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: 9
Claim 1
Independent Claim
69 words
An electrochemical cell comprising a container; a cathode collector disposed within said container; a porous separator disposed within and in surface contact with said cathode collector; an anode in the form of at least two discrete bodies disposed within said separator; means for biasing said anode bodies radially outward against said separator which in turn contacts the cathode collector; and a liquid active reducible cathode-electrolyte disposed within said container.
Claim 2
Dependent Claim
69 words
An electrochemical cell comprising a container; a cathode collector disposed within said container; a porous separator disposed within and in surface contact with said cathode collector; an anode in the form of at least two discrete bodies disposed within said separator; means for biasing said anode bodies radially outward against said separator which in turn contacts the cathode collector; and a liquid active reducible cathode-electrolyte disposed within said container.
Claim 3
Dependent Claim
24 words
The cell of claim 1 wherein the anode is in the form of two arc segments each ranging from about 140° to 180° .
Claim 4
Dependent Claim
23 words
The cell of claim 1 wherein the anode is in the form of three arc segments each ranging from about 90° to 120°.
Claim 5
Dependent Claim
16 words
The cell of claim 1 wherein the anode is in the form of two rectangular members.
Claim 6
Dependent Claim
34 words
The cell of claim 1 wherein the means for biasing the bodies of the anode radially outward is a substantially "U" shaped spring member in physical contact with and disposed between said anode bodies.
Claim 7
Dependent Claim
47 words
The cell of claim 1 wherein the anode bodies are arcuate bodies and wherein the means for biasing the arcuate bodies of the anode radially outward is a generally cylindrical spring member in physical contact with and disposed axially within an opening defined by said arcuate bodies.
Claim 8
Dependent Claim
23 words
The cell of claim 1 wherein the cathode collector comprises two semi-cylindrical members each having a semi-circular longitudinal groove imparted in its circumference.
Claim 9
Dependent Claim
24 words
The cell of claim 1 wherein a backing sheet is disposed in physical contact with the innermost wall of each of the anode bodies.
