ZnMn2O4@Mo6S9.5 hierarchical mesoporous microflowers for Li-ion batteries

ZnMn 2 O 4 @Mo 6 S 9.5 hierarchical mesoporous microflowers have been constructed for anode applications in Li-ion batteries (LIBs). Ultrathin Mo 6 S 9.5 nanosheets have grown on ZnMn 2 O 4 microspheres by hydrothermal method and calcination process to synthesis ZnMn 2 O 4 @Mo 6 S 9.5 hierarchical mesoporous microflowers (HMMs). The initial discharge/charge capacities of ZnMn 2 O 4 @Mo 6 S 9.5 HMMs were 1203/846 mAh 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 ZnMn 2 O 4, Mo 6 S 9.5 and the 3D hierarchical architecture. The results demonstrate that ZnMn 2 O 4 @Mo 6 S 9.5 HMMs have broad application prospect as electrochemical energy storage device. • ZnMn 2 O 4 @Mo 6 S 9.5 HMMs synthesized by a hydrothermal reaction and annealing process. • ZnMn 2 O 4 @Mo 6 S 9.5 HMMs with excellent cycle properties. • The synergistic effect of Mo 6 S 9.5 and ZnMn 2 O 4 can reduce the diffusion length for electron and Li + ion transfer.
