The plastic tubular member is unitary with the plastic cover and a reinforcing boss on the cover is annular and an annular stabilizing flange unitary with the metal barrel is embedded in this reinforcing boss. The metal barrel is separated from the interior of the electrochemical cell so that the metal barrel need not be resistant to the electrolyte and so that there is no potential leakage path between internal threads on the metal barrel and external threads on the plastic tubular member. The foregoing Abstract is merely a resume of general applications, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: Described herein is a contact arrangement for a battery cell of a galvanic battery. The battery cell comprises a positive mass layer (6, 106) and a negative electrode layer (11, 111). A separator layer (5, 105) separates the positive mass layer (6, 106) and the negative electrode layer (11, 111) from each other.

An additional insulation layer (9, 13, 113) made of a tough and adhesive material and bounded by the case (1, 2, 101, 102) is provided so as to maintain the hermetic nature of the case despite the passing-through of a contact unit (12, 14, 16, 22, 23, 24, 116).

Abstract: The invention discloses a lid made of plastic (1,20,30) for lead-acid accumulator batteries wherein at least each opening for the passage of the positive poles presents an externally cylindrical collar (6,21,31) having nearly the same diameter as the openings, wherein said collar (6,21,31) receives in its interior the bush (7,15,34) blocking the pole (4,23,33) of the accumulator battery and is connected with the lid through an elastic diaphragm (10,25,35) having a circular cross-section, the upper edge of said diaphragm being attached to the lid and the lower edge is connected with the outer surface of the collar.According to a preferred embodiment of the invention the elastic diaphragm (10,25) has a toroidal shape.According to another embodiment the elastic diaphragm (35) acquires the shape of a bellows with a vertical axis.

Abstract: A flat lid for lead-acid accumulators contains openings which are provided with elastic seats for the accommodation of poles. Around each opening for the passage of the poles of an accumulator is provided an elastic diaphragm, the longitudinal profile of which is suited to be elastically deformable in its axial direction. A pole of the accumulator is connected with the diaphragm by means of a ring-shaped seat which is present at the end opposed to the area for the connection with the lid. When a lengthening of the pole of the accumulator eventually occurs during its life-span, it will be absorbed by the deformation of the diaphragm so that the lid will not be subjected to stresses which might otherwise damage or disconnect it from the accumulator with serious consequences.

Abstract: A hermetically sealed primary electrochemical cell is described together with a method for its production which is especially useful with electrochemical systems which include an electrolytic solution having a volatile solvent material. The hermetic seal is achieved by welding a glass-to-metal seal within a single opening in the outer casing of the primary electrochemical cell. In order to avoid volatilization of the solvent material during the welding process, a temporary seal is formed within the outer cell casing immediately above the elements forming the electrochemical system so the solvent material is insulated from the heat and any volatilized solvent material is effectively prevented from escaping during the time required to complete the weld. In a preferred form of the method, the entire assembly is chilled prior to the welding step to further reduce volatilization of the solvent material.

Abstract: A storage battery comprising a thermoplastic cover having a hollow metallic terminal therein and a thermoplastic case having an upstanding metallic core member passing through the terminal is assembled using vibratory energy. The cover and the case undergo relative reciprocating translating motion while under the influence of a static force applied in a direction perpendicular to the plane of the mating surfaces between the cover and case. The terminal and core are dimensioned for providing a peripheral clearance around the core in the direction of the reciprocating motion at least equal to the peak-to-peak displacement of the vibratory motion. The gap existing between the core and the terminal when the battery is assembled is sealed.
