Novel Bimetal Oxides/Sulfides Composites Electrodes for Electrochemical Supercapacitors

Novel Bimetal Oxides/Sulfides Composites Electrodes for Electrochemical Supercapacitors

Shuhua Liu, Zongyu Huang and Xiang Qi

Supercapacitors (SCs) possess a bright future because of their high power supply and superior stability. Pseudocapacitive oxides of transition metals (NiCo2O4, FeCo2O4, Zn2SnO4 etc.) have been widely investigated for SCs ascribed to their high theoretical capacitances (>1000 F/g), environmental benignity, and low cost. In Bimetal sulfides (BMSs) such as MCo2S4 (M = Ni, Fe, and Cu) the efficient synergistic effect between two different metal ions makes them have more abundant oxidation reducing states, and their conductivity is qualitatively improved (four-order magnitude). This paper is hoped to provide a scientific basis to investigate the SCs technology.
