Manganese doping to boost the capacitance performance of hierarchical CO9Sg@Co(OH)2 nanosheet arrays
文献摘要：
Transition metal sulfides(TMSs)have been regarded as greatly promising electrode materials for supercapacitors because of abundant redox electroactive sites and outstanding conductivity.Herein,we report a self-supported hierarchical Mn doped Co9S8@Co(OH)2 nanosheet arrays on nickel foam(NF)substrate by a one-step metal-organic-framework(MOF)engaged approach and a subsequent sulfurization process.Exper-imental results reveal that the introduction of manganese endows improved electric conductivity,enlarged electrochemical specific surface area,adjusted electronic structure of CogSg@Co(OH)2 and enhanced interfacial activities as well as facilitated reaction kinetics of electrodes.The optimal Mn doped Co9S8@Co(OH)2 electrode exhibits an ultrahigh specific capacitance of 3745 F g-1 at 1 A g-1(5.618 F cm-2 at 1.5 mA cm-2)and sustains 1710 F g-1 at 30 A g-1(2.565 F cm-2 at 45 mA cm-2),surpassing most reported values on TMSs.Moreover,a battery-type asymmetric supercapacitor(ASC)device is constructed,which delivers high energy density of 50.2 Wh kg-1 at power density of 800 W kg-1,and outstanding long-term cycling stability(94％capacitance retention after 8000 cycles).The encouraging results might offer an effective strategy to optimize the TMSs for energy-storage devices.
