Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The development and advantages of wearable flexible electronics have become attractive issues with excellent electrochemical performances in energy storage devices. In this study, we highlighted a low cost and green fabrication of bio-supercapacitor using poly(vinyl alcohol) (PVA):Nano-eggshell microcomposites. As it is known, interest in the production of green supercapacitors is increasing rapidly. A uniform PVA:Nano-eggshell microcomposite morphology was obtained in the polymer blend-based nanostructure using kappa-carrageenan as the matrix. PVA:Nano-eggshell microcomposites were prepared and coated on a Ni foam. The performance of PVA:Nano-eggshell microcomposites-Ni foam-based supercapacitor was investigated. Kappa-carrageenan was used to increase the specific capacity due to the large number of free charges. The proposed supercapacitor showed a high specific capacitance of 255 F/g in [0, 1] V range at 100 mV/s scan rate. These results demonstrated that the proposed electrode of PVA:Nano-eggshell microcomposites is to be a promising high performance and flexible supercapacitor in energy storage applications.
