Improvements in Secondary Batteries or Electric Accumulators.
I, JOHN IRVING COURTENAY, of 4, Great Winchester Street, in the City of
London, Gentleman, do hereby declare the nature of this invention (which has
been communicated to me from abroad by Camille Alphonse Faure, of
116, Boulevard Richard-Lenoir, Paris, in the Republic of France, Engineer.) to
be as follows; →
This invention has for its object to provide a secondary battery or electric
accumulator plate, or element, in which the active material, or material to be
rendered active is securely held in place and which is very efficient in action.
According to this invention the grid or support for the active material, or
material to be rendered active, is made of two plates or side pieces parallel
with each other and having portions struck therefrom so that they are severed
from the plate except at one side so that the said portions can be turned inwards
leaving openings for the exposure of the active material, or material to be
rendered active, to the electrolyte, the turned in parts projecting inwards from
the inner sides of each of the plates or side pieces so as to hold the active
material, or material to be rendered active, firmly in position and constitute a
very efficient conductor; the active material, or material to be rendered active,
being placed between the said two plates or side pieces and presenting a surface
to the electrolyte at the said perforations made as aforesaid in the said plates or
side pieces whilst the portions turned in are embedded in the said active material,
or material to be rendered active. The said plates or side pieces may be made
separately and he joined together by soldering or otherwise or they may be
formed in one piece and be bent over so that the one side piece lies parallel with
the other.

Improvements in Secondary Batteries or Electric Accumulators.
I, JOHN IRVING COURTENAY, of 4, Great Winchester Street, in the City of
London, Gentleman, do hereby declare the nature of this invention (which has
been communicated to me from abroad by Camille Alphonse Faure, of
гр

page_text: 116, Boulevard Richard-Lenoir, Paris, in the Republic of France, Engineer),
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
This invention has for its object to provide a secondary battery, or electric
accumulator plate, or element, in which the active material, or material to be
rendered active, is securely held in place, and which is very efficient in action.
According to this invention the grid, or support for the active material, or
material to be rendered active, is made of two. plates, or side pieces, parallel
with each other, and having portions struck therefrom, so that they are severed
from the plate, except at one side, 'so that the said portions can be turned inwards,
leaving openings for the exposure, of the active material, or material to be
rendered active, to the electrolyte, the turned-in parts projecting inwards from
the inner sides of each of the plates, or side pieces, so as to hold the active
material, or material to be rendered active, firmly in position and constitute a
very efficient conductor; the active material, or material to be rendered active,
being placed between the said two plates, or side pieces, and presenting a surface
to the electrolyte at the said openings made as aforesaid in the said plates, or
side pieces; whilst the portions turned in as aforesaid are embedded in the said
active material, or material to be rendered active. The said plates, or side pieces,
may be made separately, and be joined together by soldering, lead burning or
otherwise; or they may be formed in one piece and be bent over so that the one
side piece lies parallel with the other side piece. The accompanying drawing
represents a battery or accumulator plate, or element, made in accordance with
this invention, Figure 1 being a side elevation with one of the side pieces removed
at the upper, part, and with the active material, or material to be rendered; active,
also removed at this part to shew the inside of the other of the side pieces.
Figure 2 is a section on the line 1, 2 Figure 1. A and B are the two side plates
or pieces, of the grid, or support, with portions a and b struck therefrom, and
turned inwards, so as to leave openings at which the active material, or material
to be rendered active, (c), is exposed to the electrolyte, and to act as conductors,
and hold the said material firmly in position. The turned-in edges a² 62 are
soldered or burned together in the arrangement shewn, as the plates A B
are made separately.
-
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
In, or for, secondary batteries, or electric accumulators, plates, or elements,
constructed with grids, or supports, having sides with parts struck therefrom,
and turned inwards; substantially as, and for the purposes, hereinbefore
described..
