1,145,658. Lithium-chlorine cells. GENERAL MOTORS CORP. 29 June, 1967 [27 Oct., 1966], No. 30083/67. Heading H1B. The invention comprises a wick which transports a liquid electric cell reactant from a storage region to the cell and there supports it in a fixed relation to its counterreactant and serves as the reaction site. In the Li/ LiCl/C1 2 cell illustrated in Fig. 1, a pressure vessel 1 houses LiCI and Li storage regions 2 and 3 respectively and cell region 4. Region 2 is lined with ceramic coating 6 and a wick electrode 8 extends from region 3 to cell region 4 where it functions as the anode. The cathode 11 comprises porous graphite affixed to a dense graphite support 10 and is supplied with C1 2 via inlet 14, ports 13 and annular passage 12. Separator 16 is between the electrodes and copper sheath 17 surrounds the cell region and functions as the anode terminal. The cathode terminal is connected to stranded copper conductor 15. When charging regions 3 and 4 are full and region 2 is empty. During discharge Li is withdrawn from 3 and LiCI is collected in regions 2 and 3. The wick 8 may be compressed and sintered randomly oriented metal, e.g. stainless steel, fibres 0À0004-0À01 inch long or a metallized (e.g. with nickel) porous substrate. |
