      abstract     = {The extraordinary energy density and low cost enable
                      lithium-sulfur (Li-S) batteries to be a promising
                      alternative to traditional energy storage systems. The
                      principal hurdle facing Li-S batteries is the unsatisfactory
                      utilization of sulfur cathodes. The detrimental shuttle
                      issue of polysulfides and the sluggish charge transfer
                      kinetics result in quick capacity degradation of Li-S
                      batteries. An MFLC hybrid material composed of
                      manganese-iron layered double hydroxides (Mn-Fe LDH) and
                      carbon nanotubes (CNT) has been developed. Such
                      heterostructure combines the advantages of effective
                      chemical bonding of Mn-Fe LDH towards polysulfides with the
                      high conductivity of CNT. When modified on a polypropylene
                      (PP) separator, the hybrid material is proven to
                      significantly inhibit the shuttle issue of polysulfides and
                      accelerate their redox reaction kinetics. Li-S batteries
                      with MFLC-modified separators revealed considerably improved
                      electrochemical performance. A high initial capacity of
                      1138 mA h g−1 and 70 $\%$ capacity retention after 200
                      cycles were achieved at 0.2 C. The enhanced sulfur
                      utilization can be directly evaluated from the discharge
                      voltage plateaus. The results indicate a new solution for
                      the practical application of Li-S batteries and provide a
                      simple approach to determine the efficiency of sulfur
                      utilization.},
