Abstract
Abstract An electrical energy storage device is provided which has a pair of spaced aluminum-lithium alloy anodes with an active carbon cathode interposed therebetween and the anodes and cathodes are separated by an inert spacer material containing a fused salt electrolyte. This device is assembled by enclosing the cathode in a fiber mat, which functions as the spacer, positioning the cathode in a screen basket, closing the basket to contain the cathode, inserting the screen basket into a container, positioning an anode within the container on each side of the screen basket, and hermetically sealing said container.
