Layered Ca0.28MnO2·0.5H2O as a High Performance Cathode for Aqueous Zinc‐Ion Battery

Small 2020, 16, 2000597 In the originally published article, the valence states of Mn were mislabeled in Figure 5f and Figure S2, Supporting Information. The corrected panels and main text are presented below. The authors state that the errors do not affect the accuracy of the main conclusion and apologize for any misunderstanding this may have caused. The corresponding original text (page 2, right column): “As shown in Figure S2 in the Supporting Information, about 66.2% Mn4+ and 33.8% Mn3+ exist in as-prepared CaMnO.” Is updated to: “As shown in Figure S2 in the Supporting Information, about 33.8% Mn4+ and 66.2% Mn3+ exist in as-prepared CaMnO.”
