AI Customer ServiceThermally activated (“thermal”) batteries are primary batteries that use molten salts as electrolytes and employ an internal pyrotechnic (heat) source to bring the battery stack to operating temperatures. They are primarily used for military applications, such as missiles and ordnance, and in nuclear weapons.
The battery can be activated at any time without preparation, and will begin supplying power almost immediately. Once activated, the battery functions until a critical active material is exhausted or until the battery cools below the electrolyte’s melting point. What are thermal batteries used for?
Although the extended shelf life of the thermally activated batteries could fit very well with the long system idle time or “hibernation” required in seasonal storage applications, there are several pitfalls to using thermally activated batteries for energy storage applications.
Thermal battery technology is comprised of stacked series cells. Each cell consists of a cathode, an electrolyte, an anode and a pyrotechnic thermal energy source. State-of-the-art thermal battery designs utilize lithium silicon/iron disulfide (LiSi/FeS 2) couple, because it offers the following benefits:
Thermal batteries were conceived and developed by German scientists during WW II and were used in the V2 rockets . The batteries used exhaust heat from the rocket to keep the electrolyte molten in the battery during the missile's mission. Dr. Georg Otto Erb is credited with developing this technology.
It is a relatively new technology that has gained popularity due to its ability to store renewable energy sources such as solar and wind power. The concept of a heat battery is simple: it stores heat during times when excess energy is produced and releases it when there is a shortage of energy.
