Author Correction: High-performance freestanding supercapacitor electrode based on polypyrrole coated nickel cobalt sulfide nanostructures (Scientific Reports, (2022), 12, 1, (4628), 10.1038/s41598-022-08691-2)

Abstract

Correction to: Scientific Reports, published online 17 March 2022 The original published version of this article contained errors in Figure 2. Both panels showed the NiCo2S4@PPy nanomaterial and, in addition, Figure 2b partially overlapped with Figure 6i. The error happened during the assembly of the original Figure. The original Figure 2 and accompanying legend appear below. (Figure presented.) SEM images of NiCo2S4 (a) and NiCo2S4@PPy nanomaterial (b). The original article has been updated.
