NanoTritium™ batteries are City Labs’ flagship innovation—a revolutionary power source that delivers continuous, ultra-low power for decades, even in the harshest environments. Purpose-built for next-generation microelectronics, NanoTritium™ batteries enable groundbreaking technologies that were once impossible.
At City Labs, we believe power limitations should never constrain innovation. NanoTritium™ technology is how we help engineers, researchers, and innovators design the future—without worrying about frequent battery replacement, recharging, or environmental constraints.
What Are NanoTritium™ Batteries?
NanoTritium™ batteries are solid-state betavoltaic batteries powered by tritium, a safe, stable, and naturally occurring isotope of hydrogen. These batteries use tritium’s natural decay process to continuously generate electricity, delivering consistent, maintenance-free, and long-term energy for up to 20+ years.
Unlike traditional chemical batteries, which store a finite charge that eventually depletes, NanoTritium™ batteries generate their own power through betavoltaic technology—meaning no recharging and no downtime, just reliable power you can trust.
How NanoTritium™ Batteries Work
- Tritium decay releases electrons (beta particles) in a safe, controlled manner.
- Semiconductor materials capture this energy and convert it into electricity.
- Solid-state design means no moving parts, no liquids, and no risk of leaks or explosions.
