[Display omitted] •This article conveys the significance of black phosphorus (BP) in the application of electrochemical supercapacitors.•The properties and synthesis methods of BP are reviewed and explained.•Current shortcomings and the scope for improvement of BP have been concisely discussed. Black phosphorus (BP) has emerged to be a promising material in various fields like material science, condensed matter physics, chemistry, etc. Bearing the properties like narrow and direct band gaps, remarkable flexibility, high conductivity, electron mobility, and theoretical capacity, along with an anisotropic structure opens doors for BP in the field of energy storage devices. Also, the spacing between the layers of BP is 0.55 nm which has proved to be higher than graphene which supports better ion transportation in the case of supercapacitors (SCs). In this article, we briefly discuss many BP-based electrodes which were synthesized using the top-down and bottom-up approaches, the properties possessed by the material, and their application in SCs. The review also examines the strategies which can amplify the electrochemical performances proving to help fabricate the supercapacitor electrodes and devices. The potential of BP in constructing low-cost, flexible, and high-performing materials for SCs is also discussed. The review finally states the current shortcomings in the available literature and the direction of research which can provide a stage for never-ending improvements in this subject.
