Abstract

Official abstract text for this publication.

An electrode having a first set of stripes of sulfur-containing materials forming electroactive regions and a second set of stripes of a material forming non-electroactive regions interdigitated with the first set of stripes.

First claim

Opening claim text (preview).

What is claimed is: 1. A cathode of a battery having a lithium anode, consisting essentially of: a first set of stripes of mesoporous carbon and sulfur-containin materials forming electroactive regions on a substrate in a first layer, wherein each stripe in the first set of stripes comprises a co-extruded material composed of the mesoporous carbon and the sulfur-containing materials; and a second set of stripes of mesoporous metal oxide material forming non-electroactive regions interdigitated with the first set of stripes on the substrate in the first layer such that the first and second stripes reside adjacent each other on the substrate, the second set of stripes arranged to capture polysulfide generated by the sulfur-containing materials and to prevent the polysulfide from reaching the lithium anode; and a second layer of the material forming the non-electroactive regions arranged on the first and second sets of stripes opposite the substrate. 2. The electrode of claim 1 , further comprising a third set of stripes, wherein the second set of stripes comprises porous metal oxide and the third set of stripes comprises carbon. 3. The electrode of claim 1 , wherein the second set of stripes comprises carbon cloth. 4. The electrode of claim 1 , wherein the second layer comprises the material forming the non-electro active regions. 5. The electrode of claim 4 , wherein the second layer comprises an insulating layer forming a separator for a battery.
