Abstract

In a battery of electrochemical unit cells in which an active metal in powder form is an electrode, high rate reaction at high efficiency is achieved by slurrying the powdered metal in the cell electrolyte. The slurrying is carried out entirely within each cell so that no transfer of electrolyte to and from the cell during discharge is necessary. Such batteries are suitable for powering vehicles. A battery of such cells can be emptied and then refuelled either by pressure or by vacuum; in one embodiment the active metal can be regenerated in each of the cells from the discharge products formed therein.
