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 material which is capable of reducing the mobile oxidant. The electrolyte contains dispersed therein a material capable of reacting with the mobile oxidant preventing it from reaching the anode. For example, silver can be dispersed in the electrolyte of the cell containing mobile iodine in the cathode such that AgI will be formed dispersed throughout the electrolyte during storage.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
19 words
The cell of claim 1 wherein: said material capable of reacting with said oxidant is dispersed in said electrolyte.
Claim 2
Dependent Claim
26 words
The cell of claim 2 wherein the amount of said material capable of reacting with said oxidant is greater adjacent said anode than adjacent said cathode.
Claim 3
Dependent Claim
50 words
The cell of claim 3 wherein said electrolyte has two discrete layers, with a first layer adjacent said cathode containing no material capable of reacting with the mobile oxidant and a second layer disposed between said first layer and said anode containing said material capable of reacting with the oxidant.
Claim 4
Dependent Claim
34 words
The cell of claim 1 wherein said material capable of reacting with said oxidant is selected from the group consisting of reductants for the oxidant and materials which will form complexes with the oxidant.
Claim 5
Dependent Claim
11 words
The cell of claim 1 wherein the mobile oxidant is iodine.
Claim 6
Dependent Claim
35 words
The cell of claim 6 wherein said material capable of reacting with iodine is selected from the group consisting of reductants for iodine, iodide complexes, and charge transfer complexes capable of reacting with the iodine.
Claim 7
Dependent Claim
26 words
The cell of claim 7 wherein said reductant is silver, said silver being present in an amount insufficient to provide an electronic path through said electrolyte.
Claim 8
Dependent Claim
16 words
The cell of claim 8 wherein said silver is in particulate form dispersed throughout said electrolyte.
Claim 9
Dependent Claim
19 words
The cell of claim 8 wherein there is greater concentration of silver adjacent the anode than adjacent the cathode.
Claim 10
Dependent Claim
59 words
The cell of claim 1 in which the electrolyte element comprises an ionically conductive composition of matter wherein the conductivity imparting component has the formula MAg4I5 where M is selected from the group consisting of K, Rb, NH4, Cs and combinations thereof and QAgnIn 1; n varying from 3 to 39 and Q being an organic ammonium iodide cation.
