An Improved Exciting Liquid for Electric Batteries:
Year: 1889

page_text: Date of Application, 3rd June, 1889
Complete Specification Left, 3rd Mar., 1890-Accepted, 3rd May, 1890..
PROVISIONAL SPECIFICATION.
An Improved Exciting Liquid for Electric Batteries:
I, MAX SUSSMANN, of 90, Prinzenstrasse, Berlin, in the Empire of Germany,
Chemist, do hereby declare the nature of this invention to be as follows:-
A well-known exciting liquid for electric batteries consists of a solution of ferric
chloride and water. If this solution is used for zinc-carbon batteries, the action of the
latter, while the zinc is powerfully attacked is very strong but it lasts only a short
time.
This latter defect can be obviated by adding to the solution of ferric chloride, in the
preparation thereof, more or less zinc chloride.
The following proportions of the substances used in the composition of the improved
exciting liquid are stated by way of example.
15 parts of ferric chloride.
2 parts of zinc chloride.
30 parts of water.
The quantitative proportions of these substances can be varied within wide limits,
the main condition being in every case the addition of zinc chloride.
A battery containing an exciting liquid which is composed as above described will
work for about ten hours at a tension of from 2 to 1 volts.
Dated this 3rd day of June 1889.

An Improved Exciting Liquid for Electric Batteries.
I, MAX SUSSMANN of 90 Prinzenstrasse, Berlin, in the Empire of Germany,
Chemist, 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:
A well known exciting liquid for electric batteries consists of a solution of ferric
chloride and water. If this solution is used for zinc carbon batteries the action of
the latter whilst the zinc is powerfully attacked is very strong but it lasts only a short
time.
This latter defect can be obviated by adding to the solution of ferric chloride, in the
preparation thereof, more or less zinc chloride.
The following proportions of the substances used in the composition of the improved
exciting liquid are stated by way of example.
15 parts of ferric chloride.
2 parts of zinc chloride.
30 parts of water.
The quantitative proportions of these substances can be varied within wide limits,
the main condition being in every case the addition of zinc chloride, or the chloride of
that metal of which the electrode consists.
A battery containing an exciting liquid which is composed as above described will
work for about ten hours at a tension of from 2 to 14 volts.

page_text: 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 :-
First. An exciting liquid for electric batteries, consisting of a solution of ferric
chloride to which zinc chloride is added.
Second. The addition of the chloride of that metal of which the electrode consists to
the solution of the ferric chloride.
