A nonaqueous cell employing a manganese dioxide-containing solid cathode having a minor amount of an alkali metal or an alkaline earth metal additive such as Li 2 SiO 3 , Li 2 B 4 O 7 , Li 2 MoO 4 , Li 3 PO 4 or Li 2 WO 4 to suppress the build-up of internal impedance in the cell during storage and discharge that may occur with electrolyte degradation. |
