Electrochemical cells having solid electrolyte of tubular form. [method of increasing strength of tubular electrolyte material]

Patent ·
OSTI ID:5380905
In an electrochemical cell, such as a sodium--sulfur cell, having a tube of solid electrolyte material separating a liquid alkali metal from a cathodic reactant, the electrolyte tube is surrounded by constraining means which apply an inward pressure as the cell temperature rises. This is achieved either by having a suitable means, e.g., wire, around the tube with a lower coefficient of expansion than the tube, or by putting powder or particles or corrugated metal or other constraining means between the tube and a surrounding housing, the materials being chosen to have appropriate coefficients of expansion to give the required inward pressure. 5 figures.
