Special Issue Information

Electrochemical energy conversion and storage is attracting special attention due to the drawbacks and limitations of existing fossil fuel-based technologies. The development of electrochemical energy conversion and storage devices has three directions: the development of batteries, development of capacitors, and development of fuel cells. Batteries are finding wide application in portable devices including laptop computers, mobile phones and cameras. Supercapacitors have the ability to accept and deliver charge at much faster rate than batteries, for many charge/discharge cycles. Fuel cells provide efficient and clean continuous power generation for both stationary and portable devices. These three technologies show promise of overcoming climate change problems caused by the use of fossil fuels. However, issues related to the electrode efficiency, membrane costs, and electrolyte stability, still limit the widespread commercialisation of batteries, capacitors and fuel cells.

The choice of electrode materials, as well as the electrolyte composition, determines the crucial electrochemical device parameters, such as specific energy and power, cycle life and safety. Accordingly, it is essential to develop the existing and introduce new procedures for the synthesis of electrode materials in batteries, capacitors and fuel cells. The development of new, improved electrocatalytic materials for batteries, capacitors, and fuel cell electrode reactions is expected to have great impact on device performance and, consequently, their commercialisation.

This Special Issue is focused on the development of electrocatalytic material for energy storage and conversion devices, including, but not limited to, the following topics:

  • Theoretical screening of material properties for the tailoring of electrocatalysts;
  • Novel non-platinum cathode materials for low-temperature fuel cells;
  • Novel non-metal cathode materials for low-temperature fuel cells;
  • Novel anode materials for alcohol fuel cells;
  • Novel anode materials for direct borohydride and ammonia fuel cells;
  • Novel electrode materials for sodium-ion rechargeable batteries of high efficiency;
  • Novel materials for supercapacitors;
  • Novel supporting materials for metal electrocatalysts for energy conversion devices;
  • New trends in the synthesis procedures of materials for electrochemical energy conversion and storage devices;
  • Characterisation of materials for electrochemical energy conversion and storage devices;
  • Testing of novel electrode materials for lab-scale fuel cells;
  • Development of novel electrolytes and membranes for electrochemical energy conversion and storage devices.

Abstract
A series of Li(Ni1/3Mn1/3Co1/3)1−xMxO2 (M = Al, Mg, Zn, and Fe, x = 0.06) was prepared via sol-gel method assisted by ethylene diamine tetra acetic acid as a chelating agent. A [...] Read more.
A series of Li(Ni1/3Mn1/3Co1/3)1−xMxO2 (M = Al, Mg, Zn, and Fe, x = 0.06) was prepared via sol-gel method assisted by ethylene diamine tetra acetic acid as a chelating agent. A typical hexagonal α-NaFeO2 structure (R-3m space group) was observed for parent and doped samples as revealed by X-ray diffraction patterns. For all samples, hexagonally shaped nanoparticles were observed by scanning electron microscopy and transmission electron microscopy. The local structure was characterized by infrared, Raman, and Mössbauer spectroscopy and 7Li nuclear magnetic resonance (Li-NMR). Cyclic voltammetry and galvanostatic charge-discharge tests showed that Mg and Al doping improved the electrochemical performance of LiNi1/3Mn1/3Co1/3O2 in terms of specific capacities and cyclability. In addition, while Al doping increases the initial capacity, Mg doping is the best choice as it improves cyclability for reasons discussed in this work. Full article
