    摘要： A current interrupt assembly for electrochemical cells is disclosed. The current interrupter assembly may be a self-contained, sealed unit which may be separately inserted into the cell during cell construction. Several current interrupt assemblies may be inserted in the cell. The current interrupter assembly has particular utility for thin rechargeable cells and when inserted in the cell forms a portion of the electrical pathway between a cell electrode and corresponding terminal. The current interrupt mechanism comprises a thin thermally responsive member preferably comprising a disk of a shape memory metal alloy having a curved surface. The current interrupt mechanism may include a heat producing electrical resistance means, preferably a Zener diode in proximity to the thermally responsive member. When cell temperature exceeds a predetermined value the disk deflects to cause a break in the electrical pathway within the assembly. The assembly may include therein a flexible electrically conductive member which forms a part of the electrical pathway within the assembly and which is physically responsive to deflection of the thermally responsive member. The assembly may also include a pressure actuated diaphragm which may form a portion of the assembly housing. When the cell internal pressure exceeds a predetermined level the diaphragm deflects causing a break in the electrical pathway within the assembly, thereby shutting down the cell.

    摘要： A primary cell having an anode comprising lithium or lithium alloy and a cathode comprising iron disulfide (FeS2) or a mixture of iron disulfide (FeS2) and iron sulfide (FeS) and conductive carbon particles. A cathode slurry is prepared comprising the FeS2 or FeS2 plus FeS powder, conductive carbon, binder, and a solvent. The binder is preferably a styrene-ethylene/butylene-styrene (SEBS) block copolymer. There is an advantage discovered in utilizing a hydronaphthalene solvent to form the cathode slurry. The preferred solvent is 1,2,3,4-tetrahydronaphthalene or decahydronaphthalene and mixtures thereof. The slurry mixture is coated onto a conductive substrate and the solvent evaporated leaving a dry cathode coating on the substrate. Higher drying temperature may be used resulting in a dry cathode coating which resists cracking. The anode and cathode can be spirally wound with separator therebetween and inserted into the cell casing with electrolyte then added.
