Supercapacitors (SCs) have drawn vast attention from academic and industrialized energy storage societies in the past few years because of their distinctive properties, such as outstanding cycling life, safe operation, ease of processing, and high power density compared to batteries. Nevertheless, the significant manufacture of SCs has been limited due to their comparatively low energy density. In this regard, the energy storage field has witnessed dramatic growth in the research efforts that aim to accomplish. In this regard, the captivating advantages of rich abundance and low-cost transition metals oxides and sulfides play an important role in the progress of electrode materials for SCs along with their energy-related performance. Here, I will present some recent developments in the rational and compositional design of some types of transition metal oxides and sulfides with controllable architectures, and their electrochemical performance as electrode materials for SCs will be highlighted.
