Claim 0:
1. A rechargeable alkali metal-sulfur cell selected from lithium-sulfur cell, sodium-sulfur cell, or potassium-sulfur cell, said alkali metal-sulfur cell comprising:
(a) an anode active material layer and an optional anode current collector supporting said anode active material layer;
(b) a cathode active material layer and an optional cathode current collector supporting said cathode active material layer; and
(c) an electrolyte with an optional porous separator layer in ionic contact with said anode active material layer and said cathode active material layer;
wherein said cathode active material layer contains multiple particulates of a sulfur-containing material selected from a sulfur-carbon hybrid, sulfur-graphite hybrid, sulfur-graphene hybrid, conducting polymer-sulfur hybrid, metal sulfide, sulfur compound, or a combination thereof and wherein at least one of said particulates has a diameter or thickness from 100 nm to 50 μm and comprises one or a plurality of particles of said sulfur-containing material that are partially or totally encapsulated by, embedded in, dispersed in, or bonded by an electrically and ionically conducting network of cross-linked polymer chains having a lithium ion conductivity from 10−8 to 5×10−2 S/cm and an electron conductivity from 10−8 to 103 S/cm, wherein said conducting network of cross-linked polymer chains comprises a conjugated polymer selected from polyacetylene, polythiophene, poly(3-alkylthiophenes), poly(isothianaphthene), poly(3,4-ethylenedioxythiophene), alkoxy-substituted poly(p-phenylene vinylene), poly(2,5-bis(cholestanoxy) phenylene vinylene), poly(p-phenylene vinylene), poly(2,5-dialkoxy) paraphenylene vinylene, poly [(1,4-phenylene-1,2-diphenylvinylene)], poly(3′,7′-dimethyloctyloxy phenylene vinylene), polyparaphenylene, polyparaphenylene sulphide, polyheptadiyne, poly(3-hexylthiophene), poly(3-octylthiophene), poly(3-cyclohexylthiophene), poly(3-methyl-4-cyclohexylthiophene), poly(2,5-dialkoxy-1,4-phenyleneethynylene), poly(2-decyloxy-1,4-phenylene), poly(9,9-dioctylfluorene), polyquinoline, a derivative thereof, a copolymer thereof, a sulfonated version thereof, or a combination thereof.
