Abstract
Lithium-sulfur batteries possess the potential to significantly improve upon current commercialized battery technology. To produce viable cathodes for lithium-sulfur batteries, sulfur must be encapsulated in an electrically conducting network. This study demonstrated that through the facile synthesis technique of coaxial electrospinning, sulfur could be encapsulated by polyaniline, an electrically conducting polymer. Although cathodes fabricated with these electrospun fibers have yet to achieve electrochemical performance demonstrated in literature, the material has exhibited promising performance that can be substantially improved by optimizing the cathode manufacturing process. A promising alternative application - using electrospun polyaniline fibers of high purity as the electrode material for a supercapacitor - was explored as a direct result of the advances made during this project.
