LiSO2 +2.9V
(Sulfur Dioxide)

Introduction
Lithium-Sulfur Dioxide batteries have a metallic lithium anode (the lightest of all the metals) and a liquid cathode comprising a porous carbon current collector filled with a sulfur dioxide (SO2) solution. They deliver a voltage of 2.9 V and are cylindrical in several different shapes. Lithium-sulfur dioxide cells have a high energy density and a good capability for delivering repeated bursts of high power. This capability derives from the spiral construction and is utilized in most of the applications addressed by this type of cell.
This kind of cell is mainly used in defense applications, though civil applications also exist.
