Australian researchers have achieved a milestone in energy storage technology with the creation of the world’s first proof-of-concept quantum battery, according to CSIRO, Australia’s national science agency.
The prototype, developed in collaboration with RMIT University and the University of Melbourne, is capable of charging, storing, and discharging energy, marking the first demonstration of a functional quantum battery.
In a news release, CSIRO said that while fully operational quantum batteries do not yet exist, the research could point to new approaches for energy storage in the future.
Dr James Quach, quantum science and technologies science leader at CSIRO, led the team behind the development.
“My ultimate ambition is a future where we can charge electric cars much faster than fuel petrol cars, or charge devices over long distances wirelessly,” Dr Quach said. “Our findings confirm a fundamental quantum effect that’s completely counterintuitive: quantum batteries charge faster as they get larger. Today’s batteries don’t function like that.”
Quantum batteries use principles of quantum mechanics, such as superposition and entanglement, unlike conventional batteries that rely on chemical reactions.
The CSIRO prototype incorporates a multi-layered organic microcavity and is wirelessly charged with a laser. Advanced spectroscopy confirmed that the device retained stored energy for significantly longer than it took to charge.
Dr Quach said the work highlights the potential for more efficient and rapid energy storage. “Our proof-of-concept device showcases rapid, scalable charging and energy storage at room temperature, laying the groundwork for next-generation energy solutions,” he said.
“While there’s still much work to be done in quantum battery research, we’ve made an important move towards realising the possibilities.”
The team identified extending energy storage time as a key next step. “If we can overcome that hurdle, we’d be that bit closer to commercially viable quantum batteries,” Dr Quach said.
CSIRO is now seeking interest from potential development partners to explore further applications of the technology. The research has been published in the journal Light: Science & Applications.
