A battery and method of making such battery, adapted to operate at low (typically ambient) temperatures for a short initial period and thereafter at higher temperatures. A Li-Mg alloy anode is provided, comprising up to 25% magnesium , in a liquid thionyl chloride bath which as the cathode for high temperature operation. A thin, substantially pure lithium layer is applied to a surface of the Li-Mg anode, preferably in the range of 0.0019 to 0.0025 inches (.04826-.0635mm), to allow obtaining of sufficiently high power and voltage output at lower temperatures for a short period where at such lower temperatures the required voltage and power would not otherwise be available from a Li-Mg anode. Thereafter, the battery may thereafter be used in, and exposed to, higher temperatures of up to 220 °C where at such temperatures the necessary voltage and power from the remaining Li-Mg alloy anode is then available. |
