Abstract
The behavior of 
as positive electrode material in organic solvent batteries has been investigated. This oxide in 
solutions shows low solubility and satisfactory polarization behavior. Micropolarization tests showed the reversibility of the redox process of 
in the considered electrolyte. From, the voltage sweep curve a charge‐discharge efficiency of about 100% could be deduced. Discharges at 0.5, 1.0, and 2.0 mA/cm2 of cells 
indicated a good cathodic efficiency if a two‐electron process is hypothesized. 
positive electrodes, showing a lower polarization and supplying more practical specific energy, behave better than analogous 
electrodes in 
.
