Supercapacitors store electrical energy by ion adsorption at the electrode‐electrolyte interface or in a Faradaic process involving the direct transfer of electrons via oxidation/reduction reactions at one electrode to the other (pseudocapacitance). Herein, recent advances in carbon‐transition metal oxide (C‐TMO) hybrid materials that show great promise as an efficient electrode towards supercapacitors among various material types are summarized. Synthetic methods and electrode preparation techniques along with the changes in the physical and chemical properties of each component in the hybrid materials are described.
