The work describes a room temperature battery that uses an electrolyte of Na (sodium) in a propylene carbonate liquid carrier with electrodes made of graphene flakes with Mo and S embedded in the graphene framework. I don't know what the author of the article posted was trying to say when referring to molton Na-S, since it is not part of the battery described in the research, nor part of the manufacturing process. Probably the author did a search on Na-S for background, and not understanding how this differed, stuck it in.
