In an electrochemical cell of the type having a solid ceramic electrolyte between its anode and cathode, the electrolyte is dome-shaped, in the form of a thin curved shell of ceramic material such as a beta alumina. The domed configuration of the electrolyte reduces the weight that is required to withstand internal pressure differential generated across the electrolyte in discharge, and also reduces internal resistance of the cell.

An electrochemical cell comprising, in sequential adjoining order, a first current collector, anode material contained in an anode chamber, a solid, ionically conductive ceramic electrolyte, cathode material contained in a cathode chamber, and a second current collector; and annular means surrounding and closing said anode and cathode chambers, said anode and cathode materials being electrochemically active during operation of the cell, said electrolyte formed of a ceramic material across which ions are transferred during discharge of the cell from one said chamber to the other said chamber, said electrolyte and first and second current collectors all being in the form of domed disks of substantially similar curvature, said electrolyte and current collectors being axially aligned but spaced apart, to present said chambers between them.
