Scientists unveil nuclear battery with 50-year lifespan and triple efficiency
SMRTR summary
Chinese researchers have developed a groundbreaking nuclear battery that maintains performance for 50 years and converts energy three times more efficiently than conventional designs. Their strontium-90 radio-photovoltaic cells with waveguide light concentration structure generated 48.9 microwatts per unit while showing only 13.8% degradation after simulated 50-year radiation exposure, making them ideal for remote locations, space missions, and deep-sea infrastructure requiring long-term, maintenance-free power.
