| Abstract: | NiO nanosphere for supercapacitors was prepared using different methods. The morphology and structure of samples were analyzed by X- ray diffraetion（XRD）, scanning electron microscopy（SEM） and transmission electron microscopy （TEM）. The results showed that the prepared samples with the ultrasound method in the presence of a surfactant （SDBS） were nanosphere and the average diameter of NiO nanospheres is only 1 - 3 nm. Within the potential range of - 0.4--0.6 V, NiO - US showed a typical quasi -Faraday capacitance characteristics. |
