Low-cost and high-performance electrode materials based on BiCoO3 microspheres

摘要: Abstract Ternary metal oxides have great potential for chemical storage devices because of their outstanding synergistic effects as well rich redox reactions. However, there are limited reports 3D structure BiCoO 3 materials and relevant electrochemical properties. Meanwhile, the study is reasonably important underlying researches. In this work, we successfully developed a urchin-like material without using any template surfactant. For supercapacitor application, showed specific capacitance 152 F g −1 at current density 1 A g , value exhibited rate capability 82.3% high 10 A g . Furthermore, sample ideal cycling stability (92.7% retention after 5000 times cycles nearly invariable during different cycles). These results suggest that obtained has superb performances which its promising applications renewable clean energy electrode in future.
