This brief introduces the reader to the topic of superhalogens, a special class of atomic clusters that can potentially mimic the behavior of halogen atoms. It provides an introduction to the history of superhalogens, their conceptualization, and experimental confirmation and discusses in detail their properties and various applications. Some of the applications analyzed in the text include their potential use in the design of superacids, electrolytes for Li-ion batteries, and organic superconductors as well as their use in ionic liquids. The latest developments in the field are also presented. This brief is of great interest to graduates and researchers working at the interface of chemistry, physics, and materials science.
