Abstract:
To develop the next-generation energy storage systems, lithium-sulfur batteries represent an attractive option due to its high theoretical capacity, and energy density. In this work, MoS 2 /rGO (reduced graphene oxide) was prepared by hydrothermal synthesis and sulfur added
by the melt diffusion method. The as-prepared MoS 2 /rGO has strong polysulfides entrapping, high conductivity, large surface area, and high catalytic activity, consequently resulting in enhanced rate performance and cycling capability of Li-S batteries. The coin cells were constructed
with the MoS 2 /rGO/S cathode material, exhibit a high reversible capacity of nearly 1380 mAh/g at 0.1 C, outstanding cycling stability with a low capacity fading rate. Present work reveals that the hierarchal MoS 2 /rGO/S cathodes are potential candidate materials for future
high-performance lithium-sulfur batteries.
