摘要：
The present invention pertains to battery cells comprising: (a) an anode; (b) a composite cathode comprising a mixture of
(i) an electroactive sulfur containing cathode material comprising one or more materials selected from the group consisting elemental sulfur, organo sulfur and carbon-sulfur compositions, and derivatives or combinations thereof; and
(ii) an electrically conductive additive; (c) a liquid electrolyte comprising a solvent for at least some anionic reduction products of said cathode; and, (d) a separator interposed between said composite cathode and said anode;
wherein said battery cell is characterized by a total thickness of the sum of the composite cathode thickness and the separator thickness of up to about 125 micrometers. The present invention also pertains to methods of making such cells.
