Abstract

Abstract Improved performance of organic electrolyte cells is obtained by dissolving a non-ionic surfactant in the organic electrolyte with the non-ionic surfactant comprising at least 0.01 percent by weight and, preferably, about 0.01 to about 2 percent by weight of the weight of organic electrolyte.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 66 words
AN IMPROVED CURRENT PRODUCING, ORGANIC ELECTROLYTE CELL WHICH COMPRISES AN OPERABLE COMBINATION OF AN ANODE, A CATHODE, AND AN ORGANIC ELECTROLYTE SUBSTANTIALLY FREE OF WATER AND IN WHICH THE IMPROVEMENT COMPRISES A NON-IONIC SURFACETANT WHICH IS SOLUBLE IN SAID ORGANIC ELECTROLYTE AND WHICH IS PRESENT IN SAID CELL IN AN AMOUNT OF AT LEAST ABOUT 0.01 PERCENT BY WEIGHT OF THE WEIGHT OF SAID ORGANIC ELECTROLYTE.
Claim 2
Dependent Claim 66 words
AN IMPROVED CURRENT PRODUCING, ORGANIC ELECTROLYTE CELL WHICH COMPRISES AN OPERABLE COMBINATION OF AN ANODE, A CATHODE, AND AN ORGANIC ELECTROLYTE SUBSTANTIALLY FREE OF WATER AND IN WHICH THE IMPROVEMENT COMPRISES A NON-IONIC SURFACETANT WHICH IS SOLUBLE IN SAID ORGANIC ELECTROLYTE AND WHICH IS PRESENT IN SAID CELL IN AN AMOUNT OF AT LEAST ABOUT 0.01 PERCENT BY WEIGHT OF THE WEIGHT OF SAID ORGANIC ELECTROLYTE.
Claim 3
Dependent Claim 15 words
The cell of claim 1 wherein said non-ionic surfactant is present in said organic electrolyte.
Claim 4
Dependent Claim 26 words

Claim 5
Dependent Claim 33 words
The cell of claim 1 wherein said non-ionic surfactant is present in said cell in an amount between about 0.01 and about 10 percent by weight of the weight of said organic electrolyte.
Claim 6
Dependent Claim 30 words
The cell of claim 1 wherein said non-ionic surfactant is present in an amount between about 0.01 and about 2 percent by weight of the weight of said organic electrolyte.
Claim 7
Dependent Claim 29 words
The cell of claim 1 wherein said non-ionic surfactant is selected from the group consisTing of alkyl aryl polyethers, alkyl aryl polyethylene glycol ethers, and alkyl aryl polyether alcohols.
Claim 8
Dependent Claim 32 words
The cell of claim 6 wherein said non-ionic surfactant is one of nonyl phenoxy polyoxyethylene, nonyl phenyl polyethylene glycol ether, dodecylphenyl polyethylene glycol ether, iso-octyl phenoxy polyexthoxy ethanol and nonylphenoxy polyethoxy ethanol.
Claim 9
Dependent Claim 80 words
An improved current-producing, organic electrolyte cell which comprises an operable combination of (a) an anode of a metal which is less noble than zinc, (b) a cathode comprised of a carbonaceous material, and (c) an organic electrolyte substantially free of water, said improvement comprising: a non-ionic surfactant which is soluble in said organic electrolyte and which is operably present in said cell in an amount of at least about 0.01 percent by weight of the weight of said organic electrolyte.
Claim 10
Dependent Claim 80 words
An improved current-producing, organic electrolyte cell which comprises an operable combination of (a) an anode of a metal which is less noble than zinc, (b) a cathode comprised of a carbonaceous material, and (c) an organic electrolyte substantially free of water, said improvement comprising: a non-ionic surfactant which is soluble in said organic electrolyte and which is operably present in said cell in an amount of at least about 0.01 percent by weight of the weight of said organic electrolyte.
Claim 11
Dependent Claim 43 words
The cell of claim 8 wherein said anode metal is one of sodium and lithium, and said cathode material is a material having the general formula (CFx)n where x is a positive number up to 2 and n is an indefinite, large number.
Claim 12
Dependent Claim 34 words
The cell of claim 9 wherein said non-ionic surfactant is present in said organic electrolyte in an amount between about 0.01 and about 10 percent by weight of the weight of said organic electrolyte.
Claim 13
Dependent Claim 30 words
The cell of claim 9 wherein said non-ionic surfactant is present in an amount between about 0.01 and about 2 percent by weight of the weight of said organic electrolyte.
Claim 14
Dependent Claim 29 words
The cell of claim 9 wherein said non-ionic surfactant is selected from the group consisting of alkyl aryl polyethers, alkyl aryl polyethylene glycol ethers, and alkyl aryl polyether alcohols.
Claim 15

Claim 17
Independent Claim 69 words
A method for improving the performance of a current-producing, organic electrolyte cell having, in operable combination, an anode, a cathode, and an organic electrolyte substantially free of water, said method comprising adding a non-ionic surfactant to said organic electrolyte, said non-ionic surfactant being soluble in said organic electrolyte and being present in an amount of at least about 0.01 percent by weight of the weight of said organic electrolyte.
Claim 18
Dependent Claim 32 words
The method of claim 14 in which said non-ionic surfactant is added in an amount between about 0.01 percent and about 10 percent by weight of the weight of said organic electrolyte.
