Abstract

A facile water bath method was developed to synthesize layered iron vanadate Fe5V15O39(OH)9·9H2O (FVO) nanosheets. As a cathode material FVO delivers a high capacity of 385 mA h g−1 at 0.1 A g−1 due to the high proportion of variable valence elements (Fe and V). A remarkable cycling performance at a high current density is achieved in a Zn(TFSI)2 electrolyte.
