Metal Oxides/Hydroxides Composite Electrodes for Supercapacitors

Rajendran Ramachandran, Murugan Saranya, Fei Wang

Supercapacitors (Electrochemical capacitors) are promising energy storage devices and have attracted significant attention as ‘bridges’ for the energy/power gap between traditional capacitors and batteries. The performance of supercapacitors is essentially determined by its electrode material. Among various supercapacitor electrodes, transition metal oxides/hydroxides usually exhibit high specific capacitance and energy densities. This chapter discusses the advantages and disadvantages of the supercapacitor and the supercapacitor performance of various metal oxide/hydroxides. Also, this review focus on the development and challenges of metal oxide/hydroxide based electrode materials.
