Rechargeable battery
First Claim
1. A rechargeable battery comprising:
- a first plate formed of a first sheet of substantially solid metallic foil;
a second plate formed of a second sheet of substantially solid metallic foil;
a first active paste material applied to said first plate;
a second active paste material applied to second to said second plate, the second paste material being charged opposite the first paste material;
a separator for isolating the first and second paste materials; and
reinforcing means for maintaining a substantially constant spacing between said plates during operation and recharging of the battery; and
a casing for enclosing said plates, separator and active materials, the casing providing support for said plates and wherein said reinforcing means includes a plurality of pins extending between opposite sides of said casing through said foil plates.

Abstract
A rechargeable battery is provided having positive and negative plates formed of flexible substantially solid sheets. The plates are each pasted with an active material and separated by a light weight absorbent separator. A light weight casing provides structural support for the plates and encases the battery'"'"'s components. The battery is preferably a recombinant lead acid battery with its plates being formed of lead foil sheets. The casing is preferably reinforced to maintain a constant spacing between the plates by a plurality of support pins extending between upper and lower casing members through the plate sheets. Plates may be stacked one above another to provide a plurality of cells. In separate aspects of the invention, a battery may be formed having a polar plate that has positive and negative surfaces on its opposite sides. In another separate aspect of the invention a novel terminal arrangement is provided.
