Abstract
A high temperature rechargeable electrochemical cell which comprises a housing containing an anode separated from a cathode by a solid electrolyte separator. The separator is a hollow operatively upright electrode holder defined, in cross-section, by a plurality of peripherally spaced radially outwardly projecting lobes. The operatively lower end of the electrode holder is closed off and the electrode holder has at its operatively upper end a closure having an opening smaller than its cross-sectional dimension. A metallic current collector is disposed in said electrode holder. The current collector is inserted, in a first inoperative configuration, into the electrode holder through the closure opening, and thereafter extended into the lobes of the electrode holder, so that it assumes a second operative configuration in which it has a shape of larger cross-section than the opening.
