochemical kinetics, and the exploration of nanostructured architectures to optimize ion transport and charge storage mechanisms. Through novel designs and engineering at the electrode level, researchers have attempted to open up new pathways for next-generation energy storage technologies with improved performance, durability, and sustainability.

This Special Issue on “Advances in Electrode Materials for Energy Storage Applications” aims to present cutting-edge research in this field; thus, we seek high-quality pieces of work focusing on the latest advances being made to various electrode materials and their applications, as well as studies which aim to identify future priorities and directions, including the use of nanoparticles, nanoporous materials, nanocatalysts, nanocomposites within supercapacitor and batteries technologies. We cordially extend an invitation to submit your valuable and original articles or reviews to this Special Issue. Research areas may include, but are not limited to:

  • The Synthesis and characterization of novel nanostructured electrode materials;
  • The design and fabrication of hierarchical electrode architectures and nanocomposites;
  • The development of environmentally friendly electrode materials and manufacturing processes;
  • Surface engineering technology (e.g., surface coatings, functionalization, doping);
  • Energy storage mechanisms;
  • Ionic liquid and solid-state electrolytes studies;
  • Flexible and wearable energy storage;
  • The improvement of commercialized electrode materials.

Achieving high energy density while maintaining high power density and long cycle life in supercapacitors, particularly in supercapatteries (SCs), through a thermally stable, greener ionic liquid approach remains a significant challenge for an advanced energy storage application. In this work, we prepared high conductive and high charge storage capability bimetallic transition metal molybdate [Ag2Mo2O7 (AgM)], synergistic with reduced graphene oxide (rGO) coated on nickel foam (AgM/rGO/NF). The physio-chemical characterization revealed a ball-like cluster morphology wrapped in rGO nanosheets and a spinel-type cubic structure using scanning electron microscopy (FE-SEM) displays and X-ray diffraction (XRD) analyses. Further, the electrochemical performance of AgM/rGO/NF electrode achieved a remarkable specific Csp value of 573.63 F/g at a current density of 1.0 A/g in 3 M KOH electrolyte. An asymmetric SCs (ASCs) device was fabricated using AgM/rGO/NF as the positive and rGO as the negative electrodes, achieving a wide potential window of 1.3 V. The ASC demonstrated an energy density of 16.71 Wh/kg at a power density of 642.98 W/kg, highlighting AgM/rGO/NF’s potential as an advanced electrode material for energy storage applications.

Mn5(H2O)4(PO3OH)2(PO4)2 with an open 3D network was prepared and studied as electrode material for electrochemical capacitors. The material exhibits a tunnel structure along the c axis, characterized by a hydrogen bond network formed by water molecules bonded to MnO6 octahedra and PO3-OH tetrahedra units, the latter containing an acidic proton. Electrochemical studies were conducted on both alkaline and neutral electrolytes, revealing a profile indicative of a rapid faradaic process coupled with pseudocapacitance and electrochemical double-layer capacitance. This study proposes a mechanism that involves the interaction between the acidic proton in the tunnel structure and OH− ions from the electrolyte, which diffuse through the hydrogen bond network. The material achieved a maximum specific capacitance of 184 Fg−1 at a scan rate of 5 mVs−1, with an areal capacitance of 4600 µFcm−2 in 3M KOH. This demonstrates its potential as a high-performance electrode for energy storage applications. Full article
