Author Correction: Electrochemical Performance of Supercapacitor with Stacked Copper Foils Coated with Graphene Nanoplatelets

Correction to: Scientific Reports 10.1038/s41598-018-21572-x, published online 15 February 2018

This Article contains a typographical error in the Results and Discussion section where,

“This value is 213 times higher compared to graphitic powder (2.78 m²/g) 6, indicating that graphite was significantly exfoliated into few graphitic layers (2630/591 ≈ 4) by thermal exfoliation.”

should read:

“This value is 213 times higher compared to graphitic powder (2.78 m²/g)⁶, indicating that graphite was significantly exfoliated into few graphitic layers (2630/591 ≈ 4) by thermal exfoliation.”

In addition, this Article contains an error in the order of the Figures. Figures 2 and 3 were published as Figures 3 and 2 respectively. The correct Figures 2 and 3 appear below as Figures 1 and 2 respectively.
