The Lithium Sulfur Dioxide Battery or LiSO2 battery

This battery technology is constructed with sulfur dioxide on carbon bonded with Teflon, and is known for its wide operating temperature range, flat voltage-discharge curve, and high energy density. However, every coin has two sides. Because the SO2 is at high pressure, which requires a safety vent, so there is an explosion hazard, and this is a high-cost battery. In addition, the forms of this battery that contain acetonitrile can generate small amounts of very poisonous hydrogen cyanide when working under extreme temperatures.

Another consideration: Especially after long storage or being exposed to low temperatures, the terminal voltage may drop suddenly at the first application of a load and then recover. The effect is similar to lithium thionyl chloride battery chemistries.
