Sulfur containing nanoparticles that may be used within cathode electrodes within lithium ion batteries include in a first instance porous carbon shape materials (i.e., either nanoparticle shapes or 'bulk' shapes that are subsequently ground to nanoparticle shapes) that are infused with a sulfur material. A synthetic route to these carbon and sulfur containing nanoparticles may use a template nanoparticle to form a hollow carbon shape shell, and subsequent dissolution of the template nanoparticle prior to infusion of the hollow carbon shape shell with a sulfur material. Sulfur infusion into other porous carbon shapes that are not hollow is also contemplated. A second type of sulfur containing nanoparticle includes a metal oxide material core upon which is located a shell layer that includes a vulcanized polymultiene polymer material and ion conducting polymer material. The foregoing sulfur containing nanoparticle materials provide the electrodes and lithium ion batteries with enhanced performance.

Sulfur containing nanoporous materials, nanoparticles, methods and applications

A reactor for producing a sulfur-infused carbonaceous material as a cathode material for use in a Li&#x2014;S battery is described, including a reactor body capable of withstanding a pressure from about 1 atm to about 150 atm; and an inner sulfur-resistant layer at the inner surface of the reactor, wherein the inner layer is inert to sulfur vapor at a temperature from about 450&#xb0; C. to about 1000&#xb0; C.
