Abstract
Lithium sulfur batteries (Li-S) have been deemed to be the promising energy-storage systems. Nevertheless, the shuttle effect caused by diffusion of polysulfides limit their application. In this work, the different dimensions of g-C₃N₄ nanomaterials (2D g-C₃N₄ nanosheets and 3D g-C₃N₄ nanomesh) were doped in S electrode. Because of the large specific surface area of 3D g-C₃N₄ nanomesh and strong chemical adsorption of polysulfides can provide better effect for inhibition of shuttling effect and its proper electron passage make electrochemical kinetics of lithium-sulfur battery enhanced. The discharge specific capacity of the 3D g-C₃N₄ battery is up to 731 mAh/g and longer cycling performance with 540 mAh/g after 180 cycles. This experiment paves the way forward for the application of g-C₃N₄ on Li-S batteries.
