A compound electrode incorporating a lead substrate utilizes the lead as a support structure. This support structure provides a surface that engages a valve metal expanded metal mesh. The mesh member has a front and back surface with the back surface facing the lead support structure. At least the front surface of the mesh member is an active surface. Securing of the mesh member to the lead support structure in electrical connection permits the lead support structure to serve as a current distributor for the mesh member. The mesh member may engage the surface of the lead support structure by pressing or rolling the mesh onto the lead. Other engagement means can include the use of fasteners, or welding and the like. The resulting structure can be particularly useful as an electrode assembly for use in an electrolytic cell that serves for the electrowinning of a metal.

The present invention resides in an apparatus for removing chloride ions from a reinforced concrete structure. The apparatus comprises an integrated anode assembly which includes an anode and an electrolyte, the anode being immersed in the electrolyte. The integrated anode assembly is flexible and conformable to the surface configuration of the concrete structure to which it is applied. Means are provided for removably adhering the integrated anode assembly to the concrete structure, conformed to said surface configuration, and for establishing an electric current between said anode and the reinforcement of said concrete structure.

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.

Method of making a unitized electrode assembly

Batteries comprising an anode and liquid electrolyte produce an electrolyte effluent which may contain a solid particulate discharge. This discharge product inhibits the efficient generation of electrical power by the battery. It has been discovered that this solid particulate discharge may be effectively and economically separated from the electrolyte on a continuous basis by a solids separation means comprising a container having an axis and an impeller. This system provides for the efficient generation of electrical power.
