ABSTRACT:
The invention is related to hermetically sealed dry accumulators having significantly larger power output per units of mass in a proportionately smaller volume. The accumulator includes one electrode comprising copper, cadmium, zinc, nickel, or iron, and another electrode of lead dioxide. An immobilized electrolyte containing a silica gel and sulfuric acid is in contact with the electrodes. A method for producing a novel silica gel which is especially suited for use in the immobilized electrolyte is also described.
