Popis: | The discharge capacity of Li/SO/sub 2/ cells was examined at high current and temperatures. D cells rated at 8 Ah delivered over 7 Ah at 5A current and 55/sup 0/C, while cells discharged at 72/sup 0/C gave 7 Ah at 3A. The cells were analyzed for residual lithium and sulfur dioxide. Spent cathodes were analyzed by infrared spectroscopy. A parasitic reaction was found in which Li/sub 2/S/sub 2/O/sub 6/ and S were formed, presumably by reaction of Li/sub 2/S/sub 2/O/sub 4/ with SO/sub 2/. This reaction became noticeable only under extreme combination of high rate and temperature. |
