CNT/GT was dispersed in the binder and deposited on the SS sheet substrate using the doctor blade method and drying at a certain temperature. CNT/GT (mass composition 1:1) was dispersed in the binder with a stirrer for 10 min. The XRD patterns of the CNT/GT and CNT/GT/ZnO-300 composites can be found in Figure 1 .

Figure 1(b) shows the XRD pattern of the CNT/GT/ZnO composite with ZnO coating temperature of 300°C. SEM images of surface morphology and cross section of (a) CNT/GT and (b) CNT/GT/ZnO-300 composites on SS sheet substrate. It can be attributed to the overlap between CNT/GT and 4 μm thick ZnO layers.

Thickness of the ZnO over CNT/GT increases leading to the formation of clusters that block the pores in the electrode [17]. However, there is a decrease in capacitance of the CNT/GT/ZnO-300 sample in the scan rate from 20 to 200 mV/s. Overall, the addition of ZnO increases the capacitance value which was the highest value achieved in CNT/GT/ZnO-300.

The relatively higher capacitance in the CNT/GT/ZnO-300 sample was caused by the effect of the small crystallite size of ZnO. The temperature of 300 °C is the best temperature for drying ZnO material on the surface of CNT/GT. The performance of CNT/GT/ZnO electrodes was found to be dependent on the drying temperature of the ZnO material.

SJR is a size-independent prestige indicator that ranks journals according to their 'average prestige per article'. SJR is a measure of journal scientific impact that takes into account both the number of citations a journal receives and the importance or reputation of the journals from which those citations come. It measures the scientific impact of the average journal article. expresses how central to the global This indicator counts the number of citations received by papers from a journal and divides them by the total number of papers published in that journal.

The graph shows the evolution of the average number of times that documents published in a journal in the past two, three and four years have been cited in the current year. Evolution of the total number of journal citations and self-citations received by a journal's published papers over the previous three years. Journal Self-citation is defined as the number of citations from a journal citing an article to articles published in the same journal.

Development of the number of total citations per document and external citations per document (ie, self-citations from journal removed) received by a journal's published documents during the previous three years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal's documents. International Collaboration stands for the articles produced by researchers from several countries.

The graph shows the proportion of a journal's documents signed by researchers from more than one country; it includes more than one country address. Not every article in a journal is considered primary research and therefore "citable". This graph shows the ratio of a journal's articles including substantial research (research articles, conference papers and reviews) in three year windows vs. Proportion of a journal's items, grouped over three-year windows, that were cited at least once vs.
