Abstract

A sulfur particle containing a core of elemental sulfur having homogeneously dispersed particles of a conductive carbon and branched polyethyleneimine; and a coating of branched polyethyleneimine (bPEI) encapsulating the core is provided. In the sulfur particle the dispersed particles of conductive carbon are associated with the bPEI. A cathode having an active material containing the sulfur particles and a sulfur loading of 1.0 mg S/cmto 10 mg/cmand a battery containing the cathode are also provided.
