Abstract
Abstract 1. In a thermal battery, the combination in stacked arrangement of (A) a cell assembly containing at least one fusible electrolyte cell including a mass of fusible electrolyte, a cathode, an anode, and heat producing means for energizing the cell, (B) heat sink means comprising at least one heat sink unit disposed at each opposite side of said cell assembly, said unit comprising a protective metal housing containing a fusible metal having a fusion temperature between the maximum operating temperature and the minimum activation temperature of said cell assembly, (C) heat producing means interposed between said cell assembly and the innermost sides of said heat sink units and also disposed at the outermost sides of said heat sink units for fusing said fusible metal, and (D) thermal insulation means at the outermost sides of the stacked arrangement.
