An apparatus includes a thermal battery, which includes a housing and one or more battery cells within the housing. Each battery cell includes an anode, a cathode, and an electrolyte. The electrolyte in each battery cell is configured to be in a solid state when the battery cell is inactive. The apparatus also includes a phase change material around at least part of the housing. The phase change material is configured to conduct external heat into the housing in order to melt the electrolyte in each battery cell and activate the battery cell. The phase change material is also configured to change phase in order to reduce conduction of the external heat into the housing.
