Recent Advances and Future Perspectives of VS₄ and Its Nanostructure Composites for Supercapacitor Applications: A Review

VS 4, also known as patronite, is a widely studied nanostructured material due to its fascinating high theoretical capacity. VS 4 has been getting much attention in supercapacitor as well as battery applications due to its parallel one-dimensional chain-like structure with an interchain spacing of 5.83 Å, which helps to provide space for accommodating the insertion/extraction of ions. There have been a number of scientific reports published on VS 4 and VS 4 -based nanocomposites for energy storage applications recently. In this aspect, here we summarize the charge storage properties of VS 4 and its nanocomposites including rGO, CNTs, MXenes, metal chalcogenides, and other carbon-based composites for supercapacitor applications. Moreover, challenges and future perspectives of VS 4 -based electrode materials are included in the conclusion.
