Abstract | Square block-like sigma-Mg0.25V2O5 center dot H2O with an open layered framework has been successfully synthesized via a facile hydrothermal method. The entire synthetic process is efficient and economically beneficial. As a cathode material for lithium-ion batteries, the hydrated magnesium vanadium bronze exhibits a high reversible capacity and excellent cycling stability at high current rates. High discharge capacities of 294.2 and 221 mA h g(-1) can be obtained at the current densities of 20 and 100 mA g(-1), respectively. Meanwhile, the electrode achieves a capacity retention of 87.12% after 100 cycles at 100 mA g(-1) and has an excellent long-term cyclic stability with an average decay of 0.053% per cycle over 400 cycles at 800 mA g(-1). The structural stability and impedance variation of the sigma-Mg0.25V2O5 center dot H2O electrodes upon cycling have also been investigated. The excellent electrochemical performance suggests that the layered Mg0.25V2O5 center dot H2O could be a promising candidate for the cathode material of lithium-ion batteries. (C) 2018 Elsevier B.V.
