Vacant defects bring activity to multimetallic alloys for cathode redox reactions in lithium–sulfur batteries. In their Communication on page 3779 ff., J.‐Q. Huang et al. show that the introduction and in situ etching of an extrinsic metal to a monometallic compound activates the originally inert phase for kinetic propelling of polysulfide‐involving surface reactions at a high rate. Remarkable cycling stability is found at a high sulfur loading of 4.8 mg cm −2 .
