WILLIAM BLANCH BRAIN of Cinderford in the County of Gloucester " IMPROVE-
MENTS IN PRIMARY AND SECONDARY BATTERIES AND IN THE MODE OF AND
APPARATUS FOR APPLYING SUCH AND OTHER SECONDARY BATTERIES TO LIGHTING,
POWER HEATING AND OTHER PURPOSES
"
In the Provisional Specification of my patent application dated 30 March 1882
I have described electrodes for secondary batteries consisting of chambers or
envelopes of thin perforated sheet lead containing the red lead or other oxidizing
or deoxidizing or other acting agent. Now according to this invention I materially
increase the efficiency of such electrodes by subjecting them to a considerable
pressure before or after the preliminary charging operation, so as to produce a
plate or body possessing great, solidity and density. Or I may take lead or lead
oxide or other oxide or chloride or oxichloride from an electrolytic chemical or
equivalent bath and form it by the application of considerable pressure into a
plate or body possessing great solidity and density and I may use such electrodes
with or without one or more inserted or otherwise thereto united plates or rods to
ensure conductivity
The primary charging may be in dilute sulphuric acid with or without
chloroform, turpentine or alcholic liquids or enchlorine or chloride of ammonia or
other suitable solution

page_text: These electrodes when applied to ordinary or primary batteries are used in
conjunction with zinc, iron, potassium, amalgam or other electro positive elements
in a solution of sulphuric acid chloride of ammonia enchlorine or any other suitable
solutions.
The accumulative power of my secondary batteries is so enormous as compared
with those of "Faure" and other inventors that one such secondary battery of
mine may be combined with an electric incandescent mining lamp so as to weigh
less than ten pounds all in all, the light being that of several candles and lasting
for hours without recharging. A table, hall, street or other lamp of say 5 to 15
candle power may similarly be combined with my secondary battery of a portable
form and furnishing light for 20 to 60 hours without recharging.
These batteries are applicable to light, heat, power and electro depositing
purposes, and in order that they may be applied for currents of varying intensity
or quantity I use plug switch or shunt appliances by which the battery of accumu-
lator cells can be coupled up so as to vary the electro-motive force of the whole
battery while drawing from each cell the same quantity of current at the same
time; a special feature of this switch appliance is that all the cells become equally
discharged. The switch contacts may be either solid or liquid, in the latter case I
prefer mercury the surface of which is protected from the atmosphere.
This switching arrangement may also be used in conjunction with secondary
batteries in general and also with primary batteries.
