摘要： An elongate, generally tubular, air depolarized electrochemical cell (10) comprising a cathode (14), including an air cathode assembly (26), extending about the tubular circumference, and along the tubular length, of the cell (10), an anode (12), a separator (16) between the anode (12) and the cathode (14), electrolyte, a top closure member (177, 200), and a bottom closure member (114, 202). The cathode assembly (26) is fixedly held, by a friction fit, in a slot (116) at the bottom of the cell. The slot can be developed, for example, by inner (110) and outer (114) walls of a cathode can (28), by inner (226) and outer (224) walls of a bottom closure member (202), or by an outer wall (114) of a cathode can (28) and an opposing outer wall of a plug (128) on the interior of the cell. Preferably, bottom closure structure of the cell (10) and receives a bottom edge portion (44) of the cathode current collector (32), and makes electrical contact with the bottom edge portion (44), preferably at an inner surface (60) of the cathode current collector. A diffusion member (36) of the cathode assembly (26) is preferably compressed as a seal, at the bottom of the cell (10), between an outer side wall (39) of the cell and the remainder of the cathode assembly (26). The diffusion member (36) is also used at least as an assist in sealing the cell (10) against electrolyte leakage from the anode cavity (137) and past the cathode assembly (26).
The tubular cathode current collector (32) has novel border regions (42, 44, 46, 48), novel longitudinal joint structure (54), novel perforations (56), and including novel methods of making such cathode current collectors (32) and such cells (10).

摘要： The invention relates to seals, and electrochemical cells made therewith. An elongate, generally tubular, air depolarized electrochemical cell (10) comprising a cathode (14), including an air cathode assembly (26), extending about the tubular circumference, and along the tubular length, of the cell (10), an anode (12), a separator (16) between the anode (12) and the cathode (14), electrolyte, a top closure member (177, 200), and a bottom closure member (114, 202). The cathode assembly (26) is fixedly held, by a friction fit, in a slot (116) at the bottom of the cell. The slot can be developed, for example, by inner (110) and outer (114) walls of a cathode can (28), by inner (226) and outer (224) walls of a bottom closure member (202), or by an outer wall (114) of a cathode can (28) and an opposing outer wall of a plug (128) on the interior of the cell. Preferably, bottom closure structure of the cell (10) and receives a bottom edge portion (44) of the cathode current collector (32), and makes electrical contact with the bottom edge portion (44), preferably at an inner surface (60) of the cathode current collector. A diffusion member (36) of the cathode assembly (26) is preferably compressed as a seal, at the bottom of the cell (10), between an outer side wall (39) of the cell and the remainder of the cathode assembly (26). The diffusion member (36) is also used at least as an assist in sealing the cell (10) against electrolyte leakage from the anode cavity (137) and past the cathode assembly (26).
A grommet (18) closes the top of the cell (10). A seal (36) can extend upwardly into a slot (174) between the grommet (18) and a top closure member (177) such as at the top of a cathode can (28), or a separate top closure member (200). Cathode assembly (26) and separator (16) can extend into the slot (174). The seal is between the grommet (18) and cathode assembly (26), or between grommet (18) and separator (16), or both. The seal can extend upwardly into the slot (174) from an outer surface of the cathode assembly (26), can extend about respective upper edges of the cathode current collector (57), catalyst, and separator (16), and downwardly toward, preferably against or along the inner surface of, the separator (16). The top closure member (200) can be crimped against the grommet (18) at the slot (174), with the cathode assembly (26), and optionally the separator (16), in the slot (174) between the grommet (18) and the top closure (200), thus to provide a liquid-tight crimp seal. The top closure (200) can be crimped first against the grommet (18) at the slot (174), and further crimped against the grommet (18) at a second locus (178) displaced longitudinally from the first crimp. Composition of the seal comprises a microporous polymer (36), preferably polytetrafluoroethylene. Preferred embodiments comprise at least two, preferably at least three, layers of air permeable microporous sheet material, useful for diffusion of air therethrough to the cathode reaction surface (63). The layers are wrapped continuously and without intervening end, to form an outer surface of the cathode assembly (26). Another expression of the invention is a cathode assembly (26), or cathode-separator combination, for use in an elongate air depolarized cell (10). The air permeable sheet material (36), as wrapped about the tubular cathode assembly, is compressed so as to have a compressed thickness less than the uncompressed thickness.

摘要： An elongate, generally tubular, air depolarized electrochemical cell (10) comprising a cathode (14), including an air cathode assembly (26), extending about the tubular circumference, and along the tubular length, of the cell (10), an anode (12), a separator (16) between the anode (12) and the cathode (14), electrolyte, a top closure member (177, 200), and a bottom closure member (114, 202). The cathode assembly (26) is fixedly held, by a friction fit, in a slot (116) at the bottom of the cell. The slot can be developed, for example, by inner (110) and outer (114) walls of a cathode can (28), by inner (226) and outer (224) walls of a bottom closure member (202), or by an outer wall (114) of a cathode can (28) and an opposing outer wall of a plug (128) on the interior of the cell. Preferably, bottom closure structure of the cell (10) and receives a bottom edge portion (44) of the cathode current collector (32), and makes electrical contact with the bottom edge portion (44), preferably at an inner surface (60) of the cathode current collector. A diffusion member (36) of the cathode assembly (26) is preferably compressed as a seal, at the bottom of the cell (10), between an outer side wall (39) of the cell and the remainder of the cathode assembly (26). The diffusion member (36) is also used at least as an assist in sealing the cell (10) against electrolyte leakage from the anode cavity (137) and past the cathode assembly (26). An embodiment may provide a stop ledge (106) in grommet (18j) facing a stop groove (102) in a cathode can (28). The cathode assembly (26) can extend into a slot (174) at an outer edge of the grommet (18). A top grommet 204 can have an upwardly extending leg (210A) overlain by a top closure member (206). The air diffusion member (36) may control the rate of entry of air to the reaction surface, depending on density of the air diffusion member (36), whereby the air diffusion member (36) controls the limiting current of the cell (10). The air cell (10) can be free from adhesive bonding the separator (16) to the cathode assembly (26). The bottom of the cathode current collector (32) may be in a bottom slot (116), in a path of flow of current between a reaction surface and a positive electrode terminal (30). A method of fabricating cells can include crimping a top washer (206) and an outer leg (210C) of a top grommet (18) at the same time, including closing a slot (211).

摘要： A circuit and method for detecting and indicating the state of charge of an electrochemical cell or battery are disclosed. The invention finds particular application in the field of battery chargers for alkaline manganese dioxide cells, but may also be used in other types of chargers and electrochemical cells or batteries. In one preferred feature of the invention, a circuit low-pass filters or time-averages a charge enable control or transistor base drive signal, and provides the filtered or averaged signal as a first input to a comparator. The second input to the comparator is a predetermined reference voltage. When the voltage of the low-pass filtered or time-averaged signal becomes less than the reference voltage, the output of the comparator changes state. The change in state indicates that the cell has attained a full state of charge. Microprocessor means for accomplishing the same state of charge detection function are also disclosed.
