Carbon-Sulfur Based Core-Shell Materials Compositions, Methods, and Applications

摘要

A materials composition and a method for preparing the materials composition provide: (1) a core material comprising a reactive carbon material-sulfur material composite; surrounded by and chemically coupled with (2) a shell material comprising a reactive sheath material. The material composition is useful within electrodes within electrical components including but not limited to electrochemical gas cells, supercapacitors and batteries where enhanced cycling may be realized.

1. A method for preparing a material composition comprising:
combining a reactive carbon material and a sulfur material to form a reactive carbon material-sulfur material composite core material; and combining the reactive carbon material-sulfur material composite core material with a complementary reactive sheath material to provide a reactive carbon material-sulfur material core material surrounded by and chemically coupled with the complementary reactive sheath material as a shell material.
