1484237 Lithium-iodine cell WILSON GREATBATCH Ltd and W GREATBATCH 18 Feb 1976 [10 March 1975] 06392/76 Heading H1B A Li-iodine cell comprises a cathode region 34 of iodine-containing material having two major surfaces (upper and lower) and a current collector 36 therein spaced from said surfaces, cathode conductor 18<SP>1</SP> connected to collector 36, a first Li anode element 40 contacting one of said surfaces, a second Li anode 42 contacting the other surface, and anode electrical conductors (not shown) connected to the Li anodes (by collectors 54 and 56). Li anode 40 is held in cup 40, e.g. of fluoropolymer, and covered with organic electron donor layer 50, e.g. of polyvinylpyridine; a similar arrangement 42, 48, 52 exists for anode 42. Member 60 is an insulating separator; this coacts with insulator 62 to insulate conductor 18<SP>1</SP> from Li anodes 40, 42. Two cups 64 and 30 inter-fit as shown to seal the cell; collector 36 may be a Pt mesh and 18 a Pt strip ; 54 and 56 and their conductors 20<SP>1</SP>, 22<SP>1</SP> (Fig. 17, not shown) are of Zr mesh and strip respectively; cathode 34 is a charge-transfer complex of an organic donor and iodine. A battery may be made by putting 2 of the above in series, face to face, in an insulating wrapper filled with potting compound; this may be used to power a cardiac pacemaker. |
