Along with the great success of traditional lithium-ion batteries, the increasing energy demand has been promoting the rapid development of novel battery systems for even large energy density and high power density, and good safety. Typically, novel types of rechargeable batteries based on redox reactions of halogens have attracted extensive attention because of the potential fundamental chemistry and promising applications. In this frontier, we give an overview of halogen chemistry in rechargeable batteries, and the key ideas for various halogen-based batteries are discussed with particular analysis on the underlying mechanisms. Finally, the existing issues and future perspectives are also addressed for the development of halogen-based battery systems.
