Correction: High capacity potassium-ion battery anodes based on black phosphorus (Journal of Materials Chemistry A (2017) 5 (23506-23512) DOI: 10.1039/C7TA02483E)

The authors regret that the value of the theoretical capacity of phosphorus was incorrectly reported as 843 mA h g1 in the originally published version of the manuscript. The correct value should read 865 mA h g1. The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers..
