Nuclear batteries - also known as radioisotope batteries - work on the principle of utilising the energy released by the decay of nuclear isotopes and converting it into electrical energy through semiconductor converters.
The partners said their small nuclear battery will be designed to provide a reliable power source with a lifespan of up to 50 years without requiring recharging. Utilising advanced materials and innovative design, the battery will convert the energy from the beta decay of a radioactive isotope, such as nickel-63, into electrical energy.
"Nickel-63 nuclear batteries have several promising potential markets due to their unique characteristics and long-lasting power supply," they said.
Applications targeted by the partnership include medical devices, where nickel-63 batteries can power implantable medical devices such as pacemakers, artificial hearts, and cochlear implants. The batteries could also be used by the aerospace industry for long-duration space missions and satellite power. They can also be used in remote sensors, micro-electromechanical systems, and Internet of Things devices that require a reliable and maintenance-free power source. In addition, these batteries can power environmental monitoring devices, industrial sensors, and advanced automation systems, as well as various scientific instruments and equipment.
Kronos and Yasheng noted "consumer electronics like smartphones, laptops, and small household gadgets could benefit from nickel-63 batteries. The potential to create devices that never need recharging would revolutionise the consumer electronics market, although this application is still in developmental stages".
They added: "These diverse applications demonstrate the versatility and potential of nickel-63 nuclear batteries in providing long-lasting, reliable power across multiple industries and sectors."
Under their collaboration agreement, Yasheng Group - a Colorado-based company with historical high-tech agricultural operations in China dedicated to advancing technological innovations - will be responsible for filing the nuclear battery patent in China, while Kronos will handle the filing in North America. Each party will bear the costs associated with filing in their respective countries.
Kronos will receive 10% of the royalties earned by Yasheng in China, and Yasheng will receive 10% of the royalties earned by Kronos in North America.
