A Introduction of Lithium Sulfur Dioxide Battery

From:CTECHI GROUP Limited     Release time:2018-09-25

Overview: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.

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.

Specific energy: approximately 250 Wh/kg

Energy density: approximately 400 Wh/L

Specific power: 15 W/kg (light loads)

Discharge efficiency: approx. 50-72%

Energy/consumer-price: 0.12 Wh/dollar

Service or shelf life: 10 years

Self-discharge: 0.25%/month

Cycle durability: primary battery/NA

Nominal cell voltage: 2.85 V (3.9 V with bromine monochloride added)

Open-circuit voltage: 3.0 V (varies by manufacturer)

Cut-off voltage: 2.0 V (varies by manufacturer and use)

Temperature: -55 to +70°C ( the spiral construction and is applied to most of the applications addressed by this type of battery.

This kind of battery is mainly used in military applications, though civil applications also exist.
