PROVISIONAL SPECIFICATION.
Improvements in Secondary or Storage Batteries.
We, LUIS FALERO, Electro Chemist, of 100 Fellows Road, Hampstead, and
HENRY LUMLEY, Auctioneer, of 22 St. James' Street, both in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
The object of this invention by Luis Falero is to combine durability with
lightness and capacity.
Each plate of the battery consists of a receptacle or vessel of aluminium gauze
or tulle having a central metallic conductor (preferably a sheet of aluminium gauze
or tulle, or perforated or moulded metal, aluminium or its alloys) and filled with
litharge.
In making the plates the litharge is put into the receptacle as paste the central
conductor being held in position. The whole is then passed through rolls which
squeeze it to the thickness desired and at the same time force the litharge into the
interstices of the gauze. The plate is then allowed to dry and the superfluous
litharge is removed.

COMPLETE SPECIFICATION.
Improvements in Secondary or Storage Batteries.
We, LUIS FALERO, Electro Chemist, of 100 Fellows Road, Hampstead, and
HENRY LUMLEY, Auctioneer, of 22 St. James' Street, both in the County of
Middlesex, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying drawings and to
the letters and figures marked thereon, that is to say :-
This invention, which has been devised by Luis Falero, relates to improvements
in secondary or storage batteries, and is designed to obtain greater specific capacity,
and to dispense with the usual heavy lead or antimoniated grids or supports which
have only low electrical conductivity, thus providing a battery which shall combine
very great efficiency and durability with extreme lightness, and, at the same time,
increasing the conductivity of the active material.
According to the invention, each plate or electrode of the battery consists of
aluminium gauze or tulle (or its alloys) or of a perforated sheet of aluminium
(or its alloys) forming, so to speak, a receptacle or vessel, and of a central metallic
conductor, which latter may be of the same materials, or may be moulded in any
desired form, the whole being charged with the active material, for instance,
litharge.
And in order that the invention may be readily understood, we will describe the
same fully with reference to the accompanying drawings, in which :
Fig. 1 is a side view of a plate or electrode, such as referred to, certain of the
parts being broken away for the sake of clearness.
Fig. 2 is a vertical section thereof.

page_text: Figs. 3 and 4 are corresponding views to Figs. 1 and 2, shewing a slightly
modified construction.
Fig. 5 shews an arrangement wherein several internal.conductors are provided.
Referring to Figs. 1 and 2, a represents the outer aluminium gauze or tulle
which is provided on each side of the electrode, and serves as a protection against
disintegration. It consists, in the present instance, of a single sheet so bent or
folded as to form, as it were, the receptacle or vessel. is the central metallic
conductor which, in this case, consists of a sheet of perforated aluminium, and
which is placed in electrical communication with the outer gauze or tulle, by
a cap c, or by any other suitable means. d represents the active material.
In making the plates or electrodes the litharge is put into the receptacle a as
a paste, the central conductor b being placed inside. The whole is then rolled,
pressed, or squeezed, in any suitable way, to bring it to the thickness desired and,
at the same time, to force the litharge into the interstices of the gauze.
The plate is then allowed to dry, and the superfluous litharge is removed.
In the modified construction shewn in Figs. 3 and 4, perforated aluminium
sheets a, or plates cast with the required perforations are employed instead of
aluminium gauze or tulle, and the central conductor b is formed of aluminium
gauze or net, the construction and mode of manufacture being, in other respects,
the same as in the first mentioned arrangement.
Obviously, however, the plates or electrodes may be made with aluminium gauze
or perforated aluminium sheet, both inside and outside; and instead of a single
central conductor several such conductors may be arranged side by side with active
material between them, as indicated in Fig. 5.
In constructing a storage battery of electrodes made according to this invention,
the said electrodes may be arranged vertically side by side, in the ordinary
manner; or they may be arranged horizontally one above the other, with distance
pieces of insulating material between them; or they may be rolled up into spiral
form, or be arranged concentrically one within the other, or may be fluted, folded,
tubular, or otherwise.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same may be performed we declare that what we
claim is:
1. A secondary or storage battery having its electrodes formed of aluminium
gauze or tulle, or of perforated sheets of aluminium, or its alloys, and charged with
active material, substantially as and for the purposes described.
2. A secondary or storage battery having electrodes consisting of an outer
receptacle of aluminium, or its alloys, in the form of gauze, tulle, or perforated
sheets, charged with active material, and provided with one or more internal
conductors, also of aluminium, or its alloys, either moulded or in any of the above
forms, substantially as described.
3. The special construction of aluminium electrode, for secondary or storage
batteries, as described with reference to Figs. 1 and 2 of the annexed drawings.
4. The special construction of aluminium electrode, for secondary or storage
batteries, as described with reference to Figs. 3 and 4 of the annexed drawings.
5. The special construction of aluminium electrode, for secondary or storage
batteries, as described with reference to Fig. 5 of the annexed drawings.
6. The manufacture and use of our improved aluminium electrodes for secondary
or storage batteries, substantially as hereinbefore described and as illustrated in the
annexed drawings.
