MoSe2 nanoflowers grown on 3D carbon network as an advanced anode for lithium ion batteries

2D layered transition metal dichalcogenides deliver much higher specific capacity than the commercial graphite. However, they suffer from severe problems in practical applications such as low conductivity and poor cycling stability. Herein, we report a nanoflower-like MoSe2 grown on a 3D carbon network synthesized by efficient hydrothermal method. It shows a high specific capacity of 717.9 mAh/g in the initial cycle, with no capacity loss from the second to the fiftieth cycle. With the help of the 3D carbon network, MoSe2 nanoflowers present a stable structure with less agglomeration and then provide more active sites for the lithium storage, leading to better electrochemical performance. The present work suggests fabricating 3D hierarchical architectures applying simple synthetic methods could be an efficient strategy for designing advanced anode materials.
