New battery has life so long you may never have to recharge
Radiocarbon and perovskite unite in a compact nuclear battery promising safe, almost ever-lasting power for extreme environments and miniature tech applications.

The team used carbon-14—an unstable form of carbon known as radiocarbon—and combined it with perovskite materials to create a hybrid battery with improved energy conversion and long-term stability. Doctoral student Junho Lee added, “Although this research involves daily challenges that often seem impossible, we are driven by a strong sense of mission, knowing that the future of our nation is closely tied to energy security.”
