Abstract
Abstract A solid state electric cell having a mobile oxidant such as iodine in the cathode, a solid state electrolyte and a suitable anode containing a reductant material such as silver which is capable of reducing the mobile oxidant, wherein at least the anode additionally contains a material which is capable of reacting with the primary reaction product of the mobile oxidant and reductant to form a resulting product in situ that has improved ionic conductivity as compared to the primary reaction product.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
20 words
The cell of claim 1 wherein said anode comprises said reductant dispersed in a solid electrolyte having high ionic conductivity.
Claim 2
Dependent Claim
36 words
The cell of claim 2 wherein: the additive material will react with the primary reaction product of the oxidant and reductant to form a product which is the same as the electrolyte present in the anode.
Claim 3
Dependent Claim
38 words
The cell of claim 2 wherein the additive material is selected from the group consisting of MI and M2AgI3 and mixtures thereof where M is selected from the class consisting of K, Rb, NH4, Cs and combinations thereof.
