TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: At least 25 wt.%, preferably 36 wt.% of the electrochemically active material is accessible to electrons and ionic charge carriers. The electrochemically active material is non-molten. The positive electrode contains 20-80 wt.%, preferably 40-60 wt.% of the electrochemically active material, and 5-40 wt.%, preferably 8-24 wt.% of the electronically conductive material.Preferred Material: The ionically conductive material of the positive electrode is provided in a solid-state form, and is chosen from polymeric electrolytes, ceramic electrolytes, glass electrolytes and/or beta-alumina compounds. The ionically conductive material comprises 20-80 wt.% of an aprotic organic liquid, a gelling agent and an electrolyte salt. The positive electrode further comprises at least one of binders, electro-catalysts, surfactants, dispersants and protective layer forming additives.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The solid-state ionic conductor comprises an electrolyte salt that form a complex with compounds chosen from polyether compounds, polyimine compounds, polythioether compounds, polyphosphazene compounds, polyalkylene oxide compounds, polyethylene oxide compounds and/or amorphous polyethylene oxide compounds.Preferred Material: The electronically conductive material is chosen from carbon black, compounds with conjugated carbon-carbon or carbon-nitrogen double bonds, electronically conductive polymers, polyaniline compounds, polythiophene compounds, polyacetylene compounds and/or polypyrrole compounds. EXAMPLE - A positive electrode film was made by mixing (in weight%) elemental sulfur (45), carbon black (16), amorphous polyethylene oxide (16) and lithium trifluoromethanesulfonimide (16), and 2,5-dimercapto-1,3,4-dithiadiazole (5) in a solution of acetonitrile. The components were stir-mixed for two days until the slurry was well mixed and uniform. Subsequently, a thin positive electrode film was cast directly on a stainless steel current collector, and the solvent was evaporated at ambient temperatures. The resulting positive electrode film had weight of 0.0028 g/cm2. Subsequently, a polymeric electrolyte separator was made by mixing the amorphous polyethylene oxide with lithium trifluoromethanesulfonimide in a solution of acetonitrile. The components were stir-mixed for two hours until the solution was uniform. The resulting separator slurry was measured and cast into a retainer on a release film, and the solvent was evaporated at ambient temperatures. The resulting electrolyte separator film had weight of 0.0144 g/cm2. The positive electrode film and the polymeric electrolyte separator were assembled under ambient conditions, and vacuum dried over night to remove moisture prior to transferring into an argon glove box for final cell assembly with a lithium negative electrode film. Subsequently, after assembling the cell, the cell was compressed at 2 psi and heated at 40 degrees Celsius for 6 hours. After heating, the layers of lithium, electrolyte separator and the positive electrode were well adhered. Lithium contamination in the cell was removed, and the cell was cycled to a constant capacity corresponding to delivering 330 mAh per gram of the active-sulfur in the positive electrode film. The cell had very consistent performance.
