Patent ID: 7250233

Claim:
A lithium-sulfur battery comprising: a positive electrode having an electron-conductive path and an ion-conductive path and comprising: a positive active material including an active sulfur in the form of solid phase elemental sulfur (S8) and/or a polysulfide solution, and pores of an average size greater than or equal to substantially 5 μm and less than and including 15 μm having both electron-conductive and ion-conductive properties, where the active sulfur is disposed in the pores during an electrochemical reaction of the lithium-sulfur battery; a negative electrode comprising a negative active material selected from the group consisting of a lithium metal, a lithium-containing alloy, materials which can reversibly intercalate/deintercalate lithium ions, or materials which can reversibly form a chemical compound with lithium; a separator interposed between said positive and negative electrodes; and an ion-conductive electrolyte.
