The authors regret errors in the list of co-authors, in the data and corresponding text for Fig. 1b and 5, and in the captions for Fig. 1–5.

Hongshuai Hou and Xiaobo Ji wish to be removed from the authorship of this paper. The experiments, data compilation and writing of this article were carried out by the first author Hongliang Li and the corresponding author Mingxiang Deng, and the article was submitted by Hongliang Li. And they erroneously listed Xiaobo Ji and Hongshuai Hou as co-authors. Xiaobo Ji and Hongshuai Hou only provided some instruments and consumables for the experiments in this paper, so Xiaobo Ji and Hongshuai Hou do not feel their contribution is sufficient to be authors on this paper, and they request to update the authorship of this article to remove Hongshuai Hou and Xiaobo Ji as authors of this paper. The correct authorship is presented herein.

The following sentence should be included in the acknowledgements: ‘The authors thank Hongshuai Hou and Xiaobo Ji for providing experimental equipment and resources.’

The authors regret that the images provided for Fig. 1b and 5 in the original article are incorrect. Corrected versions of Fig. 1b and 5 are provided herein.

Fig. 2 (a) Rate performance of the Sb₂S₃ electrode. (b) Nyquist plots of G/Sb₂S₃ and stibnite at the initial state. (c) Nyquist plots of G/Sb₂S₃ at different states. Reproduced in part from Mingxiang Deng et al., RSC Adv., 2019, 9, 15210–15216.¹

The corresponding text “Finally, the content of Sb₂S₃in the G/Sb₂S₃ composite was determined to be 66.68 wt%.” in the original article should be corrected as “Finally, the content of Sb₂S₃ in the G/Sb₂S₃ composite was determined to be 74.68 wt%.”

The corresponding text “The G/Sb₂S₃ composites delivered the average reversible capacities of 642.3, 507.6, 392.1 and 264.9 mA h g⁻¹” in the original article should be corrected as “The G/Sb₂S₃ composites delivered the average reversible capacities of 544.9, 497.6, 474.5 and 407.0 mA h g⁻¹”.

The corresponding text “the average reversible capacity of the G/Sb₂S₃ composites could recover to 595 mA h g⁻¹ after 20 cycles” in the original article should be corrected as “the average reversible capacity of the G/Sb₂S₃ composites could recover to 576.7 mA h g⁻¹ after 20 cycles”.

The corresponding text “After 75 cycles, the reversible capacity was 422 mA h g⁻¹ with the capacity retention of 82.9%.” in the original article should be corrected as “After 75 cycles, the reversible capacity was 365.0 mA h g⁻¹ with the capacity retention of 67%.”

The authors wish to draw the readers’ attention to their closely related RSC Advances¹ paper, published at nearly the same time, which should have been cited in this RSC Advances paper.
