Supercapacitors (SCs) can bridge the gap between batteries and conventional capacitors, playing a critical role as an efficient electrochemical storage device in the intermittent renewable energy sources. Transition metal-based electrode materials have been investigated extensively as a class of electrode materials for SCs application, where they have limitations due to the sluggish ion/electron diffusion and inferior electronic conductivity, restricting electrochemical performances towards energy storage. Developing the advanced transition metal-based electrode materials has been being crucial for high energy density along with high specific power and fast charging/discharging rates towards high performance SCs. In this review, we highlighted the state-of the art of transition metal-based electrode materials (transition metal oxides, and it composites, transition metal sulfides and its composites, and transition metal phosphides and their composites), focusing on specific morphologies, components and power characteristics. We also provide prospects guide for the transition metal-based electrode materials for SCs and hope this review will shed light on the achievement of higher performance and hold great promise in vast applications for future energy storage and conversion.
