Abstract

An improved gauntlet wet cell battery provides a plurality of elongated hollow spines filled with active material in a cathode array. Bottom ends of the cathode array are closed with an electrically conductive bottom end cap that electrically and mechanically interconnects the free ends of each spine so as to close and substantially rigidly locate the free ends of said spines with respect to one another. In this manner, electrical continuity between the spines is maintained even if one of the spines fractures, cracks, or otherwise becomes mechanically disassociated from an upper portion of the same spine.

Claims

1. An improved gauntlet wet cell battery, comprising:

a substantially fluid-impervious battery case;

an anode plate;

a gauntlet cathode array having a plurality of elongated hollow spines filled with an active material, each spine of the array defining a top end and a distal free end, the spines being electrically and mechanically interconnected at the top ends by an integral structure;

a substantially conductive bottom end cap electrically and mechanically interconnected with the spine free ends so as to close and substantially rigidly locate the free ends with respect to one another;

a plurality of ion-permeable fabric covers substantially encasing the elongated spines; and

an electrolyte in solution with water in the battery case such that the anode plate, gauntlet cathode array, bottom end cap, and fabric covers are all substantially received in the battery case.

2. The improved gauntlet wet cell battery of claim 1, including an ion-porous separator between the anode plate and cathode array.

3. The improved gauntlet wet cell battery of claim 1, wherein the anode plate is also an array having a plurality of elongated hollow spines filled with an active material, each spine of the array defining a top end and a distal free end, the spines being electrically and mechanically interconnected at the top and bottom ends by an integral conductive structure.

4. The improved gauntlet wet cell battery of claim 3, wherein a number of cathode spines is one less than a number of anode spines and the spines are closely packed together.

5. The improved gauntlet wet cell battery of claim 1, wherein the anode plate is manufactured from a material selected from one of the following:

foamed lead, compressed lead wool, lead sheets and composite material.

6. The improved gauntlet wet cell battery of claim 1, wherein the active material in the spines is substantially powdered lead.

7. The improved gauntlet wet cell battery of claim 1, wherein the fabric covers are substantially manufactured from one of a group consisting of carbon fiber, polyester fabric, and Kevlar®

fiber.

8. The improved gauntlet wet cell battery of claim 1, wherein the electrolyte consists essentially of H₉O₄.

9. The improved gauntlet wet cell battery of claim 1, wherein the bottom end cap is substantially manufactured from lead.

10. The improved gauntlet wet cell battery of claim 1, wherein the anode plate is the battery case.

11. The improved gauntlet wet cell battery of claim 1, wherein each spine consists of a central elongated conductor substantially surrounded by an elongated annulus consisting of active material radially restrained by a fabric gauntlet coated with an ion permeable resin.
