While members of the Li–S battery research community are becoming more conscious of the practical testing parameters, the widespread commercialization of S‐based batteries is still far from realization. Particularly, the metallic Li used as the anode poses potential safety and cycle stability concerns. Alternatively, other S‐battery configurations without a Li anode, i.e., lithium‐ion, Li 2 S, or S batteries, do not suffer from the same safety concerns and can possibly serve as better methods to bring room‐temperature S‐based battery technologies to industry. However, whether Li 2 S or S will be used as the initiating cathode material remains unclear as each offers their own unique advantages and disadvantages. Here, both S and Li 2 S as cathodes are briefly discussed and the key benefits of Li 2 S are highlighted.
