TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compounds: The organopolysulfide of formula (II) has a synthesis formula of C16H18O4S2, and it is produced by a reaction between 1,2-dimethoxybenzene and sulfur monochloride. The organopolysulfide of formula (III) has a synthesis formula of (C8H8O2S3)n, and it is produced by a reaction between 1,3-dimethoxybenzene and sulfur monochloride. The compound of formula (IV) has synthesis formula of (C14H10O2S8)n. The organopolysulfide can also be of formula (V). The organopolysulfide of formula (VII) has synthesis formula of C6S18.X = H or CH3.Preferred Components: The conductive agent comprises carbon black, acetylene black and/or vapor growth carbon fiber. EXAMPLE - 52.09 g of cyclic bis(2,5-bis-dithio-1,4-dimethoxybenzene), 14.81 g Super P black, 29.11 g polyethylene oxide, 3.98 g lithium salt and 734 ml acetonitrile were mixed to prepare a cathode active material. The material was coated on a nickel film of thickness 10 microns and dried. The dried electrode was vacuum pressed to fabricate the cathode. Lithium metal was roll-pressed thinly on the copper thin film to fabricate an anode. A porous polypropylene film was disposed between the cathode and anode and then a lithium/sulfur polymer electrolyte battery was fabricated using 1 M lithium perchlorate dissolved in solvent mixture of ethylene carbonate and dimethyl carbonate in ratio of 1:1 as electrolytic solution. The battery had primary specific discharge capacity of 240 mAh/g, initial charging recovery rate of 114.5%, and primary charging/discharging efficiency of 92.5%.
