Solid-state would be the next frontier in relation to electric vehicle (EV) battery technology, but a gaggle of Australian scientists are already well-advanced in the event of next-generation quantum batteries that may charge even faster – and even over long distances wirelessly.
Marking a significant step towards the longer term of energy storage, a gaggle led by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) has unveiled what it claims is the world’s first proof-of-concept quantum battery – a technology that might sooner or later dramatically reduce EV charging times.
Australia’s national science and innovation research agency, in collaboration with RMIT University and the University of Melbourne, has demonstrated a functioning prototype able to charging, storing and discharging energy using quantum mechanics moderately than traditional chemistry.

While still in its infancy, the CSIRO says the technology could eventually underpin next-generation EVs and consumer devices with near-instant charging capabilities.
“My ultimate ambition is a future where we are able to charge electric cars much faster than fuel petrol cars, or charge devices over long distances wirelessly,” said Dr James Quach, CSIRO’s quantum science and technologies leader.
How a quantum battery works
Unlike today’s lithium-ion batteries – which depend on chemical reactions – quantum batteries make the most of quantum phenomena equivalent to superposition and entanglement.
The prototype developed by the Australian team uses a multi-layered organic microcavity and is charged wirelessly via a laser, highlighting the potential for cable-free energy transfer in the longer term.
One of the vital intriguing findings is how the battery behaves because it scales.
“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,” Dr Quach said.
This counterintuitive property might be key to enabling rapid charging for larger systems, including electric vehicles.
“The research validates the exciting potential of quantum batteries for unprecedented efficient and rapid energy storage,” added Dr Quach.
What it means for EVs
If successfully developed for business use, quantum batteries could address one in all the largest barriers to EV adoption: charging time.
As a substitute of waiting 20 to 40 minutes at a DC fast-charger – or hours at home with an AC power outlet – future EVs equipped with quantum batteries could theoretically charge in seconds or minutes, potentially even faster than refuelling a petrol- or diesel-powered automobile.
There’s also potential for wireless charging over long distances, removing the necessity for physical charging infrastructure altogether.
Still a protracted road ahead
Despite the breakthrough, fully functional quantum batteries are still a great distance from production.
The present prototype has demonstrated promising behaviour, including the flexibility to retain stored energy for thousands and thousands of times longer than its charging duration.
The research team used advanced spectroscopy techniques to substantiate the prototype’s charging behaviour, which showed it retained stored energy for six orders of magnitude longer than it took to charge.
Nonetheless, there are still major hurdles to beat.
“The subsequent step for quantum batteries at once is extending their energy storage time,” Dr Quach said.
“If we are able to overcome that hurdle, we’d be that bit closer to commercially viable quantum batteries.”
The larger picture
The CSIRO says it’s now in search of industry partners to assist further develop quantum battery technology.
So while commercialisation could also be years away, the research confirms key theoretical predictions and provides a glimpse right into a future where energy storage is quicker, more efficient, and potentially wireless.
For the automotive industry, it could represent a fundamental shift – not only improving EV charging speeds, but redefining how vehicles are powered altogether.
“Our proof-of-concept device showcases rapid, scalable charging and energy storage at room temperature, laying the groundwork for next-gen energy solutions,” Dr Quach said.
“While there’s still much work to be done in quantum battery research, we’ve made a vital move towards realising the chances,” he said.
