NH_4V_4O_(10) micro-flowers as cathode material for high performance hybrid magnesium-lithium-ion batteries

摘要

The hybrid magnesium-lithium-ion batteries (MLIBs) combine the advantages of Mg anode and the Li+ intercalation cathode. Constructing high-performance cathode is the key and challenge for the futuristic MLIBs research. Layer NH4V4O10 is found to be an ideal cathode for MLIBs owing to layer structure and high work voltage (similar to 1.8 V vs. Mg/Mg2+). In this work, the NH4V4O10 micro-flowers are prepared through a facile hydrothermal method. As cathode for MLIBs, the NH4V4O10 exhibits a high specific discharge capacity of 228 mAh g (1) at 100 mA g (1) in the voltage range of 0.5-2.0 V vs. Mg/Mg2+. (C) 2019 Elsevier B.V.
