摘要:
A battery case for containing several cells as a battery, and having battery terminals, within the case contour and accessible through windows, to be engaged by external receiving terminals of an apparatus to be served; with the battery terminals arranged to apply proper polarity, whether the case is applied right side up, or in inverted mode, at random.

A fatty polyamide is employed as a seal or a protective coating in order to prevent alkaline electrolyte from wetting a surface in an alkaline galvanic cell.
摘要:
Electrochemical cell having a metal housing, a metal top, and a resilient ring compressed between the edge region of the top and the internal surface of the housing, which edge ring embraces the edge region of the top, and has a peripheral annular projection on its radially outer surface which engages the internal surface of the housing, whereby the compressive sealing forces in the ring are localized in an annular region of the ring.
摘要:
A battery cartridge having a hollow shell case with walls of minimum thickness, and of minimum weight and dimensions, over the minimum weight and volume dimensions of the contained battery cells, for use in portable devices such as radios, cameras, computers and the like, to thereby limit the space requirements of the cartridge and to limit the weight in excess of the cell weights.
摘要:
A primary electrochemical cell includes a device having essentially unidirectional current flow and low voltage drop in the current flow direction characteristics. Electrically, the device is internally connected between one of the poles of the cell and the associated electrode in such a manner that current flow in a recharging direction within the primary cell is prevented so that both recharging and reverse polarity operation of the primary cell are precluded.

An assembly for rapidly mounting a battery to an electrical device includes a supporting camming plate with a large opening and smaller notches at opposite sides of the opening with the plate mounted across a recess in the electrical device. The battery case has an protruding member with a pair of lugs extending radially from the protruding member. Each of the lugs includes a symmetrically shaped camming portion of gradually increasing and then decreasing extension from the inward surface of the lug. The protruding member is adapted to be inserted into the opening in the plate by passing the pair of lugs through the notches and after being inserted through the opening to be given partial rotation to carry the lugs out of alignment with the notches so that the camming portion is under the plate.

An inter-electrode insulating seal comprising lithium fluoride for use with high temperature batteries having lithium fluoridesaturated molten salt electrolytes. Means are provided for mitigating the thermal expansion characteristic of lithium fluoride.
摘要:
An electrochemical device having a resilient, electrolyte resistant inner lining and top (e.g., of plastic) and connections between the electrodes of the device through the inner top to the device terminals which are sealed by a compression fit between the terminal connecting post and resilient inner top. A hole or port in the resilient member at the point of connection carries the terminal connecting post which consists of a deformable electrical conductor of relatively soft lead. This deformable lead post is made to yield and expand against the plastic lining to form a liquid seal compression fit. The expansion is provided by the engagement of a threaded male member, e.g., a bolt, with a threaded female member, e.g., a lock nut, one of the members being embedded in the lead post and reacting against and deforming the lead upon engagement of the threaded members. This seal has particularly utility in a sealed or resealably safety valved battery and other electrolytic cells.
摘要:
A lead accumulator or battery consists of a plurality of cells each having positive and negative plates. A cover provided for each of the cells has openings therein and cell connectors electrically and mechanically interconnect the cells. The cell connectors are disposed below the upper edge of the cell covers and provide a rigid interconnection between the cells. The disposition of the cell connectors below the upper edge of the cell cover protects against inadvertent short circuiting caused by contact with metal objects.
