Abstract: A metal-halogen battery, specifically a zinc-bromine battery of the rechargeable type, is disclosed herein and includes a housing, spaced positive and negative electrode plates located within the housing and an arrangement for providing continuous flow of electrolyte solution through the housing between the plates. This battery also includes a network of electrically non-conductive projecting ribs which engage the negative electrode plate for providing a fixed spacing between the two plates but which, at the same time, are specifically designed to reduce dendrite growth.

Abstract: A metal-halogen battery assembly, specifically a zinc-bromine battery assembly of the rechargeable type, is disclosed herein along with its method of operation. The assembly includes a housing having an internal chamber, a liquid separator or membrane which divides the chamber into two sections, a metal-reacting negative section and a halogen-reacting positive section, and two electrodes, a negative electrode fixedly located within the metal-reacting chamber section and a positive electrode fixedly located within the halogen-reacting chamber section. The assembly also includes metal and halogen containing electrolyte solution, a first fixed volume of which is continuously circulated and recirculated through the negative chamber section while a separate, lesser volume of the solution is circulated and recirculated through the positive chamber section.

Abstract: A zinc-halogen cell system is provided in which the electrolyte circulates between the cell and an external storage for the halogen which provides the electrolyte with the necessary halogen concentration for efficient operation, energy efficiencies of about 70% being typically achieved.
