Nanostructured Co 3 O 4 was prepared via a simple two-step process: cathodic electrodeposition of cobalt hydroxide from additive free nitrate bath and then heat treatment at 400°C for 3 h. The prepared oxide product was characterized by powder X-ray diffraction, infrared spectroscopy, surface area measurement, scanning electron microscopy, and transmission electron microscopy. Morphological characterization showed that the oxide product was composed of porous nanoplates, and BET measurement displayed that the oxide plates have the average pore diameter and the surface area of 4.75 nm and 208.5 m 2 g -1 , respectively. The supercapacitive performance of the nanoplates was evaluated using cyclic voltammetry and charge-discharge tests. A specific capacitance as high as 393.6 F g -1 at the constant current density of 1 A g -1 and an excellent capacity retention (96.5% after 500 charge-discharge cycles) was obtained. These results indicate that Co 3 O 4 nanoplates can be recognized as high-performance electrode materials.

“…In addition, after conforming to complex nonplanar surfaces in these deformation tests, the supercapacitors can recover to their original shapes without permanent deformation preserved, revealing an excellent structure-performance reliability. Table 1 compares performances of various PPy-based solidstate supercapacitors with our devices [54][55][56][57][58][59][60][61][62][63]. It is clear that our stretchable PPy supercapacitors possess outstanding performances, including excellent cycling stability, high rate capability, decent capacitance and great flexibility.…”
