摘      要：In article number 2001201, Zhen Li, Yunhui Huang, and co‐workers present an ultrathin, lightweight, and highly conductive Bi2Te2.7Se0.3 interlayer on the separator surface that can not only enhance the capacity utilization of the sulfur electrode, but also improve the cycling stability due to the strong interaction between polysulfides and the intrinsic antisite defects. This work proposes a defect engineering strategy accompanied with a facile method for developing more practical Li‐S batteries.
