Abstract: Alkali (or other active) metal battery and other electrochemical cells incorporating active metal anodes together with aqueous cathode/electrolyte systems. The battery cells have a highly ionically conductive protective membrane adjacent to the alkali metal anode that effectively isolates (de-couples) the alkali metal electrode from solvent, electrolyte processing and/or cathode environments, and at the same time allows ion transport in and out of these environments. Isolation of the anode from other components of a battery cell or other electrochemical cell in this way allows the use of virtually any solvent, electrolyte and/or cathode material in conjunction with the anode. Also, optimization of electrolytes or cathode-side solvent systems may be done without impacting anode stability or performance. In particular, Li/water, Li/air and Li/metal hydride cells, components, configurations and fabrication techniques are provided.

Abstract: An accommodation for holding and connecting batteries, especially lithium batteries of the type ordinarily employed for photographic purposes, but in conditions where moisture constitutes a hazard, such as in electronically controlled plumbing fixtures. The accommodation is provided with a pocket-like envelope of elastomeric material with an inner surface that matches the outer surface of the battery to be accommodated therein and with an opening at one end to insert the battery therethrough and closed at the other end. The accommodation has a plate with resilient contacts on its inward-facing side inside the envelope at the closed end and the envelope is surrounded by an inward-extending collar in the vicinity of the open end that engages the battery from behind and secures it, forcing it against the contacts. A connecting cable extends moisture-tight out of the closed end.

Abstract: The invention relates to a housing which receives dry cells in an in-line or end to end orientation. The invention includes features which prevent the incorrect orientation by preventing dry cell terminals making contact with the necessary components. In this way, it prevents premature dissipation of dry cells or their impairment. The mechanism by which these features do this is to recess one terminal namely that terminal which would be contacted by the positive terminal of a dry cell. In this way, the negative terminal of a dry cell can never make electrical connection. Another feature of the invention is the provision of an aperture having a profile of a silhouette of a dry cell, which has advantages in low light situations, saves material, and allows for relatively easy extraction of dry cells from the cartridge.

Abstract: Plastic hydrophobic material is bonded to a metallic sheet member such that the resulting sandwich structure is impervious to electrochemical delamination.

A resulting sandwich structure of the metallic sheet member and the first and second films are compressed and simultaneously the temperature is raised to the sintering temperature of the hydrophobic film material. The first and second films are caused to melt sufficiently at their interfaces to cause an intermixing of the juxtaposed material thereof throughout the region of the border portions and throughout the regions of the perforations.

Abstract: The method of making standby water-activated primary current sources, according to the invention, resides in that concurrently with hermetical sealing of the ends and edges of the negative electrodes, a flanged rim is provided along the perimeter of each of the negative electrodes, the height of said flanged rim being in excess of the thickness of the bipolar electrode and the separator. The flanged rim forms an angle from 90.degree. to 180.degree. with the electrode surface and is provided with at least one shoulder for passing the water and gases and for current leadout. The bipolar electrodes are interlaid with the separators, whereupon the adjacent portions of the flanged rims are welded together into an integral block of bipolar electrodes. The proposed method makes it possible to completely dispense with manual labor and simplify the production techniques.
