英文摘要The shuttle effect of polysulfides severely limits the practical application of lithium-sulfur batteries. Herein, the lithium-rich Li[Li0.2Ni0.2Mn0.6]O-2/hierarchical porous graphitic carbon composite (LLNM/HPGC) is designed and synthesized as host material for lithium-sulfur batteries, aiming to restrict the shuttle effect of polysulfides via physical entrapment from 3D HPGC and accelerate the conversion of polysulfides from the lithium-rich LLNM as catalyst. Benefiting from the well-constructed host framework, 1glycerinum-LLNM/2HPGC@sulfur (1Gly-LLNM/2HPGC@S) shows higher specific capacity of 651 mAh g(-1) after 200 cycles at 0.5C than that of 546.3, 422.8, 476, and 421.7 mAh g(-1) for HPCG@S, Gly-LLNM@S, 1Gly-LLNM/3HPGC@S, and 1Gly-LLNM/5HPGC@S. Therefore, this work demonstrates a promising route to inhibit the shuttle effect of polysulfides for lithium-sulfur batteries.
