  • Patent number: 8052764
    Abstract: A method of manufacturing thermal batteries is disclosed. In the method according to the present invention, pellets used in the manufacture of thermal batteries are grouped together based on certain material characteristics such as weight, thickness, and density. Pellets with different material characteristics can be grouped together in a single thermal battery to produce a thermal battery with characteristics that are the average of the characteristics of the pellets used to manufacture the thermal battery.
