Abstract :
The authors designed a lithium/thionyl chloride D cell for efficient performance at the moderate rate of ~500 mA (6.25 Ω load). The SNL-MR-D cell has 345 cm2 of active electrode area, 1.0 M LiAlCl4 electrolyte that may have SO2 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°C and 6.25 Ω has been 14.9 Ah (50 Wh). The authors aged the cells at 30°C and 50°C, and measured complex impedance and microcalorimetry during the aging period. The cells have been discharged after the aging period at 25°C and 0°C. This preliminary study established an initial cell design and estimated the rate of capacity loss in storage or in long-term usage
