  Lithium Sulfur Dioxide Battery  Introduction


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 burst of high power.Those 

batteries are mainly used in defense applications, utility metering and etc.

Key Features:
Wide operating temperature range (-55C to +65C)
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 rate: 
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
