Abstract

Thermal batteries are primary batteries containing solid cathodes and anodes sandwiched around an inorganic solid electrolyte that remains inert under ambient conditions until melted using pyrotechnic materials. Today s SOTA thermal batteries rely on complex, heavily engineered systems with large parasitic masses/volumes due to the need for high operating temperatures and thermal retention to maintain those temperatures. Additional volume and complexity is also required for the prevention of catastrophic misfiring and failure from operation at those same high temperatures. This leads to significantly low energy densities compared to Li-ion chemistries. To address this need, ADA Technologies, Inc. propose the development of a chemical reserve Li-ion battery that represents a disruptive change in reserve battery design and could potentially eliminate future demand for thermal reserve batteries. The technology has the potential to provide 3-4x more energy and power than current thermal reserve batteries due to the utilization of high energy/power density Li-ion battery chemistries. These innovations have the potential to enable a substantial improvement in all critical performance criteria for next-generation reserve batteries - including the ability to operate over a wider range of temperatures and operating conditions, enhance safety, lower cost and provide a flexible design.
