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.

A bipolar battery having a consumable metal anode and being of the filter-press type is described. Internal battery contact is obtained by pressure connection transmitted virtually all, to completely, by end bulkheads. A multitude of adjoning cells can be placed together in a bipolar assembly cell stack. Yet the battery is compact and lightweight.
摘要:
A composition and method of manufacture of electrodes having controlled electrochemical activity to allow the electrodes to be designed for a variety of electro-oxidation processes. The electrodes are comprised of a compact coating deposited onto a conductive substrate, the coating being formed as multiple layers of a mixture of one or more platinum group metal oxides and one or more valve metal oxides. The formation of multiple layers allows the concentrations of platinum group metal and valve metal to be varied for each layer as desired for an application. For example, an electrode structure can be manufactured for use as an anode in electroplating processes, such that the oxidation of the organic additives in the electrolyte is markedly inhibited. Another electrode can be manufactured to operate at high anodic potentials in aqueous electrolytes to generate strong oxidants, e.g., hydrogen peroxide or ozone.

An aqueous electrolyte aluminum-air battery comprises one or more cells, each cell comprising a frame which defines an electrolyte chamber. The frame is made of a rigid material inactive to the electrolyte. The cell has a consumable aluminum anode and an air cathode spaced from the anode by said electrolyte chamber. Means are provided for admitting electrolyte solution into the electrolyte chamber. A vent exposes the electrolyte chamber to atmosphere. A hydrophobic membrane which is impermeable to the passage of electrolyte but permeable to the passage of hydrogen closes the vent. A surface of each cell anode is exposed to the flow of air. The amount of surface exposed is effective to dissipate heat generated at the anode.

High concentrations of hypochlorous acid can be produced from, most typically, brine using an system of simple design with minimum residual salt production, reduced power consumption, and at high operating efficiencies. This is accomplished by separating the system into two operations, each of which is preferably optimized. This process employs at least two electrochemical cells, the first of which has no separator between the anode and cathode and generates a high-strength hypochlorite solution. The hypochlorite is then diluted to a desired chlorine concentration and/or pH and fed into the anode compartment of a second electrochemical cell wherein the electrodes are separated by a barrier, such as, for example, a membrane or diaphragm. The separated cell produces a solution containing predominantly hypochlorous acid. Separation of the neutralization processes allows storage of hypochlorite which has a much greater stability in regards to temperature which can then be subsequently converted into hypochlorous acid at point of use or as needed or desired.
