PROVISIONAL SPECIFICATION.
Improvements in Secondary Batteries.
I, NICHOLAS WLADIMIROFF, of No. 14, Great Possadskaia Street, St. Peters-
burg, in the Empire of Russia, Lieutenant of the Moscow Guards, Russian Army,
do hereby declare the nature of this invention to be as follows:-
My invention relates to secondary electric batteries and consists chiefly in making
each of the electrodes of the same chemical nature on both sides, so that it acts
simultaneously as a positive pole in one of the cells of the battery, and as a
negative pole in the adjoining cell.
In carrying out my invention I construct the battery of a series of frames of
aunular or other suitable form and of any suitable material which is non-conducting
and unaffected by acids. Between each of the frames is inserted an electrode
consisting of a plate of any desired shape, for instance of circular form, with
concentric grooves on both sides to enable it to better retain the "acting" material.
The two end electrodes rest against two plates of non-conducting material, which
are firmly tied together by bolts. The end electrodes are provided with lugs for
connecting them to terminals. Each of the frames is provided with two apertures
in which are inserted funnel-shaped tubes of glass or other suitable material for
pouring in the acid.
It is obvious that if a current be passed through a battery of this construction
each of the electrodes or plates will form a positive pole on one side and a
negative pole on the other, for instance, if the plates are of lead, peroxyde of lead
will be formed on one side and spongy lead will be reduced on the other.

COMPLETE SPECIFICATION.
Improvements in Secondary Batteries.
1, NICHOLAS WLADIMIROFF, of No. 14, Great Possadskaïa Street, St. Peters-
burg, in the Empire of Russia, Lieutenant of the Moscow Guards, Russian Army,
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:-
My invention relates to secondary electric batteries and consists chiefly in such
an arrangement of electrodes of the same chemical nature on both sides, that each
of them acts simultaneously as a positive pole in one of the cells of the battery,
and as a negative pole in the adjoining cell. It will be understood that my
improved battery can be arranged either vertically or horizontally.
In order to enable the invention to be fully understood I will describe the same
by reference to the accompanying drawing, in which :-
Figure 1 is a side view partly in section of a battery constructed according to my
invention.
Figure 2 is a sectional elevation thereof, and
Figure 3 is an elevation of one of the electrode plates.
a, a represent a series of frames of annular form (but which may be of other
suitable shape) and of any suitable material which is non-conducting and unaffected
by acids. Between each of the frames a, a is inserted an electrode 6 consisting of
a plate of any desired shape for instance of circular form, as shewn in the drawing,

with concentric grooves on both sides to enable it to better retain the "acting"
material. The two end electrodes ', ' rest against two plates c, c of non-conducting
material, which are firmly tied together by bolts d, d. The end electrodes, bare
provided with lugs c¹, c¹ for connecting them to terminals e, e. Each of the frames
is provided with two. apertures in which are inserted funnel-shaped tubes f, f, of
glass or other suitable material for pouring in the acid.
It is obvious that if a current be passed through a battery of this construction
each of the electrodes or plates, will form a positive pole on one side and a
negative pole on the other, for instance, if the plates are of lead, peroxyde of lead
will be formed on one side and spongy lead will be reduced on the other.
The number of electrodes or plates in the battery may vary according to the
required number of volts, and is determined by formula X=0, 55n+1, where :
X is the number of plates and n is the required number of volts. The surface
dimensions of the plates are determined by the number required of ampere hours,
as is well known.
The chief advantages of my improved battery are as follows:-
(a) It occupies very little space and is very economical especially with currents
of great strength.
(b) Its weight is less than that of any other system of secondary batteries of the
same electric energy.
(c) The acting mass is "formed" very easily and quite regularly, because the
current passes practically through the whole surface of each plate at once, and does
not enter from one side only as in existing batteries.
(d) The cells or clements of the battery have no screws or connecting pieces
outside of the battery.
(e) The use of sulphuric acid produces no dirt and no closing of current is caused
by contact pieces which are entirely dispensed with in this battery.
() The battery is easily removed and the liquid is not spilled by the
movement; and further the battery is movable as a whole and need not be taken to
pieces.
(All parts of the battery being firmly connected together the electrodes or
plates do not shrink or become displaced or distorted.
() The battery may remain at rest for long periods without losing its charge.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
A battery or accumulator each of the electrodes or plates of which, being of the
same chemical nature on both sides, acts simultaneously as a positive pole in one of
the cells or elements, and as a negative pole in the adjoining cell or element of the
battery, substantially as herein before described.
