Abstract
An electric cell 10 comprising a ceramic porous plate 12 which has previously been soaked in sulphuric acid such that a substantial volume of the pores contain sulphuric acid. Spaces are provided on either side of the plate 12 by a casing 14. The spaces are respectively filled, one with powdered lead-oxide 16, and the other with lead powder 18. Strips of lead 20, 22 extend from adjacent the base of the casing 14 through respectively the lead oxide 16 and the lead powder 18 and through an upper removable cap 24 of the casing 14 to provide terminals 26, 28.
Claims19
An electric cell comprising a self supporting porous member in which a liquid electrolyte is absorbed;
- a first material comprising an anode in contact with the member;
- a second material comprising a cathode in contact with the member;
- and electrical conductors positioned on the porous member and extending through the cell in contact respectively with either the first or second materials.
A method of coating electric cells in an accumulator, comprising the step of dipping the cell in a liquid rubber or plastics material.
