Technology excellence Advanced Thermal Batteries, Inc. is the leading supplier of advanced thermal batteries that are used to power missiles, rockets, launch vehicles, torpedos, munitions, and egress systems. ATB supplies products to all the major defense contractors including Boeing, Raytheon, Lockheed Martin, General Dynamics, and Northrop Grumman. ATB is the only US Company offering a full range of Li based and metal disulfide electrochemical options. ATB can provide the best trade-off between performance and cost because of this wide range of options. The general distinction of thermal battery technologies is related to the type of anodes. From an electrochemical point of view, lithium is the most valuable element due to its high reducing potential and its high specific coulombic capacity. As its melting point is lower than the thermal battery operating temperature, alloyed forms are used such as LiAl (Lithium Aluminum) or LiSi (Lithium Silicon). We also offer our patented lithium-iron mixture, named LAN (Lithium Anode), an exclusive ASB-Group technology. which results in higher cell voltage, higher power and improved safety.
