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.
Claims16
A hermetically sealed dry accumulator comprising:
- a case;
- a negative electrode within said case, said negative electrode comprising a metal selected from the group consisting of copper, cadmium, zinc, nickel and iron;
- a porous lead dioxide positive electrode within said case;
- and
- an electrolyte in contact with the positive and negative electrodes, said electrolyte including a solid silica gel infused with a liquid solution of concentrated sulfuric acid and a metallic sulfate, the metallic sulfate concentration in said liquid solution being at least a substantially saturating concentration.
