IMPROVEMENTS IN THE PREPARATION OR MANUFACTURE OF ELEMENTS FOR PRIMARY ELECTRIC BATTERIES
Year: 1884

page_text: I CHAIMSONOVITZ PROSPER ELIESON of Leytonstone in the County of Essex,
Electrician do hereby declare the nature of my said invention for "IMPROVEMENTS
IN THE PREPARATION OR MANUFACTURE OF ELEMENTS FOR PRIMARY ELECTRIC
BATTERIES" to be as follows:-
My invention relates to improvements in the preparation or manufacture of
elements for primary electric batteries and consists essentially in first impregnating
or charging carbon to be used in such batteries with oxygen and then allowing such
carbon to oxidize before being placed in the battery containing a zinc or other
element and preferably a solution of salammoniac or saline solution or an acid
solution or other electrolyte.
In carrying the said invention into practice I take the plate or other piece of
carbon to be treated and place the same in water or other solution capable of giving
off oxygen. I then pass through such carbon a current of electricity so as to ensure
its being charged with oxygen and when charged to the desired extent I remove
the same from the water or other solution and expose it to the air so that it
becomes oxidized after which it is ready for use in a battery.
By the employment in a battery of carbon thus prepared or manufactured I am
enabled to considerably increase the efficiency of such battery as it does not polarize
and after being in use or becoming exhausted will rapidly recover itself by being
left in an open circuit or such carbon may be readily returned to its original stage
of oxidation by removing it from the battery and leaving it exposed to the air for
a short time prior to replacing it in such battery.
Elements prepared as above described are especially adapted for use in dry or
wet galvanic batteries in which zinc or other suitable plates or elements are
employed and the various elements may be separated from each other when placed
in the battery by porous material such as felt or asbestos or by other suitablą
material.
My improved elements are especially applicable for uso in the batteries of the
Leclanché class, and when used in such batteries will considerably increase the
efficiency and constancy of the same.

I CHAIMSONOVITZ PROSPER ELIESON, of Leytonstone, in the county of Essex,
Electrician, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN THE PREPARATION OR MANUFACTURE OF ELEMENTS FOR PRIMARY ELECTRIC
BATTERIES "and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
-
My invention relates to improvements in the preparation or manufacture of
elements for primary electric batteries, and consists essentially in first impregnating
or charging carbon to be used in such batteries with oxygen, and then allowing
such carbon to oxidize before being placed in the battery containing a zinc or other
element and preferably a solution of sal-ammoniac or saline solution or an acid
solution or other electrolyte.
In carrying the said invention into practice, I take the plate or other piece of
carbon to be treated and place the same in water or other solution capable of giving
off oxygen; I then pass through such carbon a current of electricity so as to insure
its being charged with oxygen and, when charged to the desired extent, I remove
the same from the water or other solution and expose it to the air, so that it
becomes thoroughly oxidized after which it is ready for use in a battery.
By the employment in a battery of carbon so prepared or manufactured I am
enabled to considerably increase the efficiency of such battery, as it does not
polarize rapidly and, after being in use or. becoming exhausted, it can be rapidly
restored to its original state of oxidation by being left in an open circuit, or such
carbon may be readily rostored to its original stage of oxidation by removing it
from the battery and leaving it exposed to the air for a short time prior to
replacing it in such battery.
My improved elements prepared as above described are especially applicable for
use in the batteries of the Leclanché class and, when used in such batteries, will
considerably increase the efficiency and constancy of the same.
My improved elements are also well adapted for use in dry or wet galvanic
batteries in which zinc or other suitable plates or elements are employed, and the
various elements may be separated from each other, when placed in the battery, by
porous material such as felt or asbestos or by other suitable material.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The manufacture and use of the improved elements for primary electric batteries
in the manner substantially as herein before described.
