Abstract
A primary electric cell comprising, in combination: PA0 (a) an anode consisting essentially of a metal selected from alkali metal, calcium and magnesium, and alloys of two or more of said metals which alloys are solid at temperatures up to 75.degree. C.; PA0 (b) a liquid solution having a conductivity of at least 1 mMho.cm.sup.-1 and comprising: PA1 (i) a non-aqueous cathode consisting of an aprotic, reducible organic compound capable, under the conditions prevailing in the cell, of rapidly reacting with the metal of said anode, so as to form on the surface thereof a thin, compact, insoluble layer of solid electrolyte having t.sub.e -=0 and t.sub.M + substantially equal to 1; and PA1 (ii) an electrolyte being a salt of the cation of the metal of said anode and a large complex anion; and PA0 (c) an inert, porous cathodic collector consisting of carbon or graphite or of compressed carbon or graphite powder optionally with a suitable binder.
