Special Issue Information

Dear Colleagues,

Rapid urbanization and modernization have demanded an urgent need for renewable energy sources and resources. Energy storage is one of the ways to address these issues. Supercapacitors (electric double layer capacitors, pseudocapacitors) have emerged as potential devices that show high power density, rapid charge–discharge, and long cyclability. Various semiconducting nanostructures materials have been developed for high-performance electrode materials. The variety of surface modifications, surface active sites, and tuning surface chemical properties can be controlled via nanoengineering. The theoretical limits of electrode materials are being investigated, for example, through DFT. Electrode materials that show dual behavior, viz. supercapacitors and batteries, are of interest for researchers. Hybrid materials and the study of their electrochemical performance also represent a potential strategy.

The present Special Issue will cover original full-length research articles and review papers on high-performance supercapacitors and battery applications. Reviews may cover conceptual advances in supercapacitors and batteries, or could be more in the form of tutorials that address specific challenges in energy storage and approaches to overcoming them. Papers may focus on the development of energy storage devices for commercialization or the development of electrode materials that are used to provide new scientific knowledge.    

Potential topics include but are not limited to:

  • Chemical synthesis of electrode materials;
  • Direct growth of nanostructures;
  • Oxides, sulfides, and chalcogenides;
  • Carbon materials;
  • Conducting polymers;
  • Nanocomposites;
  • Electrochemical characteristics;
  • Device fabrications;
  • Supercapacitors and batteries;
  • DFT;
  • Hybrid materials.

Considering their high abundance in the earth, iron-based materials have occasionally been regarded as promising electrode materials for supercapacitors. However, monometallic iron-based electrodes still demonstrate an insufficient specific capacitance value in comparison to monometallic Mn-, Ni-, and Co-based compounds and their combined materials. Herein, an enhanced iron-based heterostructure of Fe3O4@Fe2P was prepared via the in situ phosphorization of Fe3O4. Compared to pristine Fe3O4, the Fe3O4@Fe2P heterostructure showed a capacity enhancement in KOH aqueous solution. The improved electrochemical performance can be attributed to both the core shell structure, which favors buffering the collapse of the electrode, and the synergistic effect between the two iron compounds, which may provide abundant interfaces and additional electrochemically active sites. Moreover, the assembled asymmetric supercapacitor device using the Fe3O4@Fe2P heterostructure as the positive electrode and activated carbon as the negative electrode delivers a high energy density of 13.47 Wh kg−1, a high power density of 424.98 W kg−1, and an acceptable capacitance retention of 78.5% after 5000 cycles. These results clarify that monometallic Fe based materials can deliver a potential practical application. In addition, the construction method for the heterostructure developed here, in which different anion species are combined, may represent a promising strategy for designing high-performance electrodes.
