Abstract

Surface rich forms of magnesium hydroxide and/or basic magnesium salts, or titanium (IV) oxide, preferably with lye or an aqueous potassium carbonate solution in weight ratios of between about 1:0.5 and 1:2, or between about 1:1.5 and 1:4.5, respectively, produce pastes of a consistency ranging from nearly dry to wet. These pastes are used in producing alkaline primary and secondary elements with immobilized electrolytes and high operating capacities. The specific surfaces of the solids are preferably in the range of from 25 to 50 m.sup.2 /g (and higher). The paste electrlytes can be utilized in the temperature range of from -50.degree. C. to near the boiling point of the pure electrolyte, while exhibiting capacities which scarcely differ from those of an additive-free KOH electrolyte.
