ZnMn2O4@Mo6S9.5 hierarchical mesoporous microflowers have been constructed for anode applications in Li-ion batteries. The initial discharge/charge capacities of the microflowers were 1203/846 mA h g(-1), and the reversible capacity after high-current cycles remained high.
ZnMn2O4@Mo6S9.5 hierarchical mesoporous microflowers have been constructed for anode applications in Li-ion batteries (LIBs). Ultrathin Mo6S9.5 nanosheets have grown on ZnMn2O4 microspheres by hydrothermal method and calcination process to synthesis ZnMn2O4@Mo6S9.5 hierarchical mesoporous microflowers (HMMs). The initial discharge/charge capacities of ZnMn2O4@Mo6S9.5 HMMs were 1203/846 mA h g(-1). After high-current cycles, reversible capacity was 731 mA h g(-1) at 100 mA g(-1), which was close to that of the first 10 turns. The excellent performance could be ascribed to the synergistic effect among ZnMn2O4, Mo6S9.5 and the 3D hierarchical architecture. The results demonstrate that ZnMn2O4@Mo6S9.5 HMMs have broad application prospect as electrochemical energy storage device.
