摘要
Summary of main observation and conclusion Carbon based composite materials have gained much attention because of fulfilling desirable properties for supercapacitor application.In the featured work,the thin film of Bi2S3∶PbS solid solution has been synthesized on multi-walled carbon nanotubes(MWCNTs)by simple successive ionic layer adsorption and reaction(SILAR)method.The nanoparticle morphology provides sufficient electroactive channels for electrolyte ions to penetrate during electrochemical activities.The composite exhibits superior specific capacitance 676 F/g at constant specific current density of 5.56 A/g with fast charge-discharge cycles.In association of energy storage characteristics,the fabricated symmetric cell exhibits excellent energy density of 13.36 Wh/kg by acquiring power density of 0.83 kW/kg.The superior results of the hybrid electrode promise a novel direction for high performance supercapacitor application.
