Advanced thin film thermal battery

Thermal batteries are single-discharge reserve batteries that provide a very long shelf life, minimal self-discharge, wide storage temperature range, fast activation under sudden power demand, and also a wide range of temperature operating conditions. 32Upon activation, thermal batteries are heated with an internal pyrotechnic heat charge above the melting temperature of the molten salt electrolyte. This allows for fast ion mobility and facilitates charge transfer reaction. Due to their unique properties, thermal batteries are primarily used in DoD applications, specifically in munitions and weapon systems. Modern applications and their latest development call for high-performance and cost-efficient thermal batteries. We propose developing, characterization, and optimizing binder/ separator, cathode, and anode. The objective is synthesis of high-performance thin film thermal battery cells and batteries that are scalable in industrial manufacturing. The proposed solution addresses significant market segment, and supports projected markets growth. Along with our development in Phase I and Phase II, we will aim for fully functional prototypes, and market of our technology to DoD agencies. Approved for Public Release | 23-MDA-11635 (9 Nov 23)
