Corrigendum: Aqueous Calcium‐Ion Battery Based on a Mesoporous Organic Anode and a Manganite Cathode with Long Cycling Performance

During preparation of the version of record of the above manuscript, Figure 3 was duplicated as Figure 6. The correct Figure 6 is as follows: Figure 6. Typical CV curves of individual electrodes and typical charge–discharge curves of the aqueous Ca-ion cell based on SBA-15@PPTCDI‖Ca2MnO4: a) CV curves of SBA-15@PPTCDI as the anode, Ca2MnO4 as the cathode, and the SBA-15@PPTCDI‖Ca2MnO4 full cell at a scan rate of 0.5 mV s−1. b) Typical charge–discharge curves of the aqueous Mg-ion cell based on SBA-15@PPTCDI as the anode, Ca2MnO4 as the cathode, and SBA-15@PPTCDI‖Ca2MnO4 as the full cell at a current density of 100 mA g−1, based on cathode/anode weight. c) Galvanostatic charge–discharge curves at several current densities between 0 and 1.80 V. d) Ragone plot of the SBA-15@PPTCDI‖Ca2MnO4 cell. e) Cycling and coulombic performance of an aqueous CIB. f) A comparison to other previously reported CIBs or nonaqueous battery systems. This correction has no influence on the scientific content. The editorial office apologizes for this oversight and for any inconvenience caused.
