WILLIAM JOSEPH STARKEY BARBER-STARKEY, Aldenham Park, Bridgnorth, Salop,
Barrister, I do hereby declare the nature of this invention to be as follows:-
My Invention relates to the use of a new Electrolyte in Secondary Cells or
Accumulators, and applies chiefly to those Accumulators which are commonly known
to comprise dilute Sulphuric Acid as the Electrolyte and Lead opposed to Peroxide or
other oxides of Lead, as the Electrodes or Plates. The Electrolyte I employ is a
solution of Bisulphate of Sodium alone, or a mixture of Bi-Sulphate of Sodium and
dilute Sulphuric Acid. Solid Bisulphate of Sodium is in several respects more
convenient and useful than Sulphuric Acid for the purpose under notice, and with its
Solution good Electrolytic results are obtained. When however the positive and
negative plates in an ordinary Secondary Battery or cell are whitened, by a
compound insoluble in the Electrolyte and by its adherence lowers their Electrical
efficiency, I add to the dilute Sulphuric Acid a suitable quantity of Carbonate of
Soda (Washing Soda) for producing the mixture referred to above. This mixture
enables me to bring the plates into excellent form with the same rate of charging
current as that which was before unable to effect the required change. I sometimes put
Bi-Carbonate of Soda into the dilute Acid and occasionally a portion of the Carbonate
and Bi-Carbonate together. At times I also make use of a Solution of Sulphate
of Soda, but whenever possible I prefer employing the Bi-Sulphate as herein
described.
I therefore claim
(1) The use of Bi-Sulphate of Sodium in Secondary cells containing lead and
Per-Oxide or other oxides of lead plates.
(2) The use of Sulphate of Sodium Solution in such secondary cells as are herein
referred to.
(3) The use of Sulphate or Bi-Sulphate of Sodium with dilute Sulphuric Acid in
Accumulators comprising lead and Per-Oxide or other Oxides of lead plates.
(4) The use of Carbonate or Bi-Carbonate of Soda in Accumulators substantially as
set forth.

Improvements in Secondary Batteries.
I, WILLIAM JOSEPH STARKEY BARBER-STARKEY, Aldenham Park, Bridgnorth,
Salop, Barrister, 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 the use of a new electrolyte in secondary cells or
accumulators, and applies chiefly to those accumulators which are commonly known
to comprise dilute sulphuric acid as the electrolyte, and lead opposed to peroxide or
other oxides of lead as the electrodes or plates. The electrolyte I employ is a solution
of bi-sulphate of sodium alone, or a mixture of bi-sulphate of sodium and dilute
sulphuric acid. Solid bi-sulphate of sodium is in several respects more convenient
and useful than sulphuric acid for the purpose under notice, and with its solution
good electrolytic results are obtained. When however the positive and negative plates
in an ordinary secondary battery or cell are whitened by a compound insoluble in the
electrolyte and by its adherence lowers their electrical efficiency, I add to the dilute
sulphuric acid a suitable quantity of carbonate of soda (washing soda) for producing
the mixture referred to above. This mixture enables me to bring the plates into
excellent form with the same rate of charging current as that which was before unable
to effect the required change. I sometimes put bi-carbonate of soda into the dilute
acid, and occasionally a portion of the carbonate and bi-carbonate together. At times
I also make use of a solution of sulphate of soda, but whenever possible I prefer
employing the bi-sulphate as herein described.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is―
1st. The use of bi-sulphate of sodium in secondary cells containing lead and peroxide
or other oxides of lead plates.
2nd. The use of sulphate of sodium solution in such secondary cells as herein
referred to.
3rd. The use of sulphate or bi-sulphate of sodium with dilute sulphuric acid in
accumulators comprising lead and peroxide or other oxides of lead plates.
4th. The use of carbonate or bi-carbonate of soda in accumulators, substantially as
set forth.
