Abstract
Abstract An improved storage battery which is composed of carbon and zinc plates having separators therebetween, the zinc plates being left untreated while the carbon plates are treated with manganese dioxide. Wherein the plates are pivotally suspended and perforated for better circulation of the electrolyte solution.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
48 words
In a manganese storage battery a battery case divided into a plurality of cells, zinc negative plates and carbon positive plates with separators therbetween being in each said cell, said plates being connected electrically to exterior battery terminal posts, and an electrolyte comprised of manganous hydroxide and water.
Claim 2
Dependent Claim
48 words
In a manganese storage battery a battery case divided into a plurality of cells, zinc negative plates and carbon positive plates with separators therbetween being in each said cell, said plates being connected electrically to exterior battery terminal posts, and an electrolyte comprised of manganous hydroxide and water.
Claim 3
Dependent Claim
25 words
The combination as set forth in claim 1 wherein, when battery is charged, a manganese dioxide from said electrolyte is deposited on said carbon plates.
Claim 4
Dependent Claim
36 words
The combination as set forth in claim 2 wherein means are provided for permitting electrodes to move relative to the walls of the battery responsive to inertial forces such as change of vehicle speed or vibrations.
Claim 5
Dependent Claim
42 words
The combination as set forth in claim 3 wherein further means are provided for causing the displacement of adjacent electrodes to be unequal so that in the process the distance between adjacent electrodes transitionally varies causing the electrolite to be forcefully moved.
Claim 6
Dependent Claim
17 words
The combination as set forth in claim 2 wherein the electrodes have holes to improve electrolyte circulation.
Claim 7
Dependent Claim
20 words
The combination of claim 5 wherein the holes are at an acute angle to the surface of the electrode plate.
Claim 8
Dependent Claim
15 words
The combination of claim 6 wherein the cross sectional shape of the holes is conical.
Claim 9
Dependent Claim
42 words
The combination as set forth in claim 4 wherein one of the means for permitting electrodes to move is a pivoted suspension arm into which the two groups of electrodes are hinged at unequal distances from the pivot point of said arm.
Claim 10
Dependent Claim
34 words
The combination as set forth in claim 5 wherein means for limiting the initial displacement of said hinged electrodes are provided, which means also serve the elastic conductive connection between electrodes and external terminals.
