Abstract
Abstract A battery cell construction is disclosed which has a cathode structure formed of a compound containing either silver or silver oxide and may include mercury oxide. An anode is formed of a compound containing cadmium and nickel. The nickel can be a sheet or screen formed into a spiral or fibers pressed into a pellet with the cadmium. A separator containing electrolyte material is positioned between the cathode and anode compounds. The separator includes alternate layers of ion exchange membranes of two types to provide minimum migration of silver ions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
43 words
The battery cell construction of claim 1 wherein said insulating ring extends radially inwardly of the inner diameter of said first and second housing portions and wherein the upper portion of said sleeve abuts against the radially inward portion of said insulating ring.
Claim 2
Dependent Claim
36 words
The battery cell construction of claim 1 wherein said sleeve includes a radially inward portion at the end opposite the end engaging said insulating ring, said radially inward portion serving to support said electrolyte absorbing layers.
Claim 3
Dependent Claim
58 words
The battery cell construction of claim 1 wherein said anode composition is formed of a spiral oriented upstanding nickel screen secured to the bottom wall of said second housing portIon and a composition of cadmium and cadmium oxide powders are placed in said second housing portion between the adjacent surfaces of said spiral screen forming the anode thereof.
Claim 4
Dependent Claim
24 words
The battery cell construction of claim 4 further including a solution of 50 percent potassium hydroxide mixed with said cadmium and cadmium oxide powders.
Claim 5
Dependent Claim
36 words
The battery cell construction of claim 1 wherein the electrolyte solution is of a predetermined quantity so that during operation of the battery cell the electrolyte solution will deplete before either the cathode or anode compositions.
Claim 6
Dependent Claim
69 words
The battery cell construction of claim 1 wherein said anode structure is formed of a layer of nickel, a layer of cadmium, and a layer of electrolyte absorbing material rolled together and inserted into said second housing portion to be in contact with the bottom wall thereof and extending upwardly therefrom substantially the entire height of said second housing portion to be in contact with said electrolyte absorbing layers.
Claim 7
Dependent Claim
161 words
A battery cell construction comprising in combination, a housing formed of a cup shaped member having a flat bottom wall and circular side wall, and a radially outwardly extended flange at the upper end thereof, a cathode composition positioned within said housing and in contact with said bottom wall, said cathode composition including silver, a cylindrical sleeve positioned within said housing and in contact with the circular wall thereof, said cylindrical sleeve extending between said cathode composition and the upper end of said housing, a ring positioned inwardly of said sleeve and having an outer diameter slightly greater than the inner diameter of said sleeve forming an interference fit therewith thereby creating a seal between said sleeve and said circular wall, electrolyte means positioned within said sleeve and adjacent said ring in contact with said cathode composition, and an anode composition extending into said housing and in contact with said electrolyte means, said anode composition being formed of cadmium and nickel.
Claim 8
Dependent Claim
34 words
The battery cell construction of claim 8 further including an anode cover plate electrically connected to said anode composition and having a peripheral portion sealed and secured to the radial flange of said housing.
Claim 9
Dependent Claim
46 words
The battery cell construction of claim 9 wherein said anode composition is formed of cadmium oxide and nickel fiber and wherein said cover plate is formed of nickel and further including a nickel wire passing through said anode composition and electrically secured to said cover plate.
Claim 10
Dependent Claim
28 words
The battery cell construction of claim 8 wherein said cathode composition is formed of mercury oxide and includes silver in an amount of between 5 and 95 percent.
Claim 11
Dependent Claim
31 words
The battery cell construction of claim 8 wherein said cathode composition is formed of mercury oxide and includes silver oxide in an amount of between 5 and 95 percent by weight.
