MoS2 nanosheets grown on amorphous carbon nanotubes for enhanced sodium storage

Abstract

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.
