摘要： A lithiated manganese oxide for use in primary lithium cells is described. The lithiated manganese oxide can be prepared by exposure to a lithium source under conditions that result in the formation of a modified manganese oxide phase. When the modified phase is used in a primary lithium cell, the operating voltage of an electrochemical cell containing the lithiated manganese oxide increases relative to the operating voltage of a cell containing a manganese dioxide that is not exposed to the lithium source.

摘要： The present invention relates to coiled electrode assemblies having conductive tabs, methods of attaching the conductive tabs to the coiled electrode, and electrochemical cells employing such assemblies. In the process of the invention, the conductive tab area of an electrode plate (1) coated with active material is pierced with opposing, offset piercing plates (2) having raised surface probes (3) which penetrate the conductive tab area. The resulting area is cleared of active material, and a conductive tab is welded to the thus treated area resulting in an electrode plate having a strong integrated tab assembly.

摘要： Disclosed is a process for treating manganese dioxide containing ion-exchangeable cations by replacing the ion-exchangeable cations present in the manganese dioxide with lithium by a process comprising first replacing ion-exchangeable cations present in the manganese dioxide with hydrogen. This readily is accomplished by slurrying the manganese dioxide in an aqueous acid solution. The resulting acidic manganese dioxide then is neutralized with a basic solution of a lithium containing compound, such as lithium hydroxide. This neutralization step serves to accomplish replacement of the previously introduced hydrogen, by ion-exchange, with lithium. The manganese dioxide then is washed with water, dried, and heat-treated at an elevated temperature, in conventional manner, to convert the gamma manganese dioxide to a mixture of the gamma and beta forms, which then is used as the active cathodic component in an electrochemical cell.

摘要： An electrochemical cell (30) having an on-cell tester (38) for visually indicating the condition of the cell (30) is provided with an electrically conductive metal ring (10) pressed onto the negative terminal at the crimp seal end of the cell (30) to permit the tester lead to make an electrical contact with the negative terminal without shorting across the positive terminal of the cell (30). The ring (10) has a cylindrical wall portion (12) or gripping means which frictionally grips a corresponding mating cylindrical wall portion on the negative terminal and also has a flange portion (16) adjacent the positive terminal. A layer of electrically insulating material (18) disposed between the flange and positive terminal prevents electrical contact between the terminals. The tester lead is either permanently electrically connected to the ring (10) or intermittently connected by the user, depending on the type of tester used.

摘要： The present invention is directed to a cartridge (100) comprising a rectangular base (102) and four side walls (104, 106, 108, 110) which form a cavity (112) into which an energy pack (114) or a plurality of individual battery cells (116), either primary or secondary, are locatable. The cartridge (100) is securable to an electrical apparatus by a latching mechanism (120). Alternatively, the cartridge (100) can be integral therewith. In a first embodiment, a plurality of cells are locatable such that their positive and negative contacts are positioned against a set of positive (132a-f) and negative (134a-f) contact areas located along the first and second side walls. The first embodiment optionally comprises a contact arm, locatable substantially parallel to the second side wall, which includes a plurality of positive contact areas corresponding to and across from the negative contact areas located on the second side wall. A plurality of cells, having a shorter length than the battery cells (116) locatable between the first and second side walls, are locatable between the contact arm and the second side wall. The cartridge (100) also provides circuitry to recharge the energy pack and/or secondary cells located therein.

摘要： Disclosed is a method for the production of slurries, which are uniform in density and consistency, and also an apparatus for the transfer or conveyance of a slurry and the simultaneous densification thereof through the intermediary of vacuum pumping. The method comprises a bag slurry forming process involving mixing dry anode components within a sealable, gas-tight, liquid impervious, flexible, collapsible bag (20); and, then adding a wet component (26) to the bag, collapsing said bag, and tumbling-kneading the components to form a blended slurry. The apparatus (40) is designed for the vacuum pumping of a slurry, particularly a zinc-containing slurry utilized in the preparation of zinc anodes for alkaline batteries, which facilitates the transfer of the slurry and the concurrent densification thereof in conjunction with the elimination of any gas bubbles which are entrapped in the slurry.
