PROVISIONAI, SPECIFICATION.
Improvements in Secondary Electric Batteries.
We, THE LITHANODE AND GENERAL ELECTRIC COMPANY LIMITED of
11 Abchurch Lane in the City of London, and JOB THOMAS NIBLETT of
64 Millbank Street in the City of Westminster, Electrical Engineer do hereby
declare the nature of this invention to be as follows:-
66
This invention relates especially to what may be termed solid secondary electric
batteries such as are described in the Specification of Letters Patent No. 14,411
dated 12th September 1890 granted to one of the present applicants namely Job
Thomas Niblett. The object of the present invention is to combine with the
advantages of such a battery the advantages also of the active material called
lithanode." With this object the lithanode materials may be placed in the cell
in the space or spaces provided for the active material or material to be rendered
active as described in the Specification of the aforesaid Letters Patent and the
formation of the lithanode be effected therein but preferably with the employment
of large crystals of sulphate of magnesia or other suitable material so that when
these are removed cells or interstices are provided in the lithanode of an extent
sufficient to contain the requisite electrolyte. Or the battery may be formed or
constructed with alternating elements of spongy lead and lithanode with porous
diaphragms or separators between such as diaphragms or separators of porous clay,
asbestos or the like, the whole being contained in a suitable box or receiver
and provided with the necessary conductors to conduct the current to and from the
elements. °

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:-
This invention relates especially to what may be termed solid secondary electric
batteries such as are described in the Specification of Letters Patent No. 14,411
dated 12th September 1890 granted to one of the present applicants namely Job
Thomas Niblett. The object of the present invention is to combine with the
advantages of such a battery the advantages also of the active material called
" lithanode." With this object the lithanode materials may be placed in the cell
in the space or spaces provided for the active material or material to be rendered
active as described in the Specification of the aforesaid Letters Patent and the
formation of the lithanode be effected therein but preferably with the employment

sufficient to contain the requisite electrolyte. Or the battery may be formed or

page_text: constructed with alternating elements of spongy lead and lithanode with porous
diaphragms or separators between such as diaphragms or separators of porous clay,
asbestos, or perforated vulcanite celluloid or other inert material, or the like, the
whole being contained in a suitable box or receiver and provided with the necessary
conductors to conduct the current to and from the elements.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In secondary electric batteries of the character aforesaid the employment of
lithanode formed so as to be sufficiently cellular to contain the electrolyte
substantially as hereinbefore described.
2. In secondary electric batteries of the character aforesaid the employment of
elements of spongy lead and lithanode with interposed diaphragms or separators
substantially as hereinbefore described.
