Australian researchers have created the world’s first proof-of-concept quantum battery, opening research into a new generation of energy storage devices.
The pioneering technology could transform energy storage and delivery, offering the potential for devices to charge at unprecedented speeds.
The project was led by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in collaboration with the University of Melbourne and RMIT University. Findings from the study were published in ‘Nature Light: Science & Applications.’ Key contributors included Associate Professor James Hutchison and Professor Trevor Smith from the University of Melbourne.
Associate Professor Hutchison said that, “Similar to conventional batteries, quantum batteries charge, store, and discharge energy. But unlike everyday batteries that rely on chemical reactions, quantum batteries exploit the principles of quantum mechanics. The advantage of quantum systems is that they absorb light in a single, giant ‘super absorption’ event, enabling much faster charging.”
To test the prototype’s performance, researchers employed the University of Melbourne’s Ultrafast Laser Laboratory within the School of Chemistry. Using advanced spectroscopy techniques, they were able to observe and confirm the battery’s ultrafast charging behavior.
Professor Smith noted that, “Our Ultrafast Laser Lab, with dual femtosecond laser amplifiers and tunable optical parametric amplifiers, allowed us to record ultrafast signals over multiple orders of magnitude in time, providing crucial verification of the battery’s rapid charging capabilities.”
Dr. James Quach, quantum science and technologies leader at CSIRO, said that, “This proof-of-concept validates the exciting potential of quantum batteries to achieve rapid, scalable charging and energy storage at room temperature. It lays the groundwork for next-generation energy solutions.”
A striking aspect of the research is the counterintuitive quantum effect observed: the battery charges faster as it increases in size.
“While much work remains in extending the energy storage time, this milestone marks a significant step toward realizing the possibilities of quantum-based energy systems,” Dr. Quach added.
The breakthrough opens the door to future technologies powered by quantum batteries, potentially reshaping sectors ranging from consumer electronics to large-scale energy infrastructure.
