Advancing lithium–sulfur battery efficiency: utilizing a 2D/2D g-C₃N₄@MXene heterostructure to enhance sulfur evolution reactions and regulate polysulfides under lean electrolyte conditions

Abstract

Lithium–sulfur batteries (LSBs) show promise for achieving a high energy density of 500 Wh/kg, despite challenges such as poor cycle life and low energy efficiency due to sluggish redox kinetics...

Synergistic design of g-C3N4-supported CNTs: experimental and DFT insights for enhanced electrochemical performance in flexible Li–S batteries

“…15 Additionally, tin disulde (SnS 2 ) nanosheets were anchored onto nitrogen-doped hollow carbon with mesoporous shells, forming a bipolar dynamic host with a capacity of 947.4 mA h g −1 at 0.2C. 16 Among the various host matrices explored in the past few years, [17][18][19] graphitic carbon nitride (g-C 3 N 4 or g-CN), a semiconductor material with a 2D structure akin to graphene, exhibits promising potential for improving Li-S battery performance. 20 Recent studies highlight g-C 3 N 4 's catalytic activity, stability, cost-effectiveness, and environmental friendliness, making it an attractive additive for Li-S batteries.…”
