Abstract: An electrochemical cell is described. The electrochemical cell includes an anode, a cathode, a separator between said anode and said cathode, and an electrolyte. The electrolyte includes a salt dissolved in an organic solvent. The separator in combination with the electrolyte has an area specific resistance less than 2 ohm-cm2. The electrochemical cell has an interfacial anode to cathode ratio of less than about 1.1.

Abstract: Primary lithium cells are provided, the cells having an anode comprising lithium and a cathode comprising iron disulfide. Features of the cells are optimized in order to enhance the cell performance within the constraints imposed by the maximum permitted level of lithium and standard cell dimensions.

Abstract: A primary cell having an anode comprising lithium and a cathode comprising iron disulfide (FeS2) and carbon particles. The electrolyte comprises a lithium salt dissolved in a solvent mixture which contains 1,3-dioxolane and isosorbide dimethyl ether. The solvent mixture may comprise 1,3-dioxolane, 1,2-dimethoxyethane and additive isosorbide dimethyl ether. The isosorbide dimethyl ether comprises typically between about 2 and 15 percent by weight of the solvent mixture and improves cell service life and performance. A cathode slurry is prepared comprising iron disulfide powder, carbon, binder, and a liquid solvent. The mixture is coated onto a conductive substrate and solvent evaporated leaving a dry cathode coating on the substrate. The anode and cathode can be spirally wound with separator therebetween and inserted into the cell casing with electrolyte then added.
