? 2022 Elsevier B.V.In this study, binary transition metal oxide Mn2V2O7 nanoplates and nanosheet-based hierarchical microstructures were prepared by changing the V/Mn molar ratio in the initial reactants using the solvothermal method. As the anode materials for lithium-ion batteries, the electrochemical properties of both Mn2V2O7 are investigated. After 300 cycles, a discharge capacity of 1014.3 mA h g?1 for Mn2V2O7 nanoplates and 1096.0 mA h g?1 for Mn2V2O7 nanosheet-based hierarchical microstructures can be maintained at the current density of 0.5 A g?1. The nano-sheets structures shorten the transmission paths of ions and electrons, while the synergistic effect occurred between manganese and vanadium elements also enhance the electrochemical activity. Therefore, the manganese vanadium oxide materials prepared in this study exhibit great prospects for application in energy storage devices.
