The negative electrode is organic protective layer.    TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The positive electrode comprises an electrically conductive agent facilitating movement of electrons, current collector, and a binder binding the sulfur-conductive agglomerated complex to the current collector.

The organic protective layer is conductive monomer, oligomer, or polymer from poly(p-phenylene), polyacetylene, poly(p-phenylene vinylene), polyaniline, polypyrol, polythiophene, poly(2,5-ethylene vinylene), acetylene, poly(peri-naphthalene), polyacene, or poly(naphthalene-2,6-diyl). EXAMPLE - A 67.5 pbw sulfur and 11.4 pbw ketjen black were mixed and subjected to ball milling after adding 200 g isopropyl alcohol for 3 days to obtain a slurry. The slurry was dried at 60 degreesC for 4 hours to obtain sulfur-ketjen black agglomerated complex. A test cell was assembled by adding the agglomerated complex to a binder solution prepared by adding 21.1 pbw polyethylene oxide into acetonitrile. The uniformly dispersed slurry was coated on a carbon-coated aluminum current collector to provide a positive electrode. The positive electrode, vacuum dried polyethylene separator, and a lithium negative electrode were laminated and put into a pouch. An electrolyte of 1 M LiN(CF3SO2) in 1,3-dioxolane/dimethoxyethane/diglyme (2/4/4 volume ratio) was injected and the pouch was sealed to provide a pouch-type test cell.
