ABSTRACT: Energy density and production cost for high-performance electrode materials are the main challenge for the capacitive storage technology. In this paper, novel Hydroxide Zinc Carbonate (Zn4CO3(OH)6·H2O, HZC) catalyst layers, which are composed of irregular stagger arrangement nanosheets, have been synthesized successfully on foam Ni from inorganic precursors by a feasible in situ hydrothermal method. Measured by electrochemical tests as electrode materials for supercapacitors, the HZC@Ni foam show high specific capacitance (1329.2 F·g−1 at 1 A·g−1 and 882.8 F·g−1 at 10 A·g−1, respectively). These results show that the HZC@Ni foam could be a potential electrode material for supercapacitors. These encouraging results make these low-cost and eco-friendly materials promising for energy storage application.
