Recently, much effort has been devoted to accomplish thin, lightweight and flexible energy-storage devices for wearable electronics. Here, we demonstrate a novel kind of thin all-solid-state supercapacitor configuration with an extremely simple process using two slightly separated stacked nanosheets-like Mn3O4 electrodes well solidified in the H2SO4 polyvinyl alcohol gel electrolyte. This integrate device shows a high specific capacitance of 127 F g(-1) for the electrode materials with good power and energy density values. These flexible and all-solid-state Mn3O4 supercapacitors bring new design opportunities of device configuration for future energy-storage devices. Present investigation first time reported that Mn3O4 is one of the most promising materials for the fabrication of all solid state thin film supercapacitors (ASSTFSs). (C) 2012 Elsevier Ltd.
