英文摘要	Three-dimensional (3D) CNT/graphene-Li2S (3DCG-Li2S) cathodes with 81.4 wt % record Li2S loading have been realized through solvothermal reaction and a subsequent liquid-infiltration-evaporation coating method. The highly flexible, conductive 3D mesoporous interconnected network based on two-dimensional (2D) graphene nanosheets and one-dimensional (1D) carbon nanotubes (CNTs) provides highly efficient channels for electron transfer and ionic diffusion, and leads to a low solubility of polysulfides in electrolytes in charges/discharges. Without polymeric binders or conductive additives, the freestanding 3DCG-Li2S cathode exhibits record electrochemical performances including reversible discharge capacities of 1123.6 mAh g(-1) and 914.6 mAh g(-1), 0.02% long-term capacity decay per cycle and a high-rate capacity of 514 mAh g(-1) at 4 C. The reported 3DCG-Li2S aerogel with ultrahigh Li2S content presents promising application potentials in high-performance Li-S batteries.; National Natural Science Foundation of China [51372033, 21403031, 51202022, 61378028]; Fundamental Research Funds for Central Universities [ZYGX2013Z001, ZYGX2014J088, ZYGX2015Z003]; National High Technology Research and Development Program of China [2015AA034202]; 111 Project [B13042]; Specialized Research Fund for Doctoral Program of Higher Education [20120185120011]; Science & Technology Support Funds of Sichuan Province [2016GZ0151]; Sichuan Youth Science and Technology Innovation Research Team Funding [2011JTD0006]; Sino-German Cooperation PPP Program of China [201400260068]; SCI(E); ARTICLE; yfchen@uestc.edu.cn; weidong.he@uestc.edu.cn; 4; 820-826; 1
