Abstract: A current collector assembly for an electrochemical cell is made by inserting an elongated current collector with identically shaped ends, such as a rod, into a seal body such that a minor amount of the current collector passes through the seal body.

Abstract: A battery is provided with an end-of-cell voltage indicating device which can be used to indicate the state-of-charge of the battery. The indicating device has a flexible substrate of the same peripheral configuration as the battery. The substrate has an indicating coating on one surface which is in thermal or electrical contact with a conductive circuit pattern which can be temporarily connected between the terminals of the battery on application of pressure to an indicated spot on the surface of the substrate. The conductive circuit means causes the indicating coating to undergo a visible change which is representative of the state-of-charge or voltage of the battery. A dual end-switched, integral battery and state-of-charge indicating device having two switches disposed on one end of the battery is also disclosed.

Abstract: An electrochemical cell has bulge responsive means and a wrap disposed about the cell container, wherein the wrap has two separable sections, with one section secured to the container and the other section in coactive engagement with the bulge responsive means. Upon effective bulging of the cell, the one section of the wrap is noticeably separated from the second section of the wrap.

Abstract: Batteries have labels that are comprised of a tester for the battery.

Abstract: Batteries of this invention prevent the flow of electrical current between a reversed cell and an adjacent cell aligned in an end-to-end configuration. Terminals useful with batteries of this invention are characterized by an electrically nonconductive portion cooperatively positioned above an electrically conductive portion. In one embodiment, the terminal's electrically nonconductive portion is masked with an electrically nonconductive resin.

Abstract: An electrochemical cell, such as an alkaline cell, employing a multi-strip separator formed into a closed end cylindrical configuration and where an electrically insulating barrier, such as a plastic film, is disposed at the bottom surface of the separator to prevent electrical shorting between the electrodes of the cell at this location.

Abstract: The invention relates to a galvanic cell having a failsafe circuit interrupter means for electrically isolating one cover terminal of the cell from the cell's electrochemical system when the closed end of the container of the cell bulges beyond a predetermined amount.

Abstract: The invention relates to a galvanic cell having a failsafe circuit interrupter means for electrically isolating one cover terminal of the cell from the cell's electrochemical system in which the closed end of the container is modified so that the closed end of the container can bulge beyond a predetermined amount in response to internal pressure buildup.

Abstract: The invention relates to a cylindrical galvanic cell having a failsafe circuit interrupter means for electrically isolating one terminal of the cells from the cell electrochemical system when the bottom of the cylindrical cell bulges beyond a predetermined amount.
