Abstract
An alkali metal plus halide electrical battery cell of, for example, the sodium and sulfuryl chloride type is disclosed. The disclosed cell provides accommodation for cell chemical reaction products that otherwise preclude achievement of secondary battery action or rechargeable nature in such cells and provides two physical accommodation changes, a reaction space and a reaction space temperature, in the cell arrangement to enable repeated charge and discharge cycling of the cell. The disclosed cell is shown to be embodied in a laboratory type structure and is described with net reaction or end result equations of a combined chemical and physical nature.
