Abstract

A layered calcium vanadium oxide bronze (Ca0.25V2O5⋅nH2O, CVO) has been synthesized to act as the cathode for aqueous zinc‐ion battery applications. H. N. Alshareef and co‐workers describe in their Communication (DOI: 10.1002/anie.201713291) how the Zn atoms from the anode (silver spheres) move to the CVO cathode during the discharge process to generate energy (shown by the lit lamp). The background shows the Zn element flying out of the periodic table to signify the high capacity reached.
