Scientists take major step towards a working quantum battery

Australian researchers have demonstrated the world’s first proof-of-concept quantum battery, opening new possibilities for faster, more efficient energy storage.

In a new study, scientists have created a proof‑of‑concept quantum battery that can charge, store and discharge energy – the closest step yet towards a working quantum battery. 

Unlike traditional batteries, which rely on chemical reactions, quantum batteries use quantum superposition and interactions between electrons and light, offering the prospect of faster charging and enhanced storage capacity. 

Fully functioning quantum batteries don’t yet exist but advances like this could ultimately transform how we store and use energy. 

The research, led by CSIRO – Australia's national science agency – with collaborators RMIT University and the University of Melbourne, was published today in Light: Science & Applications. 

Study co-author and RMIT PhD candidate Daniel Tibben said the results point to a surprising advantage for quantum batteries. 

“Our study found quantum batteries charge faster as they get larger, which is not how today’s batteries work,” Tibben said. 

“It’s a sign that quantum batteries could one day outperform conventional energy-storage technologies.”

Fellow study co-author and RMIT Professor of Chemical Physics Daniel Gómez said the proof-of-concept device is the closest we’ve ever come to producing a working quantum battery. 

“We demonstrated a device that can be charged, store that energy and then discharge it,” Gómez said.

"This is an exciting development in a rapidly growing interdisciplinary field. 

“Hopefully quantum batteries will soon no longer be a theoretical idea but something than can be built in the lab.” 

Quantum batteries use key effects from quantum mechanics, like superposition and entanglement, rather than the chemical reactions that power today’s conventional batteries. 

The prototype the researchers engineered is a tiny layered organic device that can be charged wirelessly using a laser.

Study lead author and CSIRO Science Leader Dr James Quach said the research offers a glimpse into a possible future powered by quantum energy storage.

"Our proof-of-concept device showcases rapid, scalable charging and energy storage at room temperature, laying the groundwork for next-gen 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.

“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.”

The researchers are focusing on extending the energy storage time for quantum batteries, bringing them closer to being commercially viable.
