摘要： A primary electrochemical cell having an oxidizable anode, for example lithium, and an electrolytic solution including a reducible liquid cathode material, for example thionyl chloride. An additive material, for example polyvinyl chloride, in the form of a gel of polyvinyl chloride and the reducible liquid cathode material is dispersed throughout the electrolytic solution. When the temperature of the cell rises due to abnormal conditions, such as those present during a short circuit, the additive material dissolves in the solution limiting the current flow within the cell.

摘要： An electrochemical cell having two electrodes of opposite polarity cooperating with an electrolyte solution to produce an electrical potential there between during normal operation, configured to minimize explosions upon forced discharge or charging by locating at least a portion of one electrode in close proximity to the other electrode such that a low impedance path is created between the two electrode surfaces whereby the quantity of externally imposed current flowing through the main body of the cell is minimized. In a preferred embodiment, portions of the two electrodes have contiguous surfaces spaced from each other by a porous separator material with the surfaces chosen to allow plating dendritic growth from one electrode to the other at potential differences below that at which electrolysis occurs.

摘要： A method for assembling a primary electrochemical cell including a carbon cathode structure. The carbon cathode structure is assembled by arranging a selected number of individual annular-shaped porous carbon elements, each having an opening extending therethrough, together with an elongated, hollow, cylindrical metal current collector tube so that the carbon elements are in a stacked array and the tube is loosely disposed within and along the openings in the array of carbon elements. The current collector tube is an expandable member and is initially in a non-expanded state and loosely surrounded by the stacked array of carbon elements. A porous separator and an anode structure are then placed around the aforementioned assembly of the carbon elements and the current collector tube, and the resultant assembly, representing a battery stack, is placed within an elongated housing of an electrochemical cell. A tool is then employed to permanently expand the current collector tube outwardly so that the tube makes direct physical contact with the array of carbon elements. An electrolytic solution is placed within the cell in contact with the battery stack and the hollow opening of the tube. The electrolytic solution permeates the carbon elements directly and also by way of a large number of small holes formed in the tube, causing the porous carbon elements to be permeated with the electrolytic solution and expand outwardly. The expansion of the carbon elements causes constituent particles thereof to fill the openings in the current collector thus thereby permanently locking the carbon elements to the current collector tube.

摘要： A battery includes a negative electrode comprising metallic lithium (Li) in conjunction with lithium chlorate (LiClO.sub.3) electrolyte. Lithium perchlorate (LiClO.sub.4) may also be used as the electrolyte. Lithium chloride (LiCl) and lithium oxide (Li.sub.2 O), individually or together, may also be utilized with lithium chlorate or lithium perchlorate in forming the electrolyte. A positive electrode comprises a metal, such as nickel. In one form, a sheet of lithium metal is sandwiched between two sheets of nickel comprising a negative electrode, one nickel sheet being perforated to permit contact between the lithium sheet and a lithium chlorate electrolyte contained within an insulative member, the other electrode comprising a film of metallic nickel disposed upon the insulative member and in contact with the electrolyte; alternatively, a film or sheet of lithium metal may be disposed upon the insulator as a negative electrode. An additional form includes a ceramic housing comprising a solid ionic conductor and having an interior chamber containing sodium (Na) or lithium as a negative electrode; a liquid electrolyte is disposed within a recess formed by the exterior walls of the housing and a positive electrode in the form of a layer of metallic nickel disposed around the exterior walls of the housing, the electrolyte being in electrical contact with the respective electrodes. A pocket cell form comprises a liquid electrolyte disposed within a recess of a block with the negative electrode inside the recess and the positive electrode in the form of a screen at the mouth of the recess.
