IMPROVEMENTS IN SECONDARY BATTERIES
Year: 1884

page_text: We ALFRED TRIBE Professor of Chemistry of Denbigh Road Notting Hill in the
County of Middlesex and ASTLEY PASTON PRICE of 47 Lincoln's Inn Fields in the
County of Middlesex Gentleman do hereby declare the nature of our said Invention
for "IMPROVEMENTS IN SECONDARY BATTERIES" to be as follows:-
This Invention relates to Improvements in Secondary Batteries and consists in
the employment for the production of the foundation plates frames, leads or
supports of or for the positive element employed in such batteries of Lead which
has been to a greater or less degree converted into sulphides arsenides or phosphides
that is to say either converted entirely or superficially. Plates frames leads or
supports so prepared are employed as foundation plates frames leads or supports
for the positive elements in secondary batteries.
In carrying out this part of our Invention we employ by preference lead more or
less converted into sulphide arsenide or Phosphide by one or other of the following
processes but other methods may be employed.
The lead may either be brought into contact with molten sulphur and be heated
to a point below the melting point of lead. Or the lead may be converted super-
ficially into sulphide by the employment of a solution of sulphur and the subsequent
application of heat in order that the desired superficial sulphurization may be
effected. Or the lead may be heated in the vapour of sulphur or of Phosphorous
or of arsenic until its surface is converted into lead sulphide into Lead Phosphide
or arsenide or other methods of conversion may be adopted the object of each and
of all of these operations being to convert the surface of the lead into sulphide or into
lead Phosphide or Lead Arsenide.
Or the lead may be melted with sulphur phosphors or arsenic or mixtures of the
same or molten sulphide of lead may be employed and the product or products
thus obtained may be cast into the desired form or forms so as to constitute the
before mentioned Plates frames leads or supports. The foundation plates leads
frames or supports thus obtained may if necessary be further treated by any of
the preceding methods or otherwise in order to further convert their surfaces
into sulphides arsenides or Phosphides and thus still more thoroughly to ensure
if necessary the conversion of the external surface or surfaces into sulphides
phosphides arsenides or mixtures or compounds of the same.

page_text: In order to employ the before mentioned plates leads or frames or supports as
plates frames leads or supports for the positive element or element of secondary
batteries we place thereon or place therein or upon or in contact with the before
mentioned plates frames leads or supports salts or compounds of lead which are
eapable of being reduced and converted into metallic lead by electrolytic action
auch salts or compounds of lead existing for example as minium or other oxides of
lead or salts of lead or compounds of lead. The same having been reduced are
then capable of being employed for the purposes herein before mentioned.

page_text: We, ALFRED TRIBE of Denbigh Road Notting Hill in the County of Middlesex
professor of Chemistry and ASTLEY PASTON PRICE of 47 Lincoln's Inn Fields in
the County of Middlesex, Gentleman do hereby declare the nature of this invention
for "IMPROVEMENTS IN SECONDARY BATTERIES" and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:—
"
This Invention relates to improvements in Secondary Batteries and consists in
the employment for the production of the foundation plates frames supports or
'leads" (any or all of them) of or for the positive element employed in such
Batteries of Lead which has been to a greater or less degree or entirely or super-
ficially converted into sulphides arsenides or phosphides of lead-plates frames
supports or "leads" so prepared are employed as the foundation plates frames
supports or "leads" for the positive element or elements in Secondary Batteries.
In carrying out our Invention we employ by preference lead more or less
converted into sulphide arsenide or phosphide by one or other of the following
processes but any other suitable methods may be employed which will affect the
said conversion.
The lead may be brought into contact with molten sulphur and be, heated to a
point below the melting point of lead. Or the lead may be converted superficially into
sulphide by the employment of a solution of sulphur and the subsequent application
of heat in order that the desired superficial sulphurization may be effected, or the
lead may be heated in the vapour of sulphur or of phosphorous or of arsenic until
the sulphur is converted into lead sulphide, into lead phosphide or into lead
arsenide, or other methods of conversion may be adopted, the object of each and of
all of these operations being to convert the surface of the lead into lead sulphide
or into Lead-phosphide or into Lead Arsenide. Or the lead may be melted with
sulphur phosphorous or arsenic or mixtures of the same, or molten sulphide of
lead may be employed and the product or products thus obtained may be cast into
the desired form or forms so as to constitute the before mentioned plates frames
supports or "leads," which may if necessary be further treated by any of the
preceding methods or otherwise in order to further convert their surfaces into
Sulphides Arsenides or phosphides of lead and thus still more thoroughly to ensure
if necessary the conversion of the external surface or surfaces into Sulphides,
phosphides, Arsenides of lead, or mixtures or compounds of the same.
"
In order to employ the before mentioned plates frames "leads or supports as
plates frames "leads" or supports for the positive element or elements of secondary
Batteries, we place thereon or place therein or upon or in contact with the before
mentioned plates frames "leads" or supports, salts or compounds of lead which are
capable of being reduced and converted into metallic lead by electrolytic action,
such salts or compounds of lead existing for example as minium or other oxides of
lead or salts of lead or compounds of lead. The same having been reduced are then
capable of being employed for the purposes of the battery.

page_text: 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 employment in Secondary Batteries as foundation plates frames supports
and "leads "of or for the positive element of the said Batteries, of lead either
entirely or partially converted into lead-Salphide, lead-phosphide, or lead-arsenide,
substantially as herein before described.
