Halogen electrodes and storage batteries

Patent ·
OSTI ID:5163457
A composite halogen electrode for a rechargeable metal-halogen energy storage cell comprises a thin foraminous sheet, typically a valve metal with an electroconductive and electrocatalytic nonpassivating coating, in electrical contact over substantially the entire electrode surface with a porous fluid-permeable body (for example, of carbon fibers or sintered valve metal particles) and having throughout its porous structure an active surface coating of electroconductive and electrocatalytic nonpassivating material forming a three-dimensional percolating electrode. The foraminous sheet faces an opposing consumable electrode of a storage cell or battery. During charging halogen evolves essentially at the surface of this sheet, and during discharge halogen contained in an electrolyte is ionized as it percolates through the porous body. 5 figures, 3 tables.
