One-step construction of ?-MnMoO4 microstructures with enhanced lithium storage properties

Due to the synergistic effects of multiple transitional metals, high theoretical specific capacity and good electrical conductivity, alpha-MnMoO4 exhibits superior performance and can be utilized as one prospective lithium-ion battery anode material. Herein, a new solvothermal reduction method was adopted for the synthesis and construction of alpha-MnMoO4 microstructures. Both dart-like and nanosheet-based flower-like alpha-MnMoO4 microstructures can be prepared by tuning the initial amount of molybdenum acetylacetone during the reaction process. The electrochemical measurements show that the dart-like alpha-MnMoO4 mi-crostructures and nanosheet-based flower-like alpha-MnMoO4 microstructures deliver the stable specific ca-pacities of 951.4 and 861.4 mA h g-1 at a current density of 0.5 A g-1 after 400 cycles. The excellent capacity, stable and sustainable cyclic performance are much superior to the reported alpha-MnMoO4 particles. The improved electrochemical performance proves that alpha-MnMoO4 microstructures can be served as one prospective anode of lithium-ion batteries.(c) 2023 Elsevier B.V. All rights reserved.
