The invention relates to complex framework materials (CFMs) for lithium-sulfur batteries. The CFMs include a CFM host and a coating applied to the CFM host, which includes one or more of an electronic conductor, a lithium ion conductor and a functional catalyst. Further, sulfur is infiltrated into the CFM host creating a sulfur-carbon linkage serving as effective anchors for trapping polysulfides. The systems have been tested in coin cells and pouch cells under lean electrolyte conditions of 3-4 μl/mg of electrolyte to sulfur ratios showing promise and feasibility.
