ABSTRACT:
An electrochemical cell comprises a cell casing defining a negative electrode compartment for containing an alkali metal negative electrode; and a plurality of flat plate solid electrolyte electrode holders in the casing and extending parallel to opposed walls of the casing. Each electrode holder comprises a pair of spaced plates and provides a positive electrode compartment containing a liquid electrolyte, and a positive electrode. The positive electrodes are electrically connected in parallel and define, together with envelopes, a positive plate stack. When the cell is fully charged, the major portion of the liquid alkali metal is contained in the negative electrode compartment outside the positive plate stack. Wicking means for the liquid alkali metal are provided adjacent at least the plates of the holders. The level of the liquid alkali metal remains substantially constant in the wicking means.
