Abstract
Abstract The invention relates to a cylindrical type cell employing an outer cathode or cathode collector, a separator and an inner disposed anode in the form of at least two discrete bodies, said anode bodies having centrally disposed biasing means for continuously exerting an outward force against said anode bodies so as to provide good physical contact between the anode-separator-cathode or cathode collector interfaces.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
65 words
An electrochemical cell comprising a container; a solid active reducible cathode disposed within said container; a porous separator disposed within and in surface contact with said cathode; an anode in the form of at least two rectangular bodies disposed within said separator; means for biasing said anode bodies against said separator which, in turn, contacts the cathode; and an electrolyte solution disposed within said container.
Claim 2
Dependent Claim
65 words
An electrochemical cell comprising a container; a solid active reducible cathode disposed within said container; a porous separator disposed within and in surface contact with said cathode; an anode in the form of at least two rectangular bodies disposed within said separator; means for biasing said anode bodies against said separator which, in turn, contacts the cathode; and an electrolyte solution disposed within said container.
Claim 3
Dependent Claim
31 words
The cell of claim 1 wherein the means for biasing the bodies of the anode is a substantially U-shaped spring member in physical contact with and disposed between said anode bodies.
Claim 4
Dependent Claim
27 words
The cell of claim 1 wherein the means for biasing the anode bodies is conductive and is adapted for securing to a negative terminal of the cell.
Claim 5
Dependent Claim
43 words
The cell of claim 1 wherein the cathode comprises two substantially semi-cylindrical cathodes each having a groove imparted in its curved outer surface that faces the internal wall of the container so as to provide an opening for the electrolyte of the cell.
Claim 6
Dependent Claim
31 words
The cell of claim 4 wherein the means for biasing the bodies of the anode is a substantially U-shaped spring member in physical contact with and disposed between said anode bodies.
Claim 7
Dependent Claim
27 words
The cell of claim 4 wherein the means for biasing the anode bodies is conductive and is adapted for securing to a negative terminal of the cell.
