Australian researchers led by CSIRO say they have built a proof-of-concept “quantum battery” prototype, demonstrating that a quantum system can charge, store and discharge energy.
The work, conducted with collaborators at RMIT University and the University of Melbourne, was published in Light: Science & Applications.
CSIRO quantum science and technologies leader Dr James Quach, who led the team, said the result supports a predicted quantum effect in which batteries charge faster as they get larger—behaviour that differs from conventional batteries.
According to the release, the prototype uses a multi-layered organic microcavity and is wirelessly charged using a laser. The team used spectroscopy techniques to verify charging behaviour, and reported the device retained stored energy for six orders of magnitude longer than it took to charge.
Fully functioning quantum batteries are not yet available, and the researchers said further work is needed—particularly to extend storage time—before the technology could be considered commercially viable.
Dr Quach said potential future applications could include faster charging for electric vehicles and longer-distance wireless charging for devices, though these outcomes remain prospective.
CSIRO said it is seeking interest from potential development partners.
