About this Research Topic
The development of renewable, safe, clean, and sustainable energy storage and conversion technologies has become a hot topic. A variety of technologies such as solar cells, fuel cells, supercapacitors, and batteries have been proposed to address future energy issues. Energy storage devices are essential for storing energy produced by renewable energy resources, for instance in electric vehicles or for their integration into the power grid and wind or solar power plants for continuous power supply. However, commercialization of these energy storage technologies on large scale is still hindered owing to the lack of availability of suitable electrode materials. Metal chalcogenides have emerged as a potential candidate for anode materials because of their versatile material species, ample abundance, low cost, robust nature and high theoretical capacities.
Several recent studies have reported that the binary metal chalcogenides exhibit better electrochemical performance than mono metal chalcogenides. However, further research is needed to reveal the understanding of the mechanisms behind this improved performance. Only a few combinations of the binary metal chalcogenides have been studied by now but there could be hundreds of other combinations possible. Hence, with an aim of achieving extraordinary anode material candidate, scientists are encouraged to explore other binary metal chalcogenide combinations. Furthermore, a major focus has been given to sulfur-based metal chalcogenides and very few studies reported Se based metal chalcogenides and several Se-based anodes have shown outstanding performances. Therefore, there is a need to focus studies on Se-based metal chalcogenides.
The Topic Editors welcome submissions of Original Research, Review, Mini Review and Perspective articles that address, but are not limited to, the following themes:
