Current thermal battery technologies, while highly reliable for critical power applications in missile defense, present limitations that directly impact the performance and capabilities of advanced interceptor systems. Key constraints include their specific energy density, power density, size, weight, and operational lifespan. These factors limit the overall effectiveness and maneuverability of these crucial defense assets. For example, the Standard Missile 3 (SM-3) currently utilizes multiple discrete Lithium thermal batteries to power its various subsystems, each with specific voltage, current, and duration requirements. The size, weight, and performance of these batteries are dictated by the manufacturer (Enersys, EaglePicher, and GYT) and the demands of the design, but there is a clear need for improved performance. A single, more efficient battery solution could greatly simplify the power architecture, reduce weight, and enhance system responsiveness. This SBIR topic seeks innovative research and development to create next-generation thermal batteries that overcome these limitations. We are looking for proposals focused on achieving significant improvements in specific energy density, power density, operational lifespan, and miniaturization. Ideally, solutions would be lightweight, exceptionally safe, and designed to operate reliably in the harsh environments typical of missile defense deployments. Innovations may include, but are not limited to, novel electrolyte chemistries, advanced electrode materials, improved thermal management techniques, and alternative activation methods. The ultimate goal is a new generation of thermal batteries that enable enhanced missile defense capabilities through improved performance, reduced system footprint, and extended operational readiness.
