Abstract
Correction for ‘The use of a single-crystal nickel-rich layered NCM cathode for excellent cycle performance of lithium-ion batteries’ by Qiankun Guo et al., New J. Chem., 2021, 45, 3652–3659; DOI: 10.1039/d0nj05914e.
The authors regret the following errors in the original manuscript.
(1) The original manuscript contained errors in Fig. 5b and 6a. Corrected versions of Fig. 5 and 6 are shown below.

(2) The corresponding text in the “Abstract” section has been corrected as follows.
Under the test conditions of 25 °C and 2.75–4.30 V, the first discharge specific capacity of a button cell at 0.1C (1C = 210 mA g−1) reaches 209.7 mA h g−1, the coulomb efficiency is 91.19%, and the capacity retention is 99.56% after 100 cycles at a rate of 0.2C.
(3) The corresponding text in the “Results and discussion” section has been corrected as follows.
Next, CR2032 button cells were used for cycle testing, and the specific discharge capacity of the SC-NCM cathode decays to 199.81 mA h g−1 after 100 cycles at 0.2C rate, and the capacity retention is 99.56%, which is better than that of the N-NCM cathode (187.78 mA h g−1 and 89.86%, respectively) (Fig. 5b).
These mistakes do not change the general scientific conclusion of the paper.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
