摘要:
A bipolar battery assembly of the consumable metal anode type is described. Contact between internal battery elements is now enhanced by air assisted, internally exerted compressive force. Battery elements are constructed in modular manner that assists in the ease of battery assembly and disassembly. Furthermore, ease of anode replenishment is maintained. A multitude of individual cells can now be joined together in an efficient bipolar assembly cell stack for augmented electrical energy generation. In addition to being bipolar, the battery is of rugged construction, providing for dependable, long-life operation that is desirably maintenance-free.

The present invention resides in an expandable anode assembly which comprises an anode riser (14) and anode surfaces (16, 18) on opposite sides of the anode riser. Each anode surface comprises multiple anode sheets (20, 22, 24, 26). Each anode sheet is supported by spring connectors (40, 42, 44, 46) which allow movement of one sheet of an anode surface without movement of the other sheet of such surface. The spring connectors hold each sheet so that its profile remains essentially flat in such movement. Each sheet lies in the same or an essentially parallel plane with other sheets of the anode assembly.

An insulating separator along with an anode for cathodically-protected steel-reinforced concrete is embedded in an ion-conductive overlay on a concrete structure. The insulating separator is at least one sheet of polymer mesh (50). The anode is at least one sheet of highly expanded valve metal in mesh form (2). Both the polymer mesh and the anode mesh comprise mesh having a pattern of voids defined by a network of strands (3) connected at a multiplicity of nodes (4). The surface of the valve metal mesh carries an electrochemically active coating. The insulating polymer mesh separator overlays the concrete structure surface and separates the anode mesh from such surface. Both the polymer mesh and the anode mesh are embedded in the ion-conductive overlay. At least one current distribution member can be fastened to the valve metal mesh.

A massive anode (1) is assembled from many, closely packed modular anodes (2). Although close-packed, the modular anodes (2) are nevertheless spaced apart one from the other. The massive anode (1) has at least substantial inflexibility. It can be particularly useful where a flexible cathode may move toward, and even contact, the anode, e.g., in electrogalvanizing where a moving sheet from a metal coil being coated may thump against the anode. The individual modular anodes (2) provide a collective, generally planar front face toward the cathode. Individual, adjacent modular anodes (2) can be separated at least in part by dielectric spacing members (7) which have portions extending toward the cathode, thereby initially receiving any impact from the cathode.

Electrodes such as mesh electrodes (11) can be in configurations where they are separated from electrode back pans (2) by standoffs (6). The mesh electrodes are very adherently secured to the standoffs. When the electrodes are in need of repair, removal and refurbishing can be a problem. There is now disclosed a method of electrode repair which in large part retains original structure by first removing the mesh electrode and then at least substantially the top of the standoff. A replacement standoff assembly is placed against the retained portion of the original standoff and secured thereto. Refurbished or new electrode mesh can be adhered to the resulting replacement standoff. This may include welding of mesh electrode strands utilizing weld nuggets which are substantially the size of the strands. The refurbishing technique can maintain original separation distances between the back pan and the electrode. The structure provided can be in an "as new" condition without need for repair at an off site location from where the electrode will be used.

The present invention resides in an anode structure as well as in an electrolytic cell utilizing the anode structure. The anode structure comprises a resilsient anode sheet (26) having an active anode surface, and a support substructure (28) for the anode sheet. The anode substructure has a predetermined configuration. Means are provided for flexing the anode sheet onto the anode substructure so that the anode sheet conforms to the configuration of the anode substructure and at the same time provides an adequate electrical junction for uniform current distribution.
摘要:
A battery assembly of the consumable metal anode type has now been constructed for ready assembly as well as disassembly. In a non-conductive and at least substantially inert cell body, space is provided for receiving an open-structured, non-consumable anode cage. The cage has an open top for facilitating insertion of an anode. A modular cathode is used, comprising a peripheral current conductor frame clamped about a grid reinforced air cathode in sheet form. The air cathode may be double gridded. The cathode frame can be sealed, during assembly, with electrolyte. resistant-sealant as well as with adhesive. The resulting cathode module can be assembled outside the cell body and readily inserted therein, or can later be easily removed therefrom.
