Abstract
By shielding zinc stannate ZTO viz Zn2SnO4 nanoparticles with reduced graphene oxide RGO as well as multiwall carbon nanotubes MWCNTs we have successfully created ZTO/RGO/MWCNTs composites via a facile hydrothermal process In the designed hybrid nanostructure acting as the strut and bridge to open the graphene sheets 3D RGO/MWCNT nets not only tackle the problem of volume expansion and the aggregation of ZTO nanoparticles but also maintain the integration of anode materials for high electrochemical performance As a result the resultant anode material shows high reversible capacity superior rate capacity and longrunning cycle performance for lithium ion batteries LIBs For instance a excellent reversible capacity of 9159 mAh g−1 was obtained at the current density of 100 mA g−1 after 340 cycles Our study demonstrates significant potential of ZTO/RGO/MWCNTs as anode materials for LIBsThis research was supported by the National Natural Science Foundation of China 51572194 the Key Projects of Tianjin Municipal Natural Science Foundation of China 14JCZDJC32200 LPMT CAEP KF14006 Academic Innovation Funding of Tianjin Normal University 52XC1404 Scientific Research Foundation for Returned Overseas Chinese Scholars of State Education Ministry Training Plan of Leader Talent of University in Tianjin and the program of Thousand Youth Talents in Tianjin of China XS and YZ thanks support from the Natural Science and Engineering Research Council of Canada and the Canada Research Chair Program
