Abstract: A lithium electrochemical cell including an anode and cathode assembly with the anode connected electrically to a conductive cell casing and an insulated cathode conductor extending through a lid at an end of the casing and connected to a cathode lead near the lid and with a first insulating component for insulating the casing from cell components therein and extending along and within the casing from a closed end thereof toward the lid, and which is characterized by a second insulating component for insulating the lid from components in the casing and extending along within the lid and toward the first insulating bag so as to prevent a short circuit between the lid or casing and the cathode assembly caused by formation of lithium clusters in the region between the lid or casing and the cathode connector. Preferably the second insulating component is in the form of a cup having a relatively thin base portion extending along the lid and a relatively thin wall portion extending from the base along within the casing and toward the first insulating component which also is in the form of a thin-walled cup. The walls of the first and second insulating components preferably meet in overlapping relation. The insulating arrangement is particularly adapted for use in a cell wherein the anode and cathode assembly comprises a plurality of cathode plates with anode sections interposed therebetween.

Abstract: A combination separator comprising a single layer of a non-woven, polyolefinic cloth superposed with a single layer of a polyolefinic, microporous film for use in an electrochemical cell, is described. A preferred polyolefinic material for both the non-woven cloth and the microporous film is polypropylene. The redundancy of using two layers of separator is an enhanced safety characteristic of the cell; however, the use of the polypropylene web/film combination adds another dimension to the cell's safety characteristics by imparting the benefits of each type of material.

Abstract: A multi-plate wound cell assembly constructed similar to a conventional jellyroll electrode assembly except that each electrode comprises a series of plates spaced along a continuous current collector, and the plates are flat-folded rather than wound into a cylinder, is described. The length of the current collector between adjacent plates of the anode and cathode electrodes increases as the folding progresses to allow for the increase as the electrode assembly is flat-folded.

Abstract: An alkali metal/solid cathode electrochemical cell, particularly a Li/CF.sub.x cell, having an electrolyte-to-cathode (E/C) weight ratio of about 0.94 to 0.96, and an anode-to-cathode (A/C) capacity ratio of about 1.03, is described. These ratios provide the cell with an improvement of about 6.7% in terms of volumetric energy density and about 11.9% in terms of gravimetric energy density over prior art Li/CF.sub.x cells.
