Abstract: A fabric separator (10) woven from synthetic halogenated polymeric fibers for use in an electrochemical cell (18) comprising a Group IA, IIA and IIIB metal anode (12) and a depolarizer/catholyte or a solid cathode/electrolyte system (14), is described. The separator (10) is resistant to the highly oxidizing components present in the cell, is tear-resistant and has a reduced thickness to minimize the diminishing effect of the separator on the volumetric amount of active components in the cell. The separator can be used by itself or as a laminate with a microporous film, preferably made of a fluoropolymer fiber.

Abstract: A cell (110) construction that makes use of unbalanced electrode components or portions (128 and 130) comprising one of the electrodes of an electrochemical cell to provide an end-of-life indication, is described. The unbalanced electrode components (128 and 130) can have dissimilar physical dimensions or dissimilar percent loading of electrode active material. This renders the one dissimilar electrode component having the lesser physical dimension, i.e., lesser surface area or thickness (128) or lesser quantity of electrode active material electrochemically unreactive prior to the other electrode component during the course of cell discharge. Upon the early exhaustion or unreactiveness of the one dissimilar electrode component (128), the total cell interelectrode working capacity is reduced by a predetermined factor. The remaining functional electrode component (130) provides the cell with sufficient capacity for electrical discharge at a predetermined lower energy level.

Abstract: A method for manufacturing electrochemical cells having a low electrochemical surface from standard electrodes used in cells having a high electrochemical surface, includes configuring the standard electrodes by folding one or more of the standard electrodes to reduce the overall length, and hence the electrochemical surface area to a fraction of that of the unfolded standard electrode. A cell stack is assembled by placing the folded electrode and a standard electrode, or alternatively a folded cathode (21) and a folded anode (17), in a face-to-face relationship with a separator (25) therebetween.

Abstract: A new process for manufacturing a cathode component from a free-standing sheet of cathode material, is described. The process comprises a first step of adjusting the particle size of the cathode active material (42) to a useful size followed by mixing with a binder and conductive additives suspended in a solvent to form a paste (44). The paste is then fed into a series of roll mills (48) to form the sheet material or the paste can first be pelletized before the rolling step (46). The cathode sheet material is dried (52) and punched (56) into cathode plates having a myriad of geometric shapes suitable for cathode preparation by compressing a current collector between two plates of the cathode material (62).
