abstract = {The major hurdle in Li-S battery commercialization is the
severe shuttle effect and sluggish reaction kinetics of
polysulfide conversion during charge-discharge cycling.
Herein, to overcome these barriers, we designed and
synthesized Zn defective Zn/Co oxide (ZDZCO) nanosheets, a
cation-vacancy-rich bimetallic oxide for the construction of
a multifunctional polysulfide-blocking layer. Both
theoretical and experimental studies have comprehensively
demonstrated that the ZDZCO shows robust binding capability
towards polysulfides and a high catalytic ability for fast
polysulfide conversion. Through a facile coating process,
the multifunctional ZDZCO polysulfide-blocking layer is
incorporated on a commercial polypropylene separator,
forming a composite separator. The resultant separator
facilitates an ultrahigh sulfur loading of 21.06 mg cm-2 and
an areal capacity as high as 24.25 mAh cm-2. This study
illuminates a promising and practical strategy to construct
high-performance Li-S batteries with high sulfur loading.},
