Lithium Sulfur Dioxide (Li-SO2) Battery delivered a voltage of 2.9V. The batteries have
a high energy density and a good capability for delivering repeated bursts of high power.
This kind of cell is mainly used in defense applications, utility metering and etc.

Key Features:
Wide operating temperature range (-55°C to +65°C)
High operating voltage, stable during most of the application lifetime
High safety: non-flammable (but corrosive) pressurized electrolyte, quickly expelled in case of venting 

Low self discharge: less than 3% capacity loss during storage at ambient temperature before use

Applications:
Alarms and security wireless devices
Mobile asset tracking
Electronic Meters (Water, Gas, Electricity)
Professional electronics
