Abstract
A method for making sulfur charged carbon nanotubes, the structure of the sulfur charged carbon nanotubes, and a cathode including the sulfur charged carbon nanotubes are described herein. The method comprises dissolving sublimed sulfur in a solvent to create a solution. The method further comprises adding carbon nanotubes to the solution. The method further comprises adding a polar protic solvent to the solution. The method further comprises removing the solvent from the solution.
Claims14
A method for making sulfur charged carbon nanotubes comprising
- dissolving sublimed sulfur in an initial solvent to create a solution;
- adding carbon nanotubes to the solution, each having an exterior wall;
- adding a polar protic solvent to the solution;
- and
- removing the initial solvent from the solution to form the sulfur charged carbon nanotubes, wherein
- a first plurality of sulfur particles is contained within each sulfur charged carbon nanotube;
- and
- a second plurality of sulfur particles is directly pi-bonded to the exterior walls of the sulfur charged carbon nanotubes.
