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.

A process for forming sulfur polymer cathodes, the process comprising:
- heating elemental sulfur above a melting point of sulfur to form molten sulfur comprising linear polysulfide chains;
- combining the molten sulfur with a cross-linker to form a sulfur polymer mixture, the cross-linker being a cyclic organic vinylic monomer comprising diene groups;
- 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 without sulfur crystallization.
