Abstract
Abstract The present invention is directed to an electric current-producing cell which contains: A cathode having as its cathode-active material one or more vanadium compounds selected from: (i) those having the formula: V.sub.a Z.sub.b (1) wherein Z is a chalcogen selected from the group consisting of sulfur, selenium, and sulfur-selenium mixtures, wherein a is a numerical value of about 2, and wherein b is a numerical value of bout 4.5 to about 7; (ii) those having the formula: (NA.sub.4).sub.x VZ.sub.y (2) wherein Z is a chalcogen selected from the group consisting of sulfur, selenium, and sulfur-selenium mixtures, wherein x is a numerical value of about 2 to about 4, and wherein y is a numerical value of about 3 to about 5; and, (iii) those having the formula: H.sub.m (NH.sub.4).sub.n VZ.sub.y (3) wherein Z is a chalcogen selected from the group consisting of sulfur, selenium, and sulfur-selenium mixtures, wherein m is a numerical value of about 1 to about 3 and n is a numerical value of about 1 to about 3, subject to the proviso that the sum of m and n is numerical value of about 2 to about 4, and wherein y is a numerical value of about 3 to about 5. A preferred cathode-electrode material is V a Z b wherein Z is sulfur, a is about 2, and b is about 4.5 to about 5.5. Desirably, this preferred material is obtained from the thermal or chemical decomposition of ammonium thiovanadate (NH 4 ) 3 VS 4 .
