ABSTRACT:
The invention provides an electrochemical cell wherein an anode, solid electrolyte and cathode each comprise a cubic-close-packed framework structure having, as its basic structural unit, a unit of the formula (B.sub.2)X.sub.4.sup.n- which is the structural unit of an A(B.sub.2)X.sub.4 spinel. The structure accommodates active cations M.sup.+ capable of diffusion therethrough. The invention also extends to electrodes and electrolytes of the above type for use in such cells.
