MoS2 nanosheets grown on amorphous carbon nanotubes for enhanced sodium storage

In this work, we demonstrate a step-wise route to build a novel one-dimensional (1D) architecture formed by MoS2 nanosheets and amorphous carbon nanotubes (ACNTs). Being evaluated as an anode material for NIBs, the as-prepared MoS2@ACNT electrode is capable of exhibiting a remarkable reversible capacity of 461 mA h g(-1) at a current density of 500 mA g(-1) over 150 cycles. Moreover, the coulombic efficiency is almost up to 100% except for the initial few cycles during the whole cycling test. The smart electrode architecture and appropriate synergistic effect between MoS2 and ACNTs are probably responsible for the enhanced electrochemical performance.
