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.
This Wire brief sits within Fusion42's coverage of Energy Storage, Semiconductors and Space Tech.
◆ ◆ The Wire takeaway
You're building an autonomous sensor or beacon for space, deep water or polar regions that dies when the battery runs out. This battery just proved it can run for 50 years without servicing—call KERI this week and find out what it costs to integrate.
