英文摘要Tin sulfides have attracted great attention as promising anode materials for lithium-ion batteries due to their high theoretical specific capacity. However, the rapid capacity decay, resulting from the structural instability of tin-sulfide-based anodes over cycling, impedes its practical applications. Herein, the simple and controllable synthesis of one-dimensional (1D) SnS nanorods decorated in N-doped hierarchical porous carbon (N-HPC/SnS) through in situ phase transformation from N-HPC/SnS2 under thermal annealing is carried out. This structural design leads to fast ion/electron transport and enough space for volume variations. The resultant electrochemical test verifies the advantages of the as-developed materials, which exhibits great cycling stability with a high specific capacity of 638.74 mAh/g over 800 cycles at 0.5 A/g.
