dc.description.abstract | Hydrous forms of cobalt molybdate binary metal oxide nanoaggregates were synthesized via a simple chemical co-precipitation technique. The subsequent heat treatment at 400 degrees C converted the sample into anhydrous cobalt molybdate (CoMoO4) with mesoporous nanostructure. The anhydrous cobalt molybdate possess surface area and pore volume of 63.92 m(2)g(-1) and 0.1802 cm(3)g(-1) which is much higher than the hydrous cobalt molybdate (1.215 m(2)g(-1) and 0.0072 cm(3)g(-1)). The electrodes designed using these materials exhibited a battery-like behavior with maximum specific capacity of 97 Cg(-1) and 177 Cg(-1) for hydrous and anhydrous cobalt molybdate samples respectively. In addition, a supercapattery was fabricated utilizing anhydrous cobalt molybdate//activated carbon electrodes, which showed maximum specific capacity value of 64 Cg(-1) at 1 Ag-1 discharge specific current and showed better specific energy similar to 18.89 Whkg(-1) for a specific power of 1.06 kWkg(-1). Moreover, the supercapattery exhibited good capacity retention similar to 93% after 5000 charge/discharge cycles. | - |
