英文摘要	The development of lithium–sulfur batteries is limited due to its notorious "shuttle effect". Heteroatoms are introduced to the host materials to absorb the polysulfides and further to alleviate the shuttle effect. Herein, porous carbon (NSPC) was successfully prepared by template method and used as sulfur host material. The results show that NSPC has a high specific surface area (697.19 m2 g−1) and abundant heteroatom doping, which helps to enhance the capture and absorption of polysulfides. The prepared S@NSPC was loaded with 76% sulfur, and the composite electrode displayed excellent cycle stability because of its strong polysulfide absorption. The S@NSPC composite electrode shows high initial specific capacity of 741.8 mAh g−1 at 167.5 mA g−1, the capacity of the S@NSPC composite electrode remained 609.8 mAh g−1 after 500 cycles, and the attenuation per cycle was only 0.027%, showing good stability. © 2021, The Minerals, Metals & Materials Society.
