Correction to: Nature Energy https://doi.org/10.1038/s41560-020-0575-z, published online 9 March 2020.

In the version of this Article originally published, in the sentence beginning “Furthermore, the Li transference number...”, “(\(t_{{\mathrm{Li}}^{\mathrm{ + }}}\) ≈ 0.5)” was incorrectly written as “(\(t_{{\mathrm{Li}}^{\mathrm{ + }}}t_{{\mathrm{Li}}{\mathrm{ + }}}\) ≈ 0.5)”. In addition, the labels in Fig. 1a were missing. These errors have now been corrected.
