Oak Ridge National Laboratory is expanding its Nuclear Battery Initiative to develop long-duration power sources for remote and extreme environments. The program focuses on identifying suitable radioisotopes and improving energy conversion efficiency for applications ranging from deep space exploration to terrestrial national security operations.

These batteries generate electricity through the radioactive decay of isotopes, providing reliable power without human intervention for years or decades. By researching new isotopes and advanced manufacturing techniques, the lab aims to overcome current limitations in thermal management and power conversion. This work supports the broader industry goal of deploying resilient, low-maintenance energy systems for critical infrastructure in locations where traditional power sources are impractical.
