Features: 1. High operating voltage 2. Extension of temperature range up to +150. 3. Superior shelf life and high reliability. 4. Smaller in capacity. The Li-SOCl2 battery uses liquid Thionyl Chloride (SOCl2) as its positive active material, and Lithium (Li) as its negative active material. The reactions of the batteries are shown below. Positive reaction: 2SOCl2 + 4Li+ + 4e- ?4LiCl + S + SO2 Negative reaction: Li Li+ + e- Total reaction: 2SOCl2+4Li 4LiCl+ S + SO2
