Development of a moderate rate lithium/thionyl-chloride D'' cell
We have designed a lithium/thionyl chloride D'' cell for efficient performance at the moderate rate of {approximately}500 mA (6.25 {Omega} load). The SNL-MR-D cell has 345 cm{sup 2} of active electrode area, 1.0 M LiAlCl{sub 4} electrolyte that may have SO{sub 2} additive, and a cathode blended of Shawinigan Acetylene Black, Cabot Black Pearls 2000, and Teflon binder. The average performance of cells built in-house and discharged at 25{degree}C and 6.25 {Omega} has been 14.9 Ah (50 Wh). We have aged the cells at 30{degree}C and 50{degree}C, and measured complex impedance and microcalorimetry during the aging period. The cells have been discharged after the aging period at 25{degree}C and 0{degree}C. This preliminary study has allowed us to establish an initial cell design and estimate the rate of capacity loss on storage or long-term usage. 13 refs., 6 figs.
