ABSTRACT:
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.
