Lithium-sulfur dioxide (Li-SO2)
Lithium-sulphur dioxide cells have an anode in metallic lithium (the lightest of the metals) and a liquid cathode comprising a porous carbon current collector filled with a sulphur dioxide (SO2) solution. They deliver a voltage of 2.8 V and are cylindrical in shape, in ½ AA to double-D format, with spiral electrodes.
Lithium-sulphur dioxide cells have a high energy density (250 Wh/kg) and a good aptitude for delivering repeated bursts of high power (up to 400 W/kg), a characteristic that derives from the spiral construction and is put to use in most of the applications addressed by this type of cell.
This kind of cell is mainly used in defence applications, though civil applications also abound.
