The Effect of Heat Treatment after Hydrothermal Reaction on the Lithium Storage Performance of a MoS 2 /Carbon Cloth Composite.
Materials (Basel, Switzerland)(2023)
Abstract
In this study, 1T phase MoS nanosheets were synthesized on the surface of a carbon cloth via a hydrothermal reaction. After heat treatment, the 1T phase MoS was transformed into the 2H phase with a better capacity retention performance. As an anode material for lithium-ion batteries, 2H phase MoS on the carbon cloth surface delivers a capacity of 1075 mAh g at a current density of 0.1 A g after 50 cycles; while the capacity of the 1T phase MoS on the surface of the carbon cloth without heat treatment fades to 528 mAh g. The good conductivity of a carbon cloth substrate and the separated MoS nanosheets help to increase the capacity of MoS and decrease its charge transfer resistance and promote the diffusion of lithium ions in the electrode.
