Abstract: An assembly of accumulator cells juxtaposed to form a unit comprises a peripheral binding and holding system. The peripheral binding is an insulative material strap having an insulative material buckle. The insulative material(s) are resistant to the accumulator electrolyte. The strap is fastened by the buckle and is immobilized vertically against the side walls of the unit. The holding system comprises a rigid flat support made from an electrolyte resistant material disposed beneath the cells and extending longitudinally thereof. To this are attached at least two carrying straps each disposed between two cells and defining a respective handle above the cells.
Abstract: Lithium batteries used for an aeration or breathing apparatus, such as gas masks or protective suits, are enclosed in a housing, and the enclosure has a predetermined breaking point to release gases which may accumulate in the interior. The housing surrounding the lithium batteries has a closure, which opens when the compressed gases are released, to allow the gases to be safely discharged to the outside.
Abstract: The invention relates to a multi-cell battery of electro-chemical cells of the type which is likely to be severely damaged and which is apt to release a substantial quantity of heat when short-circuited.According to the invention, the multi-cell unit is provided with a certain filler in the space between the constituent electrochemical cells, which is either a solid with a melting point in a predetermined range of temperature, or a liquid. The filler ought to be electrically non-conducting, and its quantity ought to have an adequate heat capacity and it ought also to be capable to transfer heat to adjacent cells.
Abstract: Electrochemical cell or battery housing modules are joined together to form an integral vibration-resistant multi-unit battery through adherence together of corresponding ribs formed on the outer walls of the modules.
Abstract: Storage cell connection for at least two storage cells based on alkali metal and chalcogen with each cell having at least one anode space and a cathode space which are separated from each other by an alkali ion-conducting solid electrolyte and are bounded at least in some regions by a metallic housing, as well as are provided with at least one first and one second connecting element. At least one fastening element is provided on the surface of the housing, by means of which fastening element the first connecting element of the first storage cell can be locked, together with a second connecting element of the second storage cell on this surface. The second connecting element of the first storage cell is likewise designed for the detachable connection to the fastening element of a third storage cell.
Abstract: An electric battery pack is manufactured by a process whereby an outer insulating casing has contact strips partly inserted through apertures in opposed sides thereof adjacent a closed bottom thereof. A series arrangement of connected batteries is inserted into the casing until the positive and negative poles of the series arrangement engage against the contact strips. A cover having integral inward projections is pressed towards and against the casing to close an open end thereof, the inward projections being stressed and deforming against end batteries to secure all the batteries immovably in position, and the cover being welded to the casing. The inner ends of the contact strips are then welded or soldered to the poles of the series arrangement from outside the casing through access orifices in the closed bottom of the casing.
Abstract: High-temperature storage battery with at least two or more storage cells of the alkali metal and chalcogen type, with each cell bounded by a metallic housing, and wherein a defined number of storage cells forming a module are combined. The housing of each storage cell is formed by at least two concentrically arranged housing elements, which are separated from each other by electrical insulation, and the storage cells of each module are arranged in a defined manner, and adjacent storage cells are connected to each other at least in some regions via their outer housing elements.
Abstract: Two-dimensional arrays of polarized energy-generating or energy-storing elements (20A, 20B, . . . , 20D; 21A, . . . , 21D; 22A, . . . , 22D; 23A, . . . , 23D; 24A, . . . , 24D; 25A, . . . , 25D), such as solar cells, batteries, thermoelectric generators or capacitors are formed as a matrix of rows and columns of elements, with the elements of each column being connected in series and the junctions between the series-connected elements in each column within the matrix being connected, in sequence, first to the corresponding junction in one of the adjacent columns and then to the corresponding junction in the other one of the adjacent columns. By connecting the junctions (32, 33) of alternate pairs of elements in the left hand column of the matrix to the respective junctions (32A, 33A) in the right hand column of a matrix having an even number of columns, the mathematical equivalent of a tubular matrix of elements is formed.
Abstract: A flexible film laminate, according to the invention, can be applied directly to the cardboard tubing of dry cell batteries during the manufacture of same.In a preferred arrangement the laminate comprises, a first layer of a plastics film 1, a second layer of discrete areas of colored pigments 2, a third layer of adhesive 3, a fourth layer of a metallic deposit 4 on the surface of a fifth layer, said fifth layer of a plastics material 5, a sixth layer of adhesive 6, a layer of finely divided clay mineral particles 7, a layer of bleached kraft paper 8 and a final layer of uncured heat sensitive adhesive 9.

Abstract: This specification teaches a battery structure of lightweight construction. Such a battery is particularly useful as the power source for a space satellite. The battery structure includes a plurality of cells. Each cell has a plurality of non-strengthened cell walls which contact other nonstrengthened cell walls when the cells are in an assembled condition. Each cell also has strengthened cell walls which do not contact any other cell walls when the cells are in an assembled condition. Structurally strengthened end plates are located at opposite ends of the assembled cells to provide support for any nonstrengthened cell walls of the cells coming in contact therewith. Structure is provided for holding the structurally strengthened end plates and cells in an assembled condition. By strengthening only exposed walls, a lightweight battery construction is achieved.
Abstract: A lead storage battery with positive and negative plates, the contact lugs of which respectively are connected with one another by lug bridges. The grid upper part of each plate grid is covered with an acid resistant synthetic material covering, which synthetic material covering surrounds the contact lugs acid-tight, the synthetic material covering being connected acid tight with the cell cover or one-piece composition case cover. The lug bridges are connected with one another outside of the acid space of the contact lugs.
