Abstract
Processes for forming sulfur polymer cathodes include heating elemental sulfur above a melting point of sulfur to form molten sulfur having linear polysulfide chains, combining the molten sulfur with a cross-linker to form a sulfur polymer mixture, depositing a film of the sulfur polymer mixture on a substrate, and cooling the film of the sulfur polymer mixture to solidify the sulfur polymer mixture into a sulfur polymer. The cross-linker is a cyclic organic vinylic monomer comprising diene groups.
