摘要
Abstract Two-dimensional transition metal dichalcogenides (TMDs) are regarded as the ideal hosts for zinc-ions. Herein, a facile hydrothermal method is proposed to fabricate the metallic phase (1T phase) MoS 2 /multi-walled carbon nanotube (MWCNT) hybrids serving as the cathode materials for zinc-ion batteries (ZIBs). By virtue of the exertion of phase engineering and the synergistic between the 1T MoS 2 nanosheets and MWCNT framework, the transfer kinetics of zinc-ions of the prepared hybrid is remarkably accelerated, leading to the boosted electrochemical properties at both room temperature and low temperatures. The hybrid electrode delivers a high reversible capacity of 161.5 mAh g -1 after 100 cycles at 0.1 A g -1 , and good cycling stability with a desired capacity retention of 84.6 % over 500 cycles at 1 A g -1 . Furthermore, its boosted capability of zinc-ion storage in low-temperature atmosphere is revealed. This work not only provides an effective way to squeeze the values of phase engineering of MoS 2 in ZIBs, but also reveals the great potential of MoS 2 -based composites in low-temperature energy storage devices.
