Abstract: The growing need to transform the society, which is currently driven, mainly by fossil fuels, with the consequent threats to climatic changes to one that is entirely fueled by clean energy that is renewable and sustainable, has attracted the attention of the academia and the industries. A broad spectrum of renewable energy sources has been identified in order to make energy, entirely available to society. Among these sources, are solar, wind, hydropower generation, tribological, geothermal and biomass. However, energy generation, storage and transmission remain cost-ineffective, inadequate and inefficient. With the vast amount of energy available to humanity, scientists and engineers are continually researching on new materials and innovative technologies that can power, store, and produce energy and always make it available to humans on demand. One of such wonder materials that holds enormous potential in energy storage is borophene. Borophene- a boron allotrope, is a two-dimensional nanostructure of an atom thickness. It has high thermal conductivity, higher mechanical strength than graphene, it is flexible and superconducting. It has enormous potential in energy storage systems due to its anisotropic nature, particularly in a battery-based energy storage system (BESS). It can also be used as an electrode material for supercapacitor. This review discusses the experimental synthesis of borophene. Special attention is given to its predictive and experimental properties. Finally, its nascent application as a potential storage material for: electrochemical, electrostatic, optoelectronic and thermoelectric systems are highlighted.
