摘要： An electric cell module is provided, which enables operations of connecting terminals in one direction and which is, as a whole, highly rigid and has excellent resistance to breakage. A pair of rod bodies 3A and 3B are arranged parallel to each other to be oriented in opposite polarities. Each rod body contains a plurality of electric cells 1 connected in series through cell connector portions 2. An electrical connecting structure 4 is formed on one end face of each rod body. The structure connects the rod bodies electrically to each other. A coupling jig 5 is incorporated to surround at least one juxtaposed pair of cell connector portions present at the same longitudinal position in the rod bodies.

摘要： A nonaqueous electrolyte secondary battery having an enhanced capacity and a long charge/discharge cycle life is disclosed. The nonaqueous electrolyte secondary battery comprises a positive electrode housed in a case and containing a chalcogen compound as an active material, a negative electrode arranged in the case such that a separator is sandwiched between the positive and negative electrodes and containing a carbonaceous material as an active material that absorbs and discharges lithium ions and a nonaqueous electrolyte contained in the case and prepared by dissolving 0.5 mol/l to 1.5 mol/l of electrolytic salt selected from the group consisting of LiPF.sub.6, LiBF.sub.4, LiAsF.sub.6 and LiCF.sub.3 SO.sub.3 in a solvent mixture comprising at least one first nonaqueous solvent selected from the group consisting of noncyclic carbonate, cyclic carbonate, .gamma.-butyrolactone and acetonitrile and at least one second nonaqueous solvent containing selected from the group consisting of 1,2-diethoxyethane, 1,2-dimethoxyethane, 1,2-ethoxymethoxyethane, 1,3-dimethoxypropane, diethylether and tetrahydrofurane, the amount of said second nonaqueous solvent in the solvent mixture being so determined that the mol ratio ([S]/[Li]) of the second nonaqueous solvent [S]to lithium ions [Li]is 0.5 to 3.
