Benefits of NanoTritium™ Batteries in Aviation, 
Avionics, and Aerospace Systems

City Labs’ betavoltaic power sources offer unmatched longevity and reliability, allowing aerospace engineers to design systems that perform autonomously for decades. Unlike chemical or solar-based solutions, NanoTritium™ batteries generate continuous power through the natural decay of tritium, unaffected by darkness, temperature, or motion.

From orbital satellites to high-altitude aircraft, NanoTritium™ batteries provide dependable micro-power for sensors, guidance systems, and mission telemetry. Their solid-state construction eliminates leakage, degradation, and recharging requirements—making them ideal for sealed or inaccessible aerospace environments.
