page_text: EDWARD ALEXANDER PARIS, Electrical Engineer, 38, Chestnut Road, West
Norwood, S.E., do hereby declare the nature of this invention to be as follows:-
The object of my invention is to produce an electrode of low resistance to allow
of rapid charging and discharging of secondary batteries or accumulators and
consists essentially of a core of copper sheet, woven copper wire or other high
conducting metal or of rods of such metal. The core of high conducting metal is
so imbedded in the lead plates or cylinders or rod of lead or other materials used
for electrodes of secondary batteries as to be protected against the action of the
electrolyte.
I, EDWARD ALEXANDER PARIS, of 38, Chestnut Road, West Norwood, in the
County of Surrey, Electrical Engineer, 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:.
-
The object of this invention is to produce an electrode of low resistance, to allow
of rapid charging and discharging of secondary batteries or accumulators, while
decreasing the size and weight of the electrode.
It consists essentially of a core of metal of high conductivity embedded in the
plates, cylinders or rods of lead, lead alloy or other metal used for the grids or
other supports for the active material employed in secondary batteries.
When used for plates of the Plante type when the active material is formed out
of the substance of the grid itself, the lead would be cast round the copper or
other high conducting metal, so as to allow sufficient thickness to protect the
copper or other core from the action of the electrolyte. For plates of the Faure
or pasted type, the core, of copper or other high conductivity metal, may be coated
with an unoxidizable lead alloy, a comparatively thin coating being all that is
necessary.
In order that my invention may be more readily understood I have caused to
be attached hereto one sheet of drawings in which similar letters refer to similar
parts.
Fio 1 is an elevation of one of the plates showing various patterns of cells.

page_text: Fig. 2 is a section of a plate.
A is a plate of lead or other suitable material having recesses or cells B formed
on each side, for the purpose of receiving the paste or active material, the said
cells being of any suitable forms some of which are shown in Fig. 1.
The core C, which may consist of sheets, woven wire, or rods, of copper or other
metal of high conducting power embedded in the plate A as shown and is provided
with a suitable projection 1) for connecting up the plates. Holes E may be formed
in the core C so that the lead or other material forming the plate may be run in
and thereby hold the core securely in the plate.
Instead of the flat plates as shown in the drawing, cylinders, rods or blocks of lead
or any other material used for the electrodes of accumulators or secondary batteries
may be employed & the core embedded in them in a similar manner.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, declare that what
I claim is:-
1. In secondary battery plates a core composed of sheets woven wire or rods of
copper or other suitable conducting metal, embedded in the plates, rods or cylinders
of lead or other material, forming the electrode of the cell, as and for the purposes
herein described.
