Correction for ‘Biomass-derived hierarchical porous carbons: boosting the energy density of DOI: 10.1039/c7ta90265d supercapacitors via an ionothermal approach’ by Yuchuan Liu et al., J. Mater. Chem. A, 2017, 5, 13009– www.rsc.org/MaterialsA 13018.

The authors regret a mistake in reporting the testing conditions of the two-electrode system of supercapacitors. On page 13011, le column, line 2, the sentence “Specically, it was composed of a glassy brous separator and our samples in 6 M KOH solution.” should read “Specically, it was composed of a glassy brous separator and our samples in 6 M KOH solution ¼  ¼ ” Creative Commons Attribution 3.0 Unported Licence. or 1 M Et4NBF4/PC electrolyte (Et4NBF4 tetraethylammonium tetra uoroborate; PC propylene carbonate). On page 13016, right column, line 9, the sentence “To evaluate its application as electrodes, a supercapacitor based on the as- prepared ITC-JG-900 was assembled” should read “To evaluate its application as electrodes, a supercapacitor based on the as-

prepared ITC-JG-900 was assembled in 1 M Et4NBF4/PC electrolyte”. On page 13017, le column, line 8, the sentence “this value still remains at 38.8 W h kg 1 at a high power density of 12 500 W h kg 1 in 6 M KOH” should read “this value still remains at 38.8 W h kg 1 at a high power density of 12 500 W h kg 1 in

1MEt4NBF4/PC electrolyte”. The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers. This article is licensed under a Open Access Article. Published on 22 November 2017. Downloaded 9/25/2021 2:24:06 PM.
