摘　　要：Lithium-sulfur(Li-S)batteries are regarded as one of the most promising candidates for next-generation high-energy-density storage systems due to their superior energy density,cost-effectiveness,and environmental friendliness.However,several critical challenges impede their practical application,including the shuttle effect,low conductivity,and volume expansion.Graphitic carbon nitride(g-C_(3)N_(4)),with its unique structure and properties,offers potential advantages in catalysis,polarization inhibition,electron conductivity,and sulfurization resistance,which may address these issues.This review concentrates on applying g-C_(3)N_(4) material to enhance Li-S battery performance.The research progress on g-C_(3)N_(4) in this context is explored from two primary perspectives:the modification of g-C_(3)N_(4) itself and its compounding with other materials.Regarding the modification of g-C_(3)N_(4),the focus is on defect engineering and the nanocrystallization of its structure.In terms of composites,the review examines the use of g-C_(3)N_(4) doped with metals,non-metals,graphene,porous carbon,and heterojunctions in electrodes and electrolytes.Ultimately,this review proposes strategies for the rational design of g-C_(3)N_(4) materials to optimize their application in Li-S batteries.Reviewing the current research progress and trends aims to provide new insights and directions for future research in the field.
