Owing to the popularity of carbon-based supercapacitors, diamond has also been examined as a potential candidate with unique advantages such as a wide electrochemical potential window and stable capacitive behavior in both aqueous and non-aqueous electrolytes. Moreover, its chemical stability in harsh environments at extreme applied potential and current provides rare opportunities for designing new supercapacitors. Owing to the intrinsic low surface area of diamond, it is necessary to increase the electrochemically active surface area or to produce diamond based composites ensuring capacitance improvement for the practical applications. According to the literature reports, the nano-engineered diamond structures can achieve a specific capacitance as high as 10 mF cm-2 with a specific energy of 10-100 Wh kg-1 in aqueous electrolyte. The present manuscript reviews the recent advancements in this topic of research by highlighting the potentials and challenges of diamond-based supercapacitors. The special attention was paid to fabrication methods and electrochemical performance of particular materials in view of further application for supercapacitor construction.
