A New Graphene-Based Fiber-Shaped Supercapacitor with High Electrochemical Performance

摘要：

　　Graphene fiber-based supercapacitors have been a hot topic of research due to their excellent mechanical and elec-trical properties.However,pure graphene fibers(GFs)usually have a low specific capacitance due to its low specific surface area(SSA)and limited electroconductivity.Therefore,in this work we utilize highly conductive substances MXene and CNTs to enhance the electrochemical performance of graphene-based fibers,which not only improve the tensile strength and electro-conductivity of the fiber but also contribute additional pseudocapacitance.Compared to GF prepared in this work,the pre-pared MXene/CNTs/graphene composite fiber(MCGF)shows higher electroconductivity of 420.42 S.cm-1 and larger area specific capacitance(CA)of 130.50 mF.cm-2,which greatly enhances the prospect of graphene fiber electrodes for flexible energy storage electronics.
