KERI demonstrates 50-year nickel‑63 beta battery for extreme environments

Korean research institute KERI has demonstrated a nickel-63 beta battery using silicon carbide semiconductors that can generate power for 50+ years in extreme environments without recharging. The prototype achieved 160 microwatts per square centimetre, over 60,000 times higher than previous Korean results, with potential applications in space, deep-sea, and polar remote sensors.
